A full integration would require registering an opencode plugin with a `permission.ask` hook plus bridging Claude CLI's `--permission-prompt-tool` through a local MCP server; opencode's `permission.ask` hook is reactive (it only intercepts opencode-initiated asks, not provider-initiated ones), so a non-trivial bridge is required. Contributions welcome. +- **No native opencode permission dialog for CLI-initiated asks**: when `skipPermissions: false`, this provider now handles Claude `can_use_tool` control requests itself (auto allow/deny). That prevents deadlocks and enables policy control, but it still does not open opencode's built-in permission modal. Full parity requires opencode core exposing a provider-facing permission bridge plus a CLI control-request adapter. ## Publishing diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index c99e0ba..33dbe6e 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -10,6 +10,7 @@ import type { import { generateId } from "@ai-sdk/provider-utils" import type { ClaudeCodeConfig, + ControlRequestBehavior, ClaudeStreamMessage, ReasoningEffort, } from "./types.js" @@ -114,6 +115,101 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { return "default" } + private controlRequestBehaviorForTool(toolName: string): ControlRequestBehavior { + const configured = this.config.controlRequestToolBehaviors + if (configured && toolName) { + const direct = configured[toolName] ?? configured[toolName.toLowerCase()] + if (direct === "allow" || direct === "deny") return direct + + const lower = toolName.toLowerCase() + for (const [key, behavior] of Object.entries(configured)) { + if (key.toLowerCase() === lower && (behavior === "allow" || behavior === "deny")) { + return behavior + } + } + } + + return this.config.controlRequestBehavior ??

The opencode session ID comes from the `x-session-affinity` header opencode sets on LLM calls to third-party providers (see `packages/opencode/src/session/llm.ts`), so two chats opened simultaneously in the same project against the same model get separate CLI processes instead of racing on one. +--- -- **Same chat, multiple turns**: the CLI process stays alive between messages.

Aligns with opencode core's mergeDeep semantics so the bridge sees the same effective config opencode does. - Discovery aligned with opencode core: walks parents up to the worktree root, loads opencode.json + opencode.jsonc at each level, includes home-dir .opencode/, OPENCODE_CONFIG ordered before project walk-up. - Hot-reload: bridgeOpencodeMcp now returns {path, hash}. The cached claude subprocess is evicted between turns when the hash differs, so on-disk MCP edits are picked up without restarting opencode or starting a new chat. - Runtime overlay: opencode's /mcps UI toggle is in-memory only (client.mcp.connect/disconnect, never written to disk). Plugin now captures the SDK client and calls client.mcp.status() each turn, overlaying connected->enabled and anything else->disabled onto the disk merge before hashing. - Tests: new test-bridge.ts with 23 cases via node:test + tsx covering merge semantics, walk-up boundaries, jsonc precedence, runtime overlay, and hash stability. --- src/claude-code-language-model.ts | 87 +++++- src/index.ts | 46 ++- src/mcp-bridge.ts | 447 +++++++++++++++++++++++------- src/opencode-types.ts | 19 ++ src/runtime-status.ts | 49 ++++ src/session-manager.ts | 31 ++- src/types.ts | 14 + test-bridge.ts | 415 +++++++++++++++++++++++++++ 8 files changed, 987 insertions(+), 121 deletions(-) create mode 100644 src/runtime-status.ts create mode 100644 test-bridge.ts diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 95a3b83..946ba42 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -16,7 +16,8 @@ import type { } from "./types.js" import { mapTool } from "./tool-mapping.js" import { getClaudeUserMessage } from "./message-builder.js" -import { bridgeOpencodeMcp } from "./mcp-bridge.js" +import { bridgeOpencodeMcp, type RuntimeMcpStatus } from "./mcp-bridge.js" +import { getRuntimeMcpStatus } from "./runtime-status.js" import { getActiveProcess, spawnClaudeProcess, @@ -111,22 +112,35 @@ export class ClaudeCodeLanguageModel implements LanguageModelV3 { } /** - * Build the combined `--mcp-config` list: user-configured paths plus the - * auto-bridged opencode MCP config (when enabled and present) and the - * proxy MCP scratch file (when proxyTools are enabled). + * Build the combined `--mcp-config` list and return both the list and the + * hash of the bridged opencode MCP block (or null when bridging is off / + * yields nothing).

Identity-checked against package.json name and description, skips if user lists the unscoped name in their plugin config, never self-deletes.

Sonnet routinely takes 5+ seconds to transition from a chat-text block to its next tool_use block, which guillotined the stream mid-turn with reason=stop and zero usage. Reframe the timer as a wire-inactivity watchdog: reset on every line received from the CLI, fire only after extended silence on stdout. Bump the default threshold from 5s to 60s for normal flow; the abort grace path keeps a short 5s window by passing it explicitly. The session-reuse hang the timer was originally added to catch (CLI emits content but never sends a result) is still covered.

placeholders and guard drain race on result Two bugs caused MCP servers to disappear from Claude CLI's view and proxy tool calls to time out: 1. {env:VAR} placeholders not substituted in bridged MCP config. translateServer wrote the raw spec.environment / spec.headers through to the Claude CLI --mcp-config file, so any server using opencode's interpolation syntax received the literal string '{env:VAR}' as its credential value.

The plugin no longer emits the empty block (which was triggering Anthropic 400s like `cache_control cannot be set for empty text blocks`). +- **Smart incomplete-turn continuation.** By default, the plugin keeps the current opencode stream open and feeds Claude CLI a small internal continuation message when Claude emits a `result` after reasoning/tool activity without a useful visible answer.

Resets on every line received, so long mid-turn pauses (Sonnet between text-end and the next tool_use, for example) are tolerated. On a user-initiated abort, the watchdog shortens to 5 seconds. - **Per-iteration usage.** When the CLI internally retries with tools, the plugin only counts the last iteration's usage so opencode's context accounting stays accurate. diff --git a/package.json b/package.json index 3b02e99..2b20039 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-auto-continue.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 0e16189..b6f71bf 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -91,6 +91,121 @@ function hasNewUserContent( return false } +const AUTO_CONTINUE_MAX_ATTEMPTS = 8 +const AUTO_CONTINUE_MAX_ELAPSED_MS = 10 * 60 * 1000 +const AUTO_CONTINUE_NO_PROGRESS_LIMIT = 2 + +const AUTO_CONTINUE_PROMPT = + "Continue the task from where you stopped.

Mid -task narration like 'Implementing now. Updated the search index.' hit those keywords reliably and short-circuited the auto-continue to 'final-answer' — STOP — even though the next text block was a mid-task pause and the user still expected more work. Track lastVisibleText separately: reset on each new text content_block start, append on text deltas. Pass it through AutoContinueSnapshot. Final-answer detection now considers only the most recent text block, which is the actual candidate end-of-turn sentence. Question / blocker detection still uses the accumulated text — a question raised earlier in the turn should still block auto-continue. Also add file-based logging at $XDG_DATA_HOME/opencode-claude-code/ plugin.log (defaults to ~/.local/share/opencode-claude-code/plugin.log) so NOTICE/WARN/ERROR are observable without depending on DEBUG=opencode-claude-code or stderr redirection.

Result: the gate let the prompt through but the message builder emitted the '(empty)' sentinel, so Claude CLI saw a no-op turn and ended it — forcing the user to press 'continue' between every proxy tool call. Symmetric fix: when iterating recent messages, also extract tool-result parts from tool-role messages. Matches hasNewUserContent's shape so the two functions agree on where to find tool-results. Tests: 4 new in test-get-claude-user-message.ts cover tool_result emission, multiple results per message, sentinel fallback when a tool-role message has no tool-result parts, and mixed user+tool content.

This works across every Claude 4 family model the CLI supports. + +What you see is a **summary** of the model's thinking, not the raw chain-of-thought. Anthropic [stopped exposing raw thinking on the Claude 4 family](https://platform.claude.com/docs/en/build-with-claude/extended-thinking#summarized-thinking) and ships a server-generated digest instead. For Claude Opus 4.7 specifically, [thinking content is omitted from responses by default](https://platform.claude.com/docs/en/about-claude/models/whats-new-claude-4-7#thinking-content-omitted-by-default); the plugin opts back in by passing `--thinking-display summarized` on every spawn. Claude Code CLI 2.1.142+ is required for that flag to take effect; older CLIs skip it silently. + +### Reasoning effort variants + +Each model exposes `low` / `medium` / `high` / `xhigh` / `max` variants. Picking one injects the corresponding Claude CLI thinking keyword (e.g. `(ultrathink)` for `max`) into the user message.

