Release v0.8.0

[0.8.0] — 2026-06-08

agentlift import — read a live agent back into the folder (the inverse of deploy).
A new reverse pipeline reconstructs a neutral .managed-agents/ folder from a live managed
runtime, so a runtime now round-trips both ways — and migration between runtimes falls out
for free. Anthropic import is full; AWS Bedrock import covers the config-only Harness.

Migrate by pairing import with deploy — the folder is the neutral pivot:

# Anthropic → AWS Bedrock
agentlift import anthropic ./agent
agentlift deploy ./agent --target bedrock --mode harness
# …and back
agentlift import bedrock ./agent --harness-name my-agent --bedrock-region us-west-2
agentlift deploy ./agent

Added

• agentlift import <anthropic|bedrock> <out> [--agent N …] [--mode harness] [--harness-id|--harness-name] [--bedrock-region R] [--dry-run] —
  a read-only command (never creates/updates/archives). It fetches the live agent, maps it to
  a neutral project, writes the folder, and self-verifies by re-running the real parse + plan
  (prints Round-trip OK only if the result is deployable again). --dry-run is the import
  analogue of plan (prints the mapping + diagnostics, writes nothing).
• Anthropic import (full). agents.list/agents.retrieve + skills.versions.download
  recover system/description/model, built-in tools with :ask/:allow permission policies,
  URL MCP servers + per-server tool filters, custom skill content, and a coordinator's
  subagents (roster ids resolved to names; selecting a coordinator pulls its subagents into
  the closure automatically). Skills/MCP used identically by >1 agent are hoisted to shared/
  (skills keyed by content hash, MCP by full identity) — the inverse of the planner's dedup.
• Bedrock Harness import (import bedrock --mode harness). get_harness + S3 skill bundles,
  with a reverse model-map (regional inference profile → folder Claude id, e.g.
  eu.anthropic.claude-haiku-4-5-20251001-v1:0 → claude-haiku-4-5), agentCoreBrowser → web
  tools, agentCoreCodeInterpreter → sandbox builtins, and remote_mcp → URL MCP. Single-agent
  by nature, so an import never produces subagents.
• New modules, mirroring the deploy pipeline in reverse (pure core + thin network edge):
  import_model.py, importer.py (inverse of planner.py), folder_writer.py (inverse of
  parser.py) — all pure and offline-tested — plus the network edges anthropic_source.py and
  harness_source.py.
• End-to-end tests. tests/test_importer.py (the mapping contract), tests/test_import_roundtrip.py
  (provider responses → folder → real parser → real planner, including subagent delegation with
  shared and custom skills and MCP servers), tests/test_import_source.py (fetch wiring via
  fake clients, no network), tests/test_cli_import.py, and a gated read-only live test
  tests/live/test_import_anthropic.py (AGENTLIFT_LIVE_IMPORT=1).
• Docs. New docs/import.md; import notes added across the convention,
  how-it-works, provider-matrix, anthropic-mapping, deploy-bedrock, deploying, and limitations docs.

Notes / honest boundaries

• The Bedrock Runtime is not importable. A Runtime bakes its agent definition into an opaque
  ARM64 container image (GetAgentRuntime returns only a containerUri), so it can't be read
  back; import bedrock --mode runtime refuses with that reason. This is the import analogue of
  the deploy-time /invocations trace boundary. Google/OpenAI import is not implemented yet.
• Four one-way losses, each surfaced as a Diagnostic (never silent): knowledge inlining is
  one-way (it stays in the prompt body on import); custom tools / harness inline functions are
  dropped; MCP auth values are provider-side, so only the header/env-var name is recovered;
  Anthropic first-party (type: anthropic) skills are referenced by id with no downloadable content.
• One wire-format item pending a live download: the Anthropic skill-bundle archive layout (a
  zip whose members carry the <name>/… prefix) is the documented shape but is not yet confirmed
  against a live download — the unpack is defensive and emits import.skill_archive_shape if the
  payload is anything else (the repo's confirm-live-before-trusting rule).

Release v0.7.0

[0.7.0] — 2026-06-05

AWS Bedrock AgentCore Runtime is now a live multi-agent hosted deploy (Stage 2). Both
AgentCore primitives are live-verified: the single-agent Harness (0.6.0) and now the
custom-container Runtime. --mode auto routes a single agent → Harness and a multi-agent
team → Runtime; mapping stays Claude-native (no remap), with wire-shape receipts on Nova
because Claude inference on Bedrock is a one-time per-account entitlement (Gate A), not a code gap.

Added

• --mode runtime — live hosted multi-agent deploy. agentlift deploy --target bedrock --mode runtime builds the ARM64 Strands/AgentCore container, creates the ECR repo + logs in +
  docker buildx --platform linux/arm64 --push, calls CreateAgentRuntime (PUBLIC network,
  HTTP serverProtocol, IAM-only — no JWT authorizer), polls READY, writes
  .agentlift-bedrock.json, and InvokeAgentRuntime. Gated by _RUNTIME_LIVE_VERIFIED
  (now True) — a bare hosted create refused until a committed receipt.
• Subagent delegation live-proven on a Nova receipt (tests/live/receipts/20260605-134012-runtime-bedrock):
  a coordinator + 2 specialists where create + agent + delegation are all PASS-EXERCISED (the
  coordinator's top-level trace named both specialists). A single-agent smoke
  (20260605-133821-runtime-bedrock) separately got remote MCP PASS-EXERCISED (an objective
  root-level docs_read_wiki_structure DeepWiki call).
• Top-level tool-call trace in the generated handler — returns {result, tool_calls?} where
  tool_calls is read from AgentResult.metrics.tool_metrics (fail-open: trace extraction never
  breaks the invocation), so the deploy receipt can prove delegation objectively.
• The boto3 (bedrock) optional dependency now also covers the Runtime hosted deploy.