From that point on, this.config.cwd was frozen, defeating the process.cwd() lazy fallback that previously made workspace-aware behavior work. Workspace switches in opencode's UI never updated a value set at plugin init, so Claude CLI stayed pinned to the first-opened workspace. - Move captured directory + resolution helpers into runtime-status.ts (existing cycle-break module). - Add resolveSpawnCwd(configured) with priority chain: 1. explicit options.cwd (user override always wins) 2. live process.cwd() when usable (restores lazy resolution) 3. captured directory from plugin init (rescues macOS GUI at /) 4. process.cwd() as final fallback - Stop baking opencodeProjectDirectory into mergedOptions in index.ts. - Swap the two spawn sites in claude-code-language-model.ts to use resolveSpawnCwd(). - Add test-cwd-resolution.ts (9 tests) covering every branch via a testable resolveSpawnCwdFrom inner function. - Document the rule in AGENTS.md so future me doesn't reintroduce. Does NOT fix desktop GUI launches where opencode does not chdir on workspace switch (process.cwd() stays at /). That requires tier-two work (event-hook listener or runtime directory query).

Opt-in: default `proxyTools` stays the existing four (Bash/Edit/Write/WebFetch).

Mechanism mirrors the existing four proxies: Claude calls `mcp__opencode_proxy__task` via --mcp-config, the parked HTTP request drains into the AI SDK stream as a tool-call with `toolName: "task"` (matching opencode's native tool name, providerExecuted: false), opencode runs its task tool, and extractPendingProxyResult matches by callId to resolve the parked MCP call. The 10-minute PROXY_CALL_TIMEOUT_MS cap applies. Long subagent runs near that ceiling are a known constraint until per-tool timeouts exist.

State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session.

Ignore it quietly; do not treat it as an error. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. +- Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4.

The tool_use was collapsed to a faint `_Asking: _` line in three code paths — dropping every option, header, and any question past the first. Replaced with formatAskUserQuestion(): a shared renderer that emits all questions with headers, enumerated options + descriptions, and a single/multi-select reply hint as visible markdown (same approach as ExitPlanMode; opencode has no native structured ask-question executor to proxy through). 2. The CLI control gate auto-allowed AskUserQuestion, letting the headless Claude CLI resolve its own question with no TTY (fabricated or empty answer) and proceed on a guess. controlRequestBehaviorForTool now hard-denies AskUserQuestion (explicit controlRequestToolBehaviors config still overrides), with a specific deny message telling the model to stop and wait for the user. The tool_use is still streamed and rendered, and the turn stops for a real answer. Re-applied on upstream v0.4.23 after the duplicate local Task-proxy commits were dropped (upstream shipped the identical feature as 9a31ae8 / PR #5, authored by galvani).

Without a unique affinity, two sessions sharing the same process.cwd()+model can collide on the same session key and resume the wrong Claude CLI conversation. Inject input.sessionID from the chat.params hook into providerOptions as opencodeSessionID, before the agent guard. resolveSessionAffinity() reads it as a fallback when the header is absent, so each opencode session gets an isolated session key and separate Claude CLI process.

When non-tool blocks (text, thinking) precede a tool_use, that index does not align with the toolCalls array, so partial_json chunks updated the wrong (or no) entry. 2. On each input_json_delta chunk, `tc.args = JSON.parse(partial_json)` either replaced args with a slice or silently swallowed the chunk on parse failure. Partial chunks never accumulated into a full object. 3. The Claude CLI child process was not killed on spawn error and was only relying on the readline close path on the happy case. Fix: - Track streaming tool_use blocks in a Map keyed by content-block index, accumulating partial_json into an `inputJson` string buffer. - Parse `inputJson` at content_block_stop and push the result to toolCalls. Log a warning on JSON parse failure instead of swallowing. - Add a cleanup() that kills the child on error, on result, and on readline close.

From d03e33f17214c7ba6d5a827a1288dcde01a9a995 Mon Sep 17 00:00:00 2001 From: Jan Kozak Date: Mon, 25 May 2026 15:59:49 +0200 Subject: [PATCH 116/211] fix(provider): inject full model definitions via config hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit opencode loads plugin `provider.models` hooks before extending the provider database from config. For plugin-only providers — those that don't exist in the public models-dev catalog, e.g. `claude-code` — the `provider.models` hook bails (the `database[providerID]` lookup is empty), so model fields (limit, cost, family, name, capabilities, release_date) stay at their schema defaults of 0/empty/false. Symptom: the session-context-usage indicator and context tab in the web UI show 0 / no percentage / no cost / no model name for any claude-code session, even though message tokens are populated correctly. Other providers (deepseek, anthropic, openai) render fine because their metadata is in models-dev. `configModelsForProvider` already exists and produces models in the flat config schema opencode expects; it was wired into the multi-account expand path but not the default single-provider path. This change adds it to the default config-hook output so opencode sees real limits/costs/etc. when it builds the database from config. Also: `configModelsForProvider` previously only read `api.npm` / `api.url` from `existing` config — it did not preserve user-defined `variants`. Switching to it as the single source of models would silently drop custom variants users had added to their `opencode.json`. Updated the function to merge `existing.variants` on top of the default-model variants (user values win on key collision), so user overrides survive the round-trip. (Reported by Gemini Code Assist on the initial draft of this PR.) Verified by hitting `/config/providers` before and after — claude-code now reports `limit.context`, `cost.input`, `family: "opus"`, `capabilities.reasoning: true`, etc. instead of zero/empty defaults.

Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`).

ClaudeSession.tailTurn re-emits transcript records; claude-session-wrapper adapts it to the ActiveProcess contract and synthesizes a result line so the existing finish branch runs unchanged. Headless stays the default. Also fix an orphan tool-result for skipped internal tools on the non-partial branch (register toolCallsById only inside !skip, mirroring the streaming path).

Do not delete or override `CLAUDE_CODE_DISABLE_THINKING`, `CLAUDE_CODE_DISABLE_ADAPTIVE_THINKING`, or explicit `CLAUDE_CODE_SHOW_THINKING_SUMMARIES` values. - Reasoning stream parts are only started after the first non-empty `thinking_delta`. This prevents empty Thinking rows when the CLI opens a thinking block but streams no text. +- opencode's own reasoning features (e.g. v1.17.0 "Added Claude Fable reasoning support", vLLM interleaved `reasoning` field) live in opencode's **native** Anthropic/vLLM runtime, which this plugin deliberately bypasses by routing through the `claude` CLI. There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. +- Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. +- `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. +- Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (which is exactly what this plugin spawns via `--print`) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. No code change needed — this is account-side billing the plugin can't influence. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. +- `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id.

Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session.

Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The system prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); without it interactive sessions never see opencode agent prompts. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). (5) The `Bun.Terminal` capability gate falls back to headless silently. (6) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`).

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. - Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×. These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus 4.8. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75). Haiku ($1/$5), Sonnet ($3/$15), and Fable/Mythos ($10/$50) were already correct. If you add a model, set its cost from the published standard (not Fast Mode) pricing so the `(N×)` suffix stays consistent. -- Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (which is exactly what this plugin spawns via `--print`) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected.

Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`. - `tool-input-delta` parts must only be forwarded for tool calls whose `tool-input-start` was actually emitted. opencode's AI SDK bridge (`packages/opencode/src/session/llm/ai-sdk.ts`) resolves delta/end names via `state.toolNames[event.id] ?? "unknown"`; a delta for an unseen id creates a permanently-pending part with `tool: "unknown"` that the TUI renders as `⚙ unknown`. Skipped tools (ToolSearch, TaskCreate/TaskUpdate, CLI-internal WebSearch, AskUserQuestion, ExitPlanMode, proxy tools) stream `input_json_delta` like any other tool_use, so the streaming site in `claude-code-language-model.ts` gates delta forwarding on a `started` flag set only when the input-start part went out (fixed after v0.8.1). Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. @@ -52,7 +52,7 @@ - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message.

The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message.

(2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process.

Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. KNOWN ISSUE (open as of v0.9.0, shipped experimental): with `interactive: true`, starting a *fresh* opencode session under Bun can leave the TUI blank/unresponsive before the first keystroke — i.e. BEFORE any `doStream`/interactive spawn runs, so `plugin.log` does not capture it. `opencode --continue` (resumed session) works, and once a session is live the transport is stable and reused (verified 2026-06-10: this very session ran on interactive, spawned once, reused for ~25 min). The child `claude` PTY is isolated (`Bun.spawn` `terminal:{}` at `claude-session-bun.ts:205`, output captured to a buffer, only echoed to real stdout in `debug`), so terminal contention is ruled out as the cause.

Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`).

Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. - Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. -- `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. +- `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`.

Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 6e55910..7083509 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -208,6 +208,16 @@ interface AutoContinueState { noProgressCount: number lastSignature?: string aborted?: boolean + /** + * Latched true once AskUserQuestion is rendered this turn.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically. Do not re-investigate adopting opencode's native reasoning; it would mean abandoning the CLI wrapper. -- Model display names carry a list-price multiplier as a `(N×)` suffix (`src/models.ts` `defineModel`, via the `multiplier` field): haiku 1×, sonnet 3×, opus 5×, fable 10×, mythos 10×.

From September 1: switch it to `sonnetCost` ($3/$15), multiplier 3×, update the README model table + pricing paragraph and the `test-config-models.ts` assertions (name suffix becomes `(3×)`, cost fields change). The plan is to have an open PR staged with this change and merge it just before Sept 1. +- `opusCost` in `src/models.ts` is the real Opus 4.5+ standard price ($5/M in, $25/M out — corrected from a stale legacy $15/$75; Opus 5 keeps it).

New-generation entries (Sonnet 5, Opus 5) use `output: 128_000` (the models' real max output); the older entries still say 16_384 for historical reasons — raising them is a candidate follow-up, don't mix conventions within a release. - Billing context (researched 2026-06-10, documented in README "Billing change: June 15, 2026"): from 2026-06-15 Anthropic bills `claude -p` / Agent SDK usage (the plugin's default headless `--print` path) against a separate monthly Agent SDK credit on subscription plans (Pro $20 / Max 5x $100 / Max 20x $200), not normal plan limits; API-key auth is unaffected. Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`). Explicit opencode-tool routing (`webSearch: ""`) still forwards with `executed: false`. Tests in `test-tool-mapping.ts`.

charset=UTF-8 Content-Transfer-Encoding: 8bit The CLI treats --session-id as 'create a NEW session with this UUID' and exits with 'Session ID ... is already in use' whenever a transcript for that ID already exists on disk — so every respawn that tried to continue a session (MCP hot reload, eviction, crash recovery) failed, cleared the session, and fell back to re-injecting history as text. Verified against the real CLI: --session-id reuse fails with no live process holding the ID; --resume continues under the same session ID.

Keep accumulating `inputJson` unconditionally — the skip-path text rendering (AskUserQuestion/ExitPlanMode/WebSearch) depends on it. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). +- proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. +- Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

This was masked before the per-tool proxy timeout fix because the flat 10-minute ceiling ended the turn first; now that a long proxy-blocked task call blocks and returns successfully, resuming the reused child afterwards can leave it producing nothing (live ses_0cfc0da6 step 8 — idle, 0% CPU, no network, no error, needed a manual Esc). Add a start watchdog (doStream, fresh-turn path only; default 90s, env CLAUDE_CODE_START_WATCHDOG_MS). On first fire it respawns the child via respawnActiveProcess, which kills the wedged child but reuses its proxy server, system-prompt file, and mcp hash (handles baked into cliArgs) and appends --session-id so the conversation resumes transparently. A second fire ends the turn with an error so the next turn spawns fresh.

Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. +- Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's.

The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. +- Startup diagnostics (`src/startup-diagnostics.ts`, roadmap #3): one `NOTICE: claude-code plugin ready` block emitted once per process from the `config` hook in `index.ts`, replacing the older "registered claude-code provider(s)" notices.

It is fire-and-forget (`claude --version` is async, 5s timeout, cached) and every field is wrapped so diagnostics can never break provider registration. `describeSpawnCwd` intentionally mirrors `resolveSpawnCwd`'s priority order and a test asserts they never disagree — change both together. The MCP list is the **disk-only** merge (`mergeOpencodeMcp`, split out of `bridgeOpencodeMcp` so diagnostics never writes a scratch config): opencode's runtime status isn't settled at plugin init, so the per-turn overlay is deliberately not applied. `opencode` reads "unknown" on real opencode: as of **1.17.18** nothing reachable from a plugin carries the version (`PluginInput` has no version field; the SDK client's `app` namespace exposes only `log` and `agents` — verified live, `client.app.get()` does not exist).

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id. Todos then render inline in the subagent's session view (navigate via `session.child.next`), not the parent's. Empirically confirmed 2026-05-16 via subagent `ses_1d16d3bb4ffeOI5QUWZzBKDsSL`. -- Verified compatible with opencode v1.15.0 (audit 2026-05-16). `ProviderV2` hook gained an optional `ctx` arg we ignore; `McpStatus` expanded to 5 variants but `enabled: status === "connected"` in `mcp-bridge.ts` still collapses non-connected to `false` correctly. opencode's `tools` argument to `doStream` is intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. Re-audit at the next opencode minor bump. +- Verified compatible with **opencode v1.18.5** (audit 2026-07-26, against the published `@opencode-ai/plugin@1.18.5` + `@opencode-ai/sdk@1.18.5` type surface, plus a live `opencode run` turn on that binary). Nothing we depend on broke, because the plugin does not import opencode's types at all — `src/opencode-types.ts` is a hand-written structural mirror, so drift is silent and has to be audited deliberately. Findings worth remembering: + - The **v1 `Hooks` surface is unchanged** where we touch it: `config`, `provider: { id, models(provider, ctx) }`, `chat.params` (output still has `options: Record` at the top level, so the "do not pre-nest under providerID" gotcha still holds). + - A **v2 plugin API** now ships alongside it (`@opencode-ai/plugin/v2`, effect + promise flavors, `PluginContext` with `aisdk` / `catalog` / `agent` / `skill` / `command` hooks). It is additive; v1 `Plugin` is still the documented entry. Migration is optional — tracked in issue #24, do not start it casually. + - `PluginInput` gained `serverUrl: URL`, `$: BunShell`, `worktree`, `experimental_workspace`. Still **no version field** (see the diagnostics gotcha). + - `McpStatus` is still the same 5 variants, so `enabled: status === "connected"` in `mcp-bridge.ts` remains correct. + - The model schema (`sdk/v2` `Model`) gained optional `cost.tiers` (`{ tier: { type: "context", size } }`) and `cost.experimentalOver200K`, and `capabilities.interleaved` gained a `field: "reasoning"` variant. All optional, so our `defineModel` output still validates. Long-context pricing for the `1_000_000`-context entries is now expressible — issue #24. + - New hooks that overlap features we hand-rolled: `tool.definition` (description/param overlay), `experimental.session.compacting` + `experimental.compaction.autocontinue` (our `/compact` detection and auto-continue nudge), `experimental.chat.system.transform`, `chat.headers`, `permission.ask`. + - CLI flags changed: `opencode run` no longer accepts `-a` as shorthand for `--agent` (spell it out in smoke tests), and gained `--variant`, `--thinking`, `--auto`, `--pure`, `--fork`, `--attach`. + - Unchanged rationale: opencode's `tools` argument to `doStream` is still intentionally unused — Claude CLI only sees its own built-ins plus MCP servers bridged via `--mcp-config`, so opencode-native tools like `task_status` never reach the model and need no `mapTool` entry. + - Re-audit at the next opencode minor bump. The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. -- Startup diagnostics (`src/startup-diagnostics.ts`, roadmap #3): one `NOTICE: claude-code plugin ready` block emitted once per process from the `config` hook in `index.ts`, replacing the older "registered claude-code provider(s)" notices.

Headless `--print` Claude Code exposes no `Agent`/`Task` dispatch tool of its own (checked through CLI 2.1.211), so the `task` proxy is the only path — but the CLI *does* expose `TaskCreate`, a todo tool, and models resolve opencode's "call the task tool with subagent: X" mention hint straight to it: a todo appears, nothing runs, and the model narrates a successful dispatch. Since Task is proxied by default (v0.10.0) this is reachable without any config. Two spawn-time countermeasures, both required: `overlayTaskProxyDescription` in `proxy-mcp.ts` injects opencode's live `task` description (carrying the "Available agent types" list, so the model stops grepping configs to verify an agent exists) onto the proxy def, and `SUBAGENT_DISPATCH_HINT` goes into the appended system prompt naming `mcp__opencode_proxy__task` as the only dispatch path. The hint's ToolSearch line is load-bearing, not padding: harnesses that defer MCP tool schemas (opencode-dcp does) leave `mcp__opencode_proxy__task` invisible while `TaskCreate` stays visible, which is the worst case for this confusion — the maintainer hit exactly that during the v0.10.0 smoke test. `TASK_PROXY_NOTE` must keep describing the real deadline (60 min, `proxyToolTimeoutMs`) and `background` mode; jknlsn's original said 10 minutes, which predated the per-tool timeouts. Only wired into `doStream`'s spawn path — `doGenerate` has no proxy wiring at all, so it deliberately has no hint. Tests: `test-subagent-hint.ts`. - Claude CLI emits internal tools (`Agent`, `ToolSearch`, `AskFollowupQuestion`, `TaskList`, `TaskGet`, `TaskStop`) that have no opencode registry entry. They live in `CLAUDE_INTERNAL_TOOLS` in `src/tool-mapping.ts` and must be skipped, not forwarded. Forwarding them surfaces `⚙ invalid` tool rows in opencode. `TaskOutput` is the exception: it stays mapped to a `bash echo` so the result is visible. `TaskCreate` and `TaskUpdate` are NOT in this set — they route through the todo ledger (see next gotcha). - proxy-mcp `tools/call` responses MUST be MCP results (`{ result: { content, isError } }`), never JSON-RPC error envelopes. Claude CLI validates every `tools/call` response against the MCP result schema and rejects JSON-RPC errors as a "malformed result that failed schema validation" (seen live 2026-07-04 on broker timeouts/orphans — fixed post-0.9.2). All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart.

Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart.

Also lands roadmap #4: a worked `multistep` subagent example showing why `permission.todowrite: allow` is load-bearing, session.child.next navigation, and sqlite queries that prove the todos landed.

The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. +- Question proxy (absorbed from @jknlsn's `47501d0` in v0.12.0) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. @@ -95,9 +96,9 @@ Current state (refreshed 2026-07-26 after the fork/PR sweep): 1. ✅ Per-tool proxy timeouts — absorbed from @jknlsn's fork (`84f3db9`, authorship preserved) in v0.10.0: `proxyToolTimeoutMs` config, per-tool defaults (`task` 60 min), bash `input.timeout` floor.

Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. diff --git a/README.md b/README.md index e4d29c6..b14675f 100644 --- a/README.md +++ b/README.md @@ -456,7 +456,9 @@ Set `permissionMode: "plan"` to forward `--permission-mode plan` to Claude. The opencode ships a built-in `question` tool (`packages/opencode/src/tool/question.ts`) that renders a real TUI form with options and a custom-answer field — near-identical to Claude Code's `AskUserQuestion` (`multiSelect` → `multiple`). The plugin can route `AskUserQuestion` through it so the prompt becomes an actual form instead of plain text. Two modes: -### With `"Question"` in `proxyTools` (recommended on supported opencode) +### With `"Question"` in `proxyTools` (currently blocked upstream — leave it off) + +> **Known upstream breakage (opencode 1.15.x through at least 1.18.5).** opencode's `question` TUI form does not render, so the tool blocks until you interrupt the turn. This is not specific to this plugin: native providers hit it identically, and a `--pure` headless server drives the same question end to end successfully (`question.asked` → `GET /question` → `POST /question/{id}/reply` → tool completes), which isolates the fault to the TUI. Tracked upstream as [anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604) with fix [PR #36603](https://github.com/anomalyco/opencode/pull/36603) (unmerged). Until that lands, enabling `"Question"` trades the working fallback below for a hang. The instructions here describe the intended behavior for when it is fixed. Add `"Question"` to `proxyTools` and grant `permission.question: allow` to the calling agent. Claude's built-in `AskUserQuestion` is disabled via `--disallowedTools`, and the plugin exposes `mcp__opencode_proxy__question` in its place. The model calls the proxy, opencode renders the form, and the operator's answers come back as arrays of selected labels. On builds that lack the `question` registry entry the def is silently dropped at spawn (version gate), and the deny/markdown fallback below applies instead.

The `opencode` field in the startup block names the running version, so an audit starts by reading that. - `cwd` resolution at spawn must stay lazy. `opencodeProjectDirectory` captured from `PluginInput.directory` lives in `runtime-status.ts` and is consumed via `resolveSpawnCwd()` at spawn time only as a fallback when `process.cwd()` is unusable (`/`). Do NOT bake the captured value into `mergedOptions.cwd` during provider registration in `index.ts` — that freezes it at plugin init and breaks workspace switching mid-session. The v0.2.4 fix did exactly this and it shipped as the v0.4.21 regression report on issue #4. Tests live in `test-cwd-resolution.ts`. - `AskUserQuestion` is auto-denied in `controlRequestBehaviorForTool` (so the headless CLI can't self-answer an empty TTY) and rendered to the operator as markdown via `formatAskUserQuestion`. The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. +- **The `AskUserQuestion` fallback is currently dormant in headless mode.** Probed 2026-07-26 against Claude Code CLI **2.1.211**: the name is still *known* to the CLI (`--disallowedTools AskUserQuestion` validates silently, while a bogus name prints `matches no known tool`), but the tool is **not offered to the model** under `--print` — a direct "list every tool you can call" returns `Agent, Bash, Edit, Read, ReportFindings, Skill, ToolSearch, Workflow, Write`, and `ToolSearch select:AskUserQuestion` returns nothing. It reads as a TUI-only affordance the headless surface no longer presents. Consequence: with `Question` off (the default), the model has **no** question tool at all and can only ask in prose and end the turn — which is what the deny/markdown path produced anyway, so behavior is unchanged, but do not expect `formatAskUserQuestion` or the auto-continue latch to fire on this CLI. Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged). Re-test when that merges; until then do not promote `Question` toward the default list, and do not spend time debugging the proxy for this symptom. - Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`.

There is nothing to "switch to" — the plugin implements reasoning itself (reasoning variants → thinking keyword + `--thinking`/`--thinking-display` flags → `thinking_delta` forwarding), and any model defined with `reasoning: true` (including `claude-fable-5`) inherits the full path automatically.

These are exact ratios of published per-token price vs Haiku (input and output ratios coincide), so Fable/Mythos = 2× Opus. opencode has no native multiplier field, so the suffix is the only way it surfaces in the picker; it's display-only and model resolution still keys off `id`. `test-config-models.ts` asserts the suffixed names — update both if the format changes. - **ACTION DUE 2026-09-01: bump Sonnet 5 to standard pricing.** `claude-sonnet-5` currently ships introductory pricing ($2/M in, $10/M out, `sonnet5Cost`, multiplier 2×) which expires 2026-08-31.

The premiums that *do* exist are out of scope here: Fast Mode ($10/$50 on Opus 5/4.8, and this plugin never sends `speed: "fast"`), `inference_geo: "us"` (1.1×, not a CLI flag we pass), and partner-cloud regional endpoints (10%, not our path).

Same day, `claude-sonnet-4-20250514` / `claude-opus-4-20250514` retire (not registered here, but pass-through overrides could hit them). Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits. Confirmed failure mechanism: the 400 `Third-party apps now draw from your extra usage...` corresponds to a `rate_limit_event` with `{rateLimitType:"five_hour", overageStatus:"rejected", overageDisabledReason:"org_level_disabled"}` under OAuth subscription auth, so org-level overage/extra usage being disabled can reject requests that do not fit the remaining rolling window. URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata. Ignore it quietly; do not treat it as an error. - `WebSearch` with the default `"claude"` routing must NOT be forwarded as a tool-call part. opencode has no `WebSearch` registry entry, and (at least as of opencode v1.17.0) the AI SDK rejects unknown tool names with "Model tried to call unavailable tool" even when `providerExecuted: true` — users saw `⚙ invalid` rows on every CLI-internal web search (fixed after v0.8.0). `mapTool` returns `skip: true` for it, and both tool_use sites in `claude-code-language-model.ts` render the query as a `> **Web search:** …` text line instead (gated by `isWebSearchTool` + `isWebSearchHandledByCli` from `tool-mapping.ts`).

From 5fc08147f9ff1b3aa76c74a76fc91f48be9f91d2 Mon Sep 17 00:00:00 2001 From: Collie Tsai Date: Wed, 27 May 2026 02:22:16 +0800 Subject: [PATCH 186/211] Fix ExitPlanMode approval bridge Route ExitPlanMode through opencode's native `question` tool: render the plan, end the turn on `tool-calls`, then feed the operator's answer back to the CLI as the `tool_result` for the original ExitPlanMode tool_use. That tool_result is what actually unlocks plan mode; a "yes" typed as ordinary prose never does. Absorbed from CollieIsCute's fork (8c5b583) with authorship preserved, per their go-ahead on issue #21. Maintainer adaptations on top of the original commit: - Gated behind a new `planModeQuestion` option, default off. opencode's question form does not currently render (anomalyco/opencode#36604), so an ungated bridge would trade a working text prompt for a hang. All four ExitPlanMode sites keep the legacy text path in the `else`. - Gated on the live registry too (`isPlanModeQuestionActive`): emitting a `question` tool-call on a build without that entry renders as invalid and wedges the turn. - Gate resolved in the doStream/doGenerate prologue, since the branches run in a synchronous line handler and a reused process never reaches the spawn block. - `fetchLiveToolInfo` memoized via `liveToolInfoOnce()` so the plan-mode gate shares the single `tool.list()` fetch with the proxy overlays; unresolved fetches are not memoized. - Surfaced in the startup diagnostics block. - Dropped the fork's unrelated package.json changes (`prepare` script, tsx version), kept the test-script entry.