Changed

• The bare agentlift deploy --target bedrock --mode runtime now deploys live instead of
  refusing; --build-only still emits just the ARM64 container artifact (its NOTES.txt now
  points at the live hosted-create path).
• .agentlift-bedrock.json (the Runtime lock) is now live-writing (spec hash → create/update/skip).

Notes / honest boundaries

• The /invocations boundary. InvokeAgentRuntime returns the container's app-defined JSON
  body, not a tool-event stream. So subagent delegation and root-level skill/MCP calls are
  objective (PASS-EXERCISED), while a specialist's nested skill/MCP calls don't cross the
  boundary → PASS-WIRED + text-corroborated (the runtime analogue of the Google
  AgentTool→stream_query grounding-metadata caveat).
• MCP per-tool-filter limitation narrowed. The unenforced-allowedTools limitation applies only
  to the direct remote_mcp attachment path; for AgentCore Gateway-fronted MCP, tool scoping
  is enforced server-side at the Gateway/Policy layer (AWS-documented; agentlift has not yet
  live-verified that path).
• Runtime execution role needs: bedrock-agentcore.amazonaws.com trust (aws:SourceAccount
  condition — not a region-locked SourceArn), ECR pull, bedrock:InvokeModel, CloudWatch Logs.

Release v0.6.0

0.6.0 — 2026-06-05

AWS Bedrock AgentCore joins the deploy targets, with two primitives behind --mode
(auto picks the least-powerful one that preserves the folder's semantics — never a silent
downgrade). Both are Claude-native — no Gemini-style model remap; a folder's claude-*
maps to its regional Bedrock inference profile directly.

Added

• --mode harness — live single-agent deploy to a managed AgentCore Harness (config-only,
  IAM-only, no container). One agent with its skills, remote MCP, sandbox, and browser,
  6/6 live-verified end-to-end by a committed Nova receipt
  (tests/live/receipts/20260605-121525-harness-bedrock): agent + base-session sandbox
  (shell) + remote MCP (docs_read_wiki_structure, surfaced as <server>_<tool>) + an
  S3-loaded skill (skills[].s3.uri) + agentcore_browser.

  • Skills upload to $AGENTLIFT_BEDROCK_S3_BUCKET and attach via skills[].s3.uri; the
    execution role needs s3:ListBucket + s3:GetObject.
  • Idempotent via .agentlift-harness.json (spec hash → create/update/skip); a since-deleted
    clientToken triggers a retry without it.

• --mode runtime --build-only — compiles a Strands package + a complete deployable
  ARM64 AgentCore Runtime container (image + Dockerfile + NOTES.txt runbook) for the
  multi-agent path.

• audit and export bedrock-strands cover the new target; agentlift plan --target bedrock [--mode auto|harness|runtime].

• CHANGELOG.md; a CI doc-link guard (tests/test_doc_links.py) that checks every relative
  path + intra-repo anchor in the README and docs.

• Google built-in web tools (--target google): web_search → Google Search grounding and
  web_fetch → URL Context, each lowered as a wrapped single-tool ADK sub-agent; exercised on a
  separate live Google deploy.

• Claude-on-Vertex — an offline-verified spike (experiments/claude-on-vertex/): ADK resolves
  Claude on Vertex and the mixed-model shape composes. Not shipped — a Claude --google-model is
  refused (no live receipt yet); folder Claude models still map to Gemini on Google.

Changed

• README restructured (≈494 → ≈214 lines): big-picture-first, with a one-glance provider
  snapshot (AWS Bedrock now first-class), the deep capability matrix moved to
  docs/provider-matrix.md, and consistent collapsibles. Updated hero graphic (four backends).
• Provider docs reconciled to the live-verified state (docs/provider-matrix.md,
  deploy-bedrock.md, tested-platforms.md, limitations.md).

Notes / known limits

• A multi-agent team (subagents) routes to the Runtime; the harness is single-agent.
  The Runtime's hosted create (create_agent_runtime) is build-only here (not yet
  live-verified) — a hosted multi-agent deploy is the next milestone.
• The AgentCore Harness feature is in AWS public preview. Claude inference runs in the
  harness but is gated by the per-account Anthropic use-case entitlement (Gate A), which is
  eventually-consistent — so the model-agnostic wire-shape receipt was captured on Amazon Nova.
• Per-tool MCP allowedTools narrowing is not enforced on the harness preview (a restrictive
  allowlist suppresses MCP tool surfacing), so agentlift emits none and surfaces a diagnostic.
• :ask is not enforced on either Bedrock primitive (no interactive approval channel).

0.5.0 — 2026-06-04

Added

• Google Vertex AI Agent Engine deploy (--target google) gains full Skills (embedded
  in the source package, loaded via ADK load_skill_from_dir) and URL MCP (McpToolset +
  tool_filter, inline auth resolved into Agent Engine env_vars).
• 6/6 live coverage matrix — one neutral fixture deployed and queried on both Anthropic
  and Google, all six portability dimensions (agents · subagents · shared/individual MCP ·
  shared/individual skill) EXERCISED server-side, with committed receipts.
• docs/provider-matrix.md — the canonical cell-by-cell capability matrix.