The deny message (`denyMessageForTool` / `ASK_USER_QUESTION_DENY_MESSAGE` in `claude-code-language-model.ts`) must tell the model to **stop and wait unconditionally** — end the turn, no more tools, no self-answer. Before v0.7.0 it offered an "if non-interactive, proceed with a reasonable guess" escape hatch; the model could not tell interactive opencode from a headless run and routinely took it, so questions appeared skipped (issue #8). Do not re-add a proceed-anyway clause to that message. Behavior is verified via `denyMessageForTool` in `test-ask-user-question.ts`; the full stop-the-turn flow needs a live opencode session where the model calls AskUserQuestion. Two reinforcing guards were added after v0.9.1: (1) the deny message explicitly states it is **not a cancellation** and forbids the model from saying the question was cancelled/skipped/declined — this kills the "the user cancelled, so I'll proceed" rationalization the model otherwise narrates; (2) a turn-local latch `AutoContinueState.sawAskUserQuestion`, set when `formatAskUserQuestion` renders, makes `shouldAutoContinueIncompleteTurn` return `{continue:false, reason:"question"}` for the rest of the turn. Without the latch, a short non-`?` trailing line after the question (e.g. "I'll go with the first option.") looked like an incomplete turn, and the auto-continue nudge made the model proceed with no operator input — the exact "I never interacted and it answered itself" symptom. Latch test in `test-auto-continue.ts`. - **The `AskUserQuestion` fallback is currently dormant in headless mode.** Probed 2026-07-26 against Claude Code CLI **2.1.211**: the name is still *known* to the CLI (`--disallowedTools AskUserQuestion` validates silently, while a bogus name prints `matches no known tool`), but the tool is **not offered to the model** under `--print` — a direct "list every tool you can call" returns `Agent, Bash, Edit, Read, ReportFindings, Skill, ToolSearch, Workflow, Write`, and `ToolSearch select:AskUserQuestion` returns nothing. It reads as a TUI-only affordance the headless surface no longer presents. Consequence: with `Question` off (the default), the model has **no** question tool at all and can only ask in prose and end the turn — which is what the deny/markdown path produced anyway, so behavior is unchanged, but do not expect `formatAskUserQuestion` or the auto-continue latch to fire on this CLI. Keep the machinery (older/newer CLIs and the interactive transport may still offer it); just do not treat "the fallback did not render" as a plugin bug without re-running the two probes above. Evidence is model self-report plus the ToolSearch miss, both on haiku. - **Question proxy is blocked upstream — leave it off.** Verified 2026-07-26 on opencode 1.18.5: the proxy delivers correctly but opencode's own `question` TUI form never renders, so an enabled `Question` costs you the working `AskUserQuestion` fallback and gives a silent hang the operator can only escape by interrupting. Proof it is not ours: (a) `github-copilot/gpt-5.5`, a native provider with the plugin nowhere in the path, fails identically (`Tool execution aborted`, `metadata.interrupted: true`, ~27 s); (b) the `part` table shows every `question` call `completed` through 2026-04-25 and every one since 2026-05-18 aborted, i.e. an opencode regression somewhere in v1.14.24…v1.15.5 (note `The user dismissed this question` is a *different*, healthy error — it means the form rendered); (c) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply` completes the tool with the answer and emits `question.replied`. So the server is fine and only the TUI render is broken. Upstream: anomalyco/opencode issue **#36604** (open) with fix **PR #36603** (`hydratePending()` at TUI bootstrap, open since 2026-07-13, unmerged). Re-test when that merges; until then do not promote `Question` toward the default list, and do not spend time debugging the proxy for this symptom. -- Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8. Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding both the task overlay and the question gate — do not add a second fetch. Both spawn-time only, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. +- Question proxy (absorbed from @jknlsn's `47501d0`, on master after 0.11.2) is the **opt-in alternative** to the deny/markdown path above, not a replacement for it. `"Question"` is deliberately NOT in `DEFAULT_PROXY_TOOL_NAMES` (`src/index.ts`) — enabling it disables Claude's built-in `AskUserQuestion` via `--disallowedTools` and swaps the unconditional stop-and-wait guarantee for an in-turn blocking form, which is a trade against issue #8.

(2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding the task overlay, the question gate and the plan-mode gate — do not add a second fetch; `liveToolInfoOnce()` memoizes it per model instance for exactly that reason, and deliberately does **not** memoize an unresolved fetch (`resolved: false`) so a not-yet-ready opencode server cannot disable every overlay for the life of the process. The proxy defs stay spawn-time, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. +- Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`.

Fields: plugin version, opencode version, `claudeCli` path+version, `cwd` **with the branch that won** (`configured` | `process` | `captured` | `unresolved` — `captured` is the issue-#4 macOS-GUI fingerprint), provider ids, accounts, `proxyTools`, enabled MCP servers, interactive-transport flag, `anthropicApiKeyInEnv`. It is fire-and-forget (`claude --version` is async, 5s timeout, cached) and every field is wrapped so diagnostics can never break provider registration. `describeSpawnCwd` intentionally mirrors `resolveSpawnCwd`'s priority order and a test asserts they never disagree — change both together. The MCP list is the **disk-only** merge (`mergeOpencodeMcp`, split out of `bridgeOpencodeMcp` so diagnostics never writes a scratch config): opencode's runtime status isn't settled at plugin init, so the per-turn overlay is deliberately not applied. The `opencode` field is resolved by `detectOpencodeVersion()`: the plugin runs inside opencode's process, so `process.execPath` **is** the opencode binary and ` --version` is the only reliable source (cached, 5s timeout, guarded on the basename containing "opencode" so a `bun run` from source reports "unknown" instead of Bun's version). It is only spawned when the plugin input and `OPENCODE_VERSION` gave us nothing. Do not "fix" this with an SDK call: re-verified on **1.18.5** that nothing on the plugin surface carries the version (`PluginInput` has no version field, the SDK client's `app` namespace is still only `log` + `agents`, and the server exposes no `/version` route — the route list in `sdk.gen.js` has none). To see the block: `OPENCODE_CLAUDE_CODE_LOG_FILE=1 opencode` then read `~/.local/share/opencode-claude-code/plugin.log` (the plugin logger is silent by default and does **not** write to opencode's own log).

Keep it opt-in until it has Task's mileage; the comment above the constant records why, so do not "tidy" it into the default list. Three invariants: (1) `--disallowedTools` is computed from the **post-filter** proxy list (`enrichedProxy`), never `resolvedProxy` — `filterQuestionProxyByOpencodeSupport` drops the def on opencode builds without a `question` registry entry, and computing from the pre-filter list would disable `AskUserQuestion` while its replacement is absent, leaving the model with no question path at all. (2) `QUESTION_PROXY_HINT` must name the FULL `mcp__opencode_proxy__question`: haiku strips the MCP prefix and calls bare `question`, which opencode renders as `⚙ invalid` (same near-miss family as TaskCreate vs the task proxy). (3) `question` gets a 30-min default in `PROXY_PER_TOOL_DEFAULT_TIMEOUT_MS` because it blocks on a human reading a form; the flat 10-min ceiling rejected calls mid-answer. `fetchLiveToolInfo` does ONE `client.tool.list()` fetch feeding the task overlay, the question gate and the plan-mode gate — do not add a second fetch; `liveToolInfoOnce()` memoizes it per model instance for exactly that reason, and deliberately does **not** memoize an unresolved fetch (`resolved: false`) so a not-yet-ready opencode server cannot disable every overlay for the life of the process. The proxy defs stay spawn-time, so a reused process keeps its defs. Verified live on opencode 1.18.5 (registry has `question`); a build lacking it takes the fallback silently, which the `question proxy version gate` log line makes visible. Tests: `test-proxy-mcp.ts`, `test-cli-args.ts`, `test-subagent-hint.ts`, `test-ask-user-question.ts`. - Plan-mode approval bridge (`src/plan-mode-question.ts`, absorbed from @CollieIsCute's `8c5b583` with authorship preserved, issue #21) is **opt-in via `planModeQuestion` and off by default**, for the same reason the question proxy is: it delivers through opencode's `question` form, and that form does not render (see the gotcha above), so an enabled bridge turns a working text prompt into a hang. Do not promote it to a default until #36603 merges and the round-trip is re-tested live. What it does when on: `ExitPlanMode` stops being rendered as `**Do you want to proceed with this plan?** (yes/no)` text and instead ends the turn on `tool-calls` with a synthetic `question` tool-call, then the operator's answer is turned back into a `tool_result` **for the original `ExitPlanMode` tool_use id** and sent as the entire next user message. That last part is the whole point of the port: Claude Code only leaves plan mode when it sees that `tool_result`, so a "yes" typed as ordinary prose never actually unlocks it. Invariants: (1) the gate is `isPlanModeQuestionActive` (config + live registry has `question` + not compaction) and it is resolved in the doStream/doGenerate **prologue**, not inside the stream body: the ExitPlanMode branches run in a synchronous line handler and a reused process never reaches the spawn block where the registry snapshot is otherwise taken. (2) Both transports have two ExitPlanMode sites each (partial-event `content_block_stop` and whole-`assistant`-message), so a change to one needs the same change to its twin; all four keep the legacy text path verbatim in the `else`. (3) `clearExitPlanModeQuestions(sk)` runs wherever `deleteClaudeSessionId`/`deleteActiveProcess` do, or a stale pending id outlives its session and the next answer is routed to a dead tool_use. (4) `finishReason` must be `tool-calls` (not the usual unconditional `stop`) when a question call was emitted, or opencode never runs the tool. Offline tests: `test-exit-plan-mode-question.ts`. The approval round-trip itself needs a live opencode session with `permissionMode: "plan"` and is **not verified**; it cannot be while the form is broken. +- Compress proxy tool (`src/compression-store.ts` + the `compress` def in `proxy-mcp.ts`, reimplemented from @flupkede's `4ac319f`/`5b4ee5d` on their unmerged `feature/compress-tool` branch, credit theirs). **Opt-in via `proxyTools: [..., "Compress"]`**, deliberately absent from `DEFAULT_PROXY_TOOL_NAMES` — it throws away the model's working context, which is not something to enable behind someone's back. It is the only proxy tool opencode never sees: `createProxyMcpServer`'s third argument is an interceptor map, and an intercepted `tools/call` is answered in-process (no broker entry, no deadline, no permission prompt). Five invariants: + 1. Interceptor results go out through `writeToolCallResult`, the single exit both the broker and interceptor paths share. The fork wrote a JSON-RPC error envelope on interceptor failure, which Claude CLI rejects as a malformed result (same trap as the proxy-mcp gotcha above). + 2. **The summary must survive `deleteClaudeSessionId()`** — the opposite of the plan-mode-question rule, and the fork got this exactly backwards: it cleared the summary there, and the reset path calls it, so the summary was wiped microseconds before the fresh spawn read it and the feature silently did nothing. `clearCompression` is called only from the `!hasPriorConversation` branch (a new opencode conversation), plus a 32-entry cap in the store. Regression test: "summary survives the session reset that the compress call triggers". + 3. The reset runs inside `doStream`'s `start()`, **after** `userMsg` and `includeHistoryContext` were resolved against the still-live session. That ordering is what makes it a real reset: `includeHistoryContext` stays false, so the fresh child gets this turn's message plus the summary in its system prompt and nothing else. Move the reset earlier and `compactConversationHistory` would replay the whole opencode conversation, which is the opposite of compressing. + 4. It is skipped when `hasMatchedPendingResults` — evicting a child whose tool results are arriving this turn would deliver a `tool_result` to a process that never issued the `tool_use`. The mark is not consumed, so it fires on the next turn instead. + 5. `CLAUDE_CLI_COMPRESS_NOTE` replaces `CLAUDE_CLI_CONTEXT_NOTE` only when `compress` is in the **post-overlay** proxy list (`enrichedProxy`), and it spells out the full `mcp__opencode_proxy__compress` for the same reason `QUESTION_PROXY_HINT` does. The default note still tells the model compress does not exist, which stays true for `doGenerate` (no proxy wiring) and the interactive transport (no proxy server). Tests: `test-compress-tool.ts`. The store/interceptor/prompt layers are covered offline; the end-to-end "model calls compress, next turn is fresh" round-trip is **not live-verified**. + - `ignoreAnthropicApiKey` (added 0.9.1, issue #9 secondary ask from @Aptul9): a stray `ANTHROPIC_API_KEY`/`ANTHROPIC_AUTH_TOKEN` in the env makes Claude Code authenticate with the key (pay-as-you-go Console billing) instead of the logged-in subscription, silently bypassing the Agent SDK plan credit. The flag strips both vars from the spawn env. The single strip point is `claudeSpawnEnv({ ignoreAnthropicApiKey })` in `session-manager.ts`; the headless `doGenerate`/`doStream` spawns and the interactive transport (`ClaudeSessionOptions.ignoreAnthropicApiKey` → inline env block in `claude-session-bun.ts`) all thread it through. Default off so deliberate API-key users are unaffected. `warnIfAnthropicApiKey` in `index.ts` logs a one-time startup warning whenever a key is present, regardless of the flag. Tests: `test-spawn-env.ts`. - Interactive transport (opt-in, `src/claude-session-bun.ts` + `src/claude-session-wrapper.ts`): `spawnInteractiveProcess` returns an `ActiveProcess`-shaped shim so doStream's line handler, session reuse, and eviction work unchanged. Key invariants: (1) doStream writes stream-json user envelopes to `stdin.write`; `decodeUserEnvelope` converts them to typed plain text — text blocks joined, `tool_result` rendered as labeled text, image/other blocks dropped with a logged warning (never paste base64 into a TTY). (2) The wrapper synthesizes the terminal `{type:"result"}` line; a turn with no terminal stop_reason (timeout/exit mid-turn) MUST stay `subtype: "error_during_execution", is_error: true` — do not "clean it up" to `end_turn`, that masks truncation from the user and from auto-continue. (3) The appended prompt reaches the TUI only via `--append-system-prompt-file` (built per spawn, unlinked on kill); interactive mode intentionally appends only this plugin's CLI note, AGENTS.md guidance, and continuation hint by default, not opencode's forwarded system prompt, because live testing showed that forwarded `extra` payload can trigger Claude Code's third-party-app usage gate on subscription accounts. `interactiveSystemPrompt: false` is diagnostic-only and drops even the plugin prompt. (4) There is no `can_use_tool` control channel in the TUI — permissions are pre-allowed via `--settings '{"permissions":{"allow":[...]}}'`: MCP wildcards always derived from the live bridge config, built-ins from `interactiveAllowTools` (default Bash/Edit/Write/Read/WebFetch). Do NOT pass `--permission-mode bypassPermissions` in interactive mode: Claude Code shows a manual safety confirmation and defaults to "No, exit", so pasted prompts can terminate the process. (5) The interactive spawn must use the configured `cliPath`, not plain `claude`; account providers rely on wrapper scripts like `~/.cache/opencode-claude-code-plugin/claude-` to strip `@account` model suffixes and set `CLAUDE_CONFIG_DIR`. The JSONL tail path must use the same `configDir` (`~/.claude-` for account providers), otherwise opencode hangs while Claude writes transcripts elsewhere. (6) The `Bun.Terminal` capability gate falls back to headless silently. (7) Compaction always takes the headless path. Turn timeout default is 30 min (`turnTimeoutMs` in `claude-session-bun.ts`). Offline tests: `test-claude-session-wrapper.ts`; live verification needs a Bun-run opencode with `interactive: true`. @@ -96,6 +103,7 @@ These rules supersede the older lifetime-cache and process-cleanup wording in th - Spawn-time cwd resolution (`resolveSpawnCwd`, captured-directory fallback): `test-cwd-resolution.ts`. - AskUserQuestion deny/stop behavior (`denyMessageForTool`, `isAskUserQuestionTool`): `test-ask-user-question.ts`. - Plan-mode approval bridge (`isPlanModeQuestionActive`, `createExitPlanModeQuestionCall`, `consumeExitPlanModeQuestionResult`): `test-exit-plan-mode-question.ts`. +- Compress tool (proxy interceptor path, compression store, compress vs default runtime note): `test-compress-tool.ts`. - Config-path model metadata injection (`configModelsForProvider`): `test-config-models.ts`. - Interactive transport (`decodeUserEnvelope`, `spawnInteractiveProcess` shim shape): `test-claude-session-wrapper.ts`. - Spawn-env API-key stripping (`claudeSpawnEnv` with/without `ignoreAnthropicApiKey`): `test-spawn-env.ts`. @@ -114,16 +122,10 @@ Current state (refreshed 2026-07-26 after the fork/PR sweep): Open work is tracked in issues: #22 (Sonnet 5 standard-pricing bump, merge just before 2026-09-01), #24 (opencode 1.18.5 surface: v2 plugin API, `tool.definition`, compaction hooks — its long-context-cost-tiers item is **closed as not-applicable**, see the pricing gotcha above), #26 (`proxyTools` allowlist-by-omission), #27 (`TaskOutput` shell interpolation). #20 (jknlsn absorption) is complete: timeouts + respawn in v0.10.0, task steering in v0.11.2, question proxy in v0.12.0. #21 (CollieIsCute absorption) is complete: flupkede's four items had already landed independently on 2026-05-18, so compare fork *contents*, not commit counts. -Fork sweep state (2026-08-19): nothing unabsorbed is left on `CollieIsCute/master` or `jknlsn/main`. `flupkede/feature/compress-tool` carried three commits that never reached their master; all three are now **evaluated**: - -- `60a6e9a` (AI-SDK-v4 image parts) is **absorbed** (cherry-picked, authorship preserved). `toImageBlock` accepted `type: "image"` parts but never read `part.image`, where v4 puts the binary, so pasted screenshots were silently dropped with a "file part without data" warning.

The reset waits if the incoming turn is carrying tool results for the running process. + +Without it, the appended system prompt tells the model that `compress` is unavailable and to ignore instructions that ask for it, which is the right answer when nothing implements it. + +Only those seven values are actually proxied; anything else you put in `proxyTools` is ignored. Proxying `Edit` also disables `MultiEdit` — opencode has no batched-edit equivalent, so Claude is forced to fan out into single `Edit` calls that each flow through the permission UI. The `"Question"` proxy is version-gated on opencode's built-in `question` tool: on builds that lack the registry entry the def is silently dropped (a forwarded call would otherwise render as `⚙ invalid`), so add it only on opencode versions that ship the `question` tool. Without `"Task"` in `proxyTools`, Claude's built-in `Agent` tool stays enabled and Claude orchestrates subagents internally with no opencode child-session visibility. To opt out of all proxying, including Task, use an explicit empty list: diff --git a/package.json b/package.json index 9397922..c87fbba 100644 --- a/package.json +++ b/package.json @@ -20,7 +20,7 @@ "build": "tsup", "dev": "tsup --watch", "typecheck": "tsc --noEmit", - "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts" + "test": "tsx --test test-bridge.ts test-broker.ts test-proxy-mcp.ts test-proxy-task.ts test-auto-continue.ts test-has-new-user-content.ts test-get-claude-user-message.ts test-logger.ts test-cli-args.ts test-session-manager.ts test-compaction-model.ts test-tool-mapping.ts test-cwd-resolution.ts test-todo-ledger.ts test-session-affinity.ts test-config-models.ts test-ask-user-question.ts test-claude-session-wrapper.ts test-spawn-env.ts test-respawn.ts test-startup-diagnostics.ts test-subagent-hint.ts test-exit-plan-mode-question.ts test-compress-tool.ts" }, "dependencies": { "@ai-sdk/provider": "^3.0.8", diff --git a/src/claude-code-language-model.ts b/src/claude-code-language-model.ts index 877e54f..b06da30 100644 --- a/src/claude-code-language-model.ts +++ b/src/claude-code-language-model.ts @@ -45,6 +45,12 @@ import { sessionKey, } from "./session-manager.js" import { spawnInteractiveProcess } from "./claude-session-wrapper.js" +import { + clearCompression, + consumeCompressionRestart, + getCompressionSummary, + storeCompressionSummary, +} from "./compression-store.js" import { log } from "./logger.js" import { detectCliVersion } from "./cli-version.js" import { @@ -58,6 +64,7 @@ import { type ProxyMcpServer, type ProxyToolCall, type ProxyToolDef, + type ProxyToolInterceptor, type ProxyToolResult, } from "./proxy-mcp.js" import { @@ -608,6 +615,22 @@ You are running via the Claude Code CLI (not a direct API call).

What they are waiting on now: -1. **Comment on upstream [anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604)** (open, fix [PR #36603](https://github.com/anomalyco/opencode/pull/36603) unmerged since 2026-07-13) with our question-form evidence, which is stronger than the report's: (a) the local DB brackets the regression to opencode v1.14.24…v1.15.5 — every `question` tool part is `completed` through 2026-04-25 and every one from 2026-05-18 on is `Tool execution aborted` with `metadata.interrupted: true`; (b) a `--pure` (no-plugin) headless `opencode serve` drives the whole server path green — tool blocks, `question.asked` publishes, `GET /question` lists it, `POST /question/{id}/reply {"answers":[["Alpha"]]}` completes the tool and emits `question.replied` — which isolates the fault to the TUI render step alone. The full write-up already exists as our issue #20 comment; adapt it rather than re-deriving. Re-test our question proxy when #36603 merges. -2. **Ping @jessielaf on issue #4** (cwd for the macOS desktop app). Last three comments are all Khalil's; the 2026-05-16 request to retest v0.4.21 has gone 71 days unanswered. Suggested wording: "v0.4.21+ has been out ~2.5 months, is workspace switching working for you now?" If no reply within a week, close #4 as resolved-pending-feedback (reopens on request) — that also retires roadmap item #5, which is speculative tier-two work nobody has confirmed is needed. +1. **[anomalyco/opencode#36604](https://github.com/anomalyco/opencode/issues/36604)** — our question-form evidence is posted. Two corrections to the older note: **PR #36603 is CLOSED unmerged**, so no fix is landing, and the issue is scoped to *detach + reattach* while our symptom happens with the TUI attached the whole time (the comment says so and offers to file separately if maintainers see it as distinct). Evidence posted: still reproducing on **1.18.18** (2026-08-19); 59 `completed` question parts between 2026-03-31 and 2026-04-25 vs essentially all aborted from 2026-05-18 on, bracketing the regression to v1.14.24…v1.15.5; the single post-boundary `completed` is our own headless `POST /question/{id}/reply` test, which is what isolates the fault to the TUI render step. **Re-test the `question` proxy and `planModeQuestion` when this moves** — both stay off until then. +2. **Issue #4** — @jessielaf pinged for a retest, with the startup-diagnostics `cwd` branch (`captured` is the fingerprint of this bug) as the thing to paste. Stated intent: close as resolved-pending-feedback if there is no reply in about a week, reopening on request. That also retires roadmap item #5.

Fable 5 is included free on plans only through 2026-06-22; after that it needs usage credits.

URL redaction was tested and reverted; the opencode repo URL is not the trigger. Interactive mitigation: live bisection showed this plugin's own CLI/AGENTS/continuation prompt succeeds, while opencode's forwarded system prompt payload can trip the usage gate on constrained subscription accounts. Interactive mode therefore intentionally omits the forwarded opencode system prompt by default. Real account-side fixes remain: enable overage/add extra usage, wait for the 5-hour window reset, switch account/org/plan, or use API-key auth. - `signature_delta` is expected encrypted thinking metadata.

The CLI always emits a `stop_reason`, and `shouldAutoContinueIncompleteTurn` treats any `stop_reason` as authoritative (v0.4.17), so the keyword heuristic below that guard — `looksLikeFinalAnswer` / `looksLikeQuestion` / `looksLikeBlocker` and the whole v0.4.10–v0.4.15 idiom list — is dead code in practice, and `autoContinueIncompleteTurns: "smart"` behaves as `off`. @JWebCoder's PR #15 diagnosed this correctly; it was closed because the remedy (delete the guard) promotes the regex back to the deciding vote on every turn, which is exactly what v0.4.17 removed, and it also carried a `package-lock.json` this repo deliberately does not have. The narrow change worth making, if anyone picks it up: let `max_tokens` fall through to the heuristic, since truncation is the one stop reason that does not mean "finished", while `end_turn`/`stop_sequence` stay authoritative.

A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. - Subagent todos require `permission: { todowrite: "allow" }` on the subagent definition. opencode's `task.ts:197` injects `todowrite: false` into the tools dict for subagents that don't have the rule, so the ledger's synthetic todowrites surface as `⚙ invalid` in the subagent's stream. Built-in `general` denies todowrite by default (`agent.ts:171`); custom subagents must grant it explicitly. When permission is granted, the data flow is fully verifiable in `~/.local/share/opencode/opencode.db`: rows land in the `todo` table and parts with `tool="todowrite"` appear in the `part` table for the subagent's session id.

Rejected requests ended the response but left the connection usable. A peer could declare a large Content-Length, send one byte, take the 401 and hold the socket -- and server.close() does not reap connections that are still sending, so shutdown blocked behind an unauthenticated caller for Node's five-minute request timeout. All five reject paths now go through one helper that sets Connection: close and tears the socket down once the response has flushed. The new regression deliberately never finishes its body. An earlier version of the suite would have masked this, because it destroyed the socket client-side as soon as the response arrived -- exactly the cleanup the server must not depend on. Mutation-checked: with only the Connection: close and teardown removed it fails at 4s instead of passing at 4ms. The 0600 mode assertion is now POSIX-gated. Node implements no owner/group/other mode bits on Windows, where it commonly reads back 0666 and confidentiality rests on the inherited ACL of os.tmpdir() instead, so asserting it there tested nothing and claiming it in the PR would have promised a guarantee this patch does not provide. Comments at the Host and Origin guards were corrected too: the exact-Host check blocks DNS rebinding, NOT a page posting directly to the loopback port, which sends exactly the expected Host. --- src/proxy-mcp.ts | 52 +++++++++++++++++++++++++++++++++------------- test-proxy-mcp.ts | 53 +++++++++++++++++++++++++++++++++++++++++++++-- 2 files changed, 89 insertions(+), 16 deletions(-) diff --git a/src/proxy-mcp.ts b/src/proxy-mcp.ts index cf3f709..a21f253 100644 --- a/src/proxy-mcp.ts +++ b/src/proxy-mcp.ts @@ -616,27 +616,53 @@ export async function createProxyMcpServer( return crypto.timingSafeEqual(candidate, expectedAuth) } + /** + * Reject a request without leaving the connection usable. + * + * Ending the response alone is not enough.

All three error paths in `src/proxy-mcp.ts` now return results with `isError: true`: unknown tool, `result.kind === "error"` (merged into the success path), and the outer `catch` when `requestMethod === "tools/call"`. Non-`tools/call` methods (initialize, tools/list) and unparseable requests still use JSON-RPC errors, which is spec-correct. `requestId`/`requestMethod` are hoisted above the try so the catch can echo them — do not regress to `id: null`. Tests: `test-proxy-mcp.ts`. +- **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (0.13.2) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open. Three consequences to remember: (1) `authToken` must never be logged or put in the URL — the log line in `reject()` deliberately reports only `hasAuthorization`, never values; (2) the Origin and Content-Type guards are **measured properties of the client we spawn**, not spec guarantees, so a future Claude CLI that starts sending an `Origin` would 403 every call — that is exactly why `reject()` logs a reason at NOTICE; (3) anything in-repo that drives the endpoint over HTTP has to authenticate, which is why `test-proxy-mcp.ts` has `authedPost` and `test-compress-tool.ts` threads `srv.authToken`. Live-verified end to end on **Claude Code 2.1.226** (2026-08-20): real CLI, real `--mcp-config`, proxy call received and answered. Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. diff --git a/src/proxy-mcp.ts b/src/proxy-mcp.ts index a21f253..91efbd7 100644 --- a/src/proxy-mcp.ts +++ b/src/proxy-mcp.ts @@ -630,7 +630,24 @@ export async function createProxyMcpServer( * destroying the socket on `finish` covers the case where the peer never * finishes its body. */ - function reject(req: IncomingMessage, res: ServerResponse, statusCode: number): void { + function reject( + req: IncomingMessage, + res: ServerResponse, + statusCode: number, + reason: string, + ): void { + // Every guard below is a measured property of the client we spawn, not a + // guarantee about future ones.

Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded.

Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. +- **The proxy MCP endpoint is authenticated.** It executes Bash/Edit/Write through opencode's executor, so before @willmcginnis's PR #28 (fixed in 0.13.2, disclosed as **GHSA-3mxm-w7gf-3c5x**, High/CVSS 7.5 `AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H`, affecting >= 0.1.3 < 0.13.2; a CVE was requested from GitHub's CNA on 2026-08-20 and was still unassigned at that point — check `gh api /repos/khalilgharbaoui/opencode-claude-code-plugin/security-advisories/GHSA-3mxm-w7gf-3c5x --jq .cve_id` and, once it lands, add it to the README security section and the v0.13.2 release notes) any local process could POST to the loopback port and get arbitrary command execution, and a web page could do it blind via a `text/plain` CORS simple request. `createProxyMcpServer` now mints a 256-bit bearer token per server, hands it to Claude in the `headers` block of the generated `--mcp-config` (that file is `0600`, which is now load-bearing), and rejects every request that fails one of four guards, in this order: `Host` must equal the bound `127.0.0.1:` authority (DNS rebinding), `Origin` must be absent, `Content-Type` must be `application/json` (forces a preflight that then fails, closing the simple-request hole), and the bearer token must match under `timingSafeEqual`. All four run **before** `readBody`, so an unauthenticated peer cannot stream a body into memory, and `reject()` sets `Connection: close` and destroys the socket so a slow unauthenticated body cannot hold `server.close()` open.

Do not "simplify" a guard without re-running that check; the unit tests cannot see a client-side header change. **Upgrading does not patch a running opencode**: the plugin is loaded once at process start, so every opencode left open from before the upgrade keeps serving an unauthenticated proxy port until it is restarted. Observed on the maintainer's own machine on 2026-08-20, where three sessions from Aug 5 and Aug 18 still answered `POST /mcp` with 200 and 145-byte MCP configs (no `headers` block) while the freshly started one answered 401 with a 272-byte config. That probe (`lsof -nP -iTCP -sTCP:LISTEN | grep opencode`, then an unauthenticated `initialize`, 401 = patched, 200 = stale) is the check to run after any security release, and it is in the README security section for users. - Proxy call deadlines are per-tool, not flat. `resolveProxyCallTimeoutMs(toolName, input, overrides)` in `src/proxy-mcp.ts` is the single resolver consumed by BOTH the proxy-mcp HTTP handler (`:478` area) and the broker (`queuePendingProxyCall`); the two layers must never race on different values, so any new timeout site must call it too. Layering: flat 10-min default → per-tool default (`task` 60 min) → `proxyToolTimeoutMs` config override (case-insensitive) → for `bash` only, `max(resolved, input.timeout)` so the proxy never undercuts a build the caller explicitly asked to run long (the bash def advertises a `timeout` field; ignoring it forced a model to `nohup` xcodebuild and poll a log file — live ses_0cfc0da6, 2026-07-05). `buildProxyTimeoutError(toolName, ms)` keeps the catch-block substrings (`"timed out after"` + `"waiting for opencode to resolve"`) so the expected-cleanup classifier at the proxy-mcp catch still demotes to NOTICE; the `task` variant appends a "do not schedule a wake-up, that does not apply here" note. That note is load-bearing: when a Task timeout fires the subagent may still be running but its result is unreachable (the late broker resolve finds the entry already deleted), and without the note the model "schedules a wake-up" — a real Claude Code affordance that cannot fire in headless/proxy mode — and ends its turn, so the operator must manually nudge "please check now, it seems the task succeeded" (same live session). The flat `PROXY_CALL_TIMEOUT_MS` constant is gone; do not reintroduce it. The one remaining flat value is `resolveProxyClientCeilingMs(overrides)` — the `timeout` written into Claude's `--mcp-config` entry for the proxy server (without it Claude's remote-HTTP MCP client aborts at its 60-second default, @broskees PR #18); it tracks the max of all effective deadlines so the client never gives up before the broker. Config is read once at opencode startup like the rest of the proxy block, so `proxyToolTimeoutMs` changes need a full restart. Tests: `test-proxy-mcp.ts`, `test-broker.ts`. - Reused-process start watchdog. A reused `claude --print` child can go silent on stdout after a fresh-turn envelope write — seen after a very long proxy-blocked `task` call resumed successfully (the per-tool timeout fix let the block return instead of ending the turn, which is what previously masked this). The doStream `armStartWatchdog()` (`src/claude-code-language-model.ts`, fired only on the fresh-turn write path) complements the existing inactivity watchdog, which explicitly skips the pre-content gap (`if (!hasReceivedContent) return`). On first fire (default 90s, env `CLAUDE_CODE_START_WATCHDOG_MS`) it respawns the child via `respawnActiveProcess` (`src/session-manager.ts`) — which kills the wedged child but REUSES its proxy server, system-prompt file, and mcp hash (their handles are baked into the original `cliArgs`) and appends `--resume` so the conversation resumes transparently (`--session-id` would be rejected with "already in use" once a transcript exists — see the `--resume` gotcha; adapted during absorption on top of PR #18). The old child's exit handler is silenced (`removeAllListeners("exit")`) before kill so it doesn't close the reused proxy. A second fire (respawn also silent) ends the turn with an error + `deleteActiveProcess` so the next opencode turn spawns fresh. `cliArgs` is hoisted to doStream scope so the watchdog (which lives outside the non-interactive `else` spawn block) can see it. The tool-result turn path (`hasMatchedPendingResults`) does NOT arm the watchdog — no envelope is written there (the proxy resolution unblocks claude directly). Tests: `test-respawn.ts`. - Todo ledger translates Claude CLI's granular `TaskCreate`/`TaskUpdate` family into opencode's full-list `todowrite` so the opencode todo panel populates during multi-step Claude work. State lives in `src/todo-ledger.ts`, keyed by Claude CLI session id, cleared via `clearLedger` from `deleteClaudeSessionId` in `session-manager.ts`. TaskCreate stashes pending by `tool_use_id` on tool_use and commits on tool_result (parsed via `/Task\s*#?\s*(\d+)\s+created/i`); TaskUpdate mutates in place. Without `sessionId` in `MapToolOptions`, both fall back to `{skip: true}` to preserve safety for callers that haven't been threaded. Tests live in `test-todo-ledger.ts` and `test-tool-mapping.ts`; live UI verification requires a fresh opencode session with a multi-step Claude task. diff --git a/README.md b/README.md index b95e785..e0820e6 100644 --- a/README.md +++ b/README.md @@ -305,6 +305,16 @@ The proxy is a small HTTP MCP server on an ephemeral loopback port, and calling **Upgrade if you are on 0.13.1 or earlier.** Before this, any local process could post to that port and execute commands as you, and a web page you visited could do the same blind, without reading the response.
