All 3 verified against current code and the actual failure modes before fixing, not applied blindly from the bot's suggestion text. 1. getLLMDecisionWithVision: the Anthropic image block declared media_type: 'image/png' while the screenshot is captured as JPEG (page.screenshot({ type: 'jpeg' })). This is the exact mismatch already disclosed (by me) in the PR's "Note to Reviewers" before CodeRabbit caught it independently, confirmed against Anthropic's own docs that a media_type mismatch can 400 before the forced tool call ever runs. Fixed to 'image/jpeg'. The identical bug also exists in the untouched openai branch's `data:image/png;base64,...` URL - left as-is and flagged, not silently fixed, since that branch is explicitly out of this PR's scope. 2. parseSearchIntent: the validation `!intent.searchQuery || !intent.extractionGoal` is a truthiness check, not a type check. Since callAnthropicWithTool returns raw tool_use.input with no strict-mode validation, a non-string value (e.g. an object) passes this guard, and downstream `encodeURIComponent(query)` (workflowEnricher.ts, both performDuckDuckGoSearch and performDuckDuckGoMultiSearch) silently turns it into the literal string "[object Object]" as a search query. Verified this exact call chain before fixing. Replaced with a guard that requires searchQuery/extractionGoal to be non-blank strings and limit (when present) to be an integer. Applied to both the anthropic branch's copy of this check AND the shared ollama/openai JSON-parsing branch's identical copy, per CodeRabbit's own comment text ("Apply the same validation to the JSON parsing branch") - not my own scope expansion, the finding explicitly asked for both. 3. selectMultipleUrlsFromResults: the per-index collection loop had no cap on `result.length`, so a tool response returning more valid, unique-domain indices than the caller's `maxSites`/`cap` would collect all of them instead of stopping at cap - e.g. 5 valid indices with cap=4 would produce 5 downstream workflows instead of 4. Added `if (result.length >= cap) break;` at the top of the loop, matching CodeRabbit's exact suggested diff. This identical bug also exists, unchanged, in the original shared-tail copy of this same loop (which predates this PR and serves ollama/openai) - CodeRabbit's finding did not ask for that copy to be fixed too, so it's flagged, not touched. Verified: full project tsc --noEmit clean. A targeted test reproduced each finding's exact described failure mode against the pre-fix code path conceptually and confirmed the fix resolves it: searchQuery as an object, as an array, as an empty/whitespace string, limit as a fraction, and limit as a numeric string are all now correctly rejected (falling back to the existing regex heuristic, not silently proceeding); valid inputs including an omitted limit still succeed unchanged; 5 valid unique-domain indices against cap=4 now correctly returns exactly 4, and a below-cap selection is unaffected. Re-ran the full 9-site fallback regression afterward to confirm the shared-code changes (finding getmaxun#2) didn't affect any of the other 8 sites.

…un#1189 Reject __proto__/constructor/prototype field names and use a null-prototype target in filterFieldsByIntent's Anthropic branch to prevent prototype pollution from untrusted tool output. Add explicit type validation for first/second/reason/limit in getLLMDecisionWithVision's Anthropic branch, since input_schema isn't runtime-enforced without strict mode. Reject non-positive and non-safe-integer limit values in both parseSearchIntent validation blocks (Anthropic branch and shared ollama/openai tail).

@hmhngx looks good. Before we merge:

Introduces a typed helper for calling Anthropic with tool_choice forced to a single named tool, returning tool_use.input directly instead of parsing JSON out of a free-form text completion. Foundational piece for migrating the 9 Anthropic call sites in workflowEnricher.ts off regex/JSON.parse (getmaxun#1178). Not wired into any call site yet - this commit only adds the helper. None of the tools this helper is designed for use strict: true, so tool_use.input is never validated server-side against the schema; call sites must keep their own field-level checks (throw / typeof guard / inline fallback) on the returned value. tool_choice sets disable_parallel_tool_use: true so the forced tool cannot be invoked more than once per turn.
…ection Migrates the anthropic branch of getLLMDecisionWithVision (site getmaxun#1 of 9, issue getmaxun#1178) off regex fence-stripping + JSON.parse onto callAnthropicWithTool with a forced select_group_candidates tool. - Adds server/src/sdk/anthropicTools.ts with selectGroupCandidatesTool - first of the 9 tool definitions, will grow with each subsequent site. - The anthropic branch now returns directly from inside the if/else chain once its decision is built, instead of falling through to the shared regex/JSON.parse tail that ollama and openai still use unchanged. - Preserves the vision content shape exactly (image block + text block, still carrying the pre-existing jpeg-captured/media_type:'image/png' mismatch at screenshot capture - not touched, out of scope for this PR). - Preserves the missing `temperature` param (this was the one call site of the 9 that never sent it) and the existing claude-3-5-sonnet-20241022 default (stale/retired model ID - also out of scope, filed separately). - fallbackHeuristicDecision is unchanged and still triggered by the same outer catch on any thrown error from the new call. Verified: full project tsc --noEmit clean; a mocked runtime check (ts-node, monkey-patched callAnthropicWithTool) confirmed the helper receives the exact expected tool/model/maxTokens/apiKey/userMessage array and no temperature field, that a successful decision flows correctly through parseGroupCandidates/buildDecisionFromCandidates, and that a thrown error still correctly falls back to the existing fallbackHeuristicDecision.
Migrates the anthropic branch of generateFieldLabelsBatch (site getmaxun#2 of 9, issue getmaxun#1178) off regex fence-stripping + JSON.parse onto callAnthropicWithTool with a forced assign_field_labels tool. - Appends assignFieldLabelsTool to server/src/sdk/anthropicTools.ts. - Typed as callAnthropicWithTool<any>, deliberately - the original code's defensive `if (parsedResponse.fieldLabels) {...} else { labelMapping = parsedResponse }` fallback exists precisely because the response shape isn't guaranteed even under the tool's required schema (non-strict tool, no server-side validation). Typing this call more narrowly would let TypeScript claim decision.fieldLabels is always defined when it isn't, silently defeating the exact check it's supposed to preserve. Ported that defensive block and the missingLabels identity-fill logic verbatim, just reading from `decision` instead of `parsedResponse`. - Anthropic branch now returns directly, same early-return pattern as site getmaxun#1; the shared regex/JSON.parse tail is untouched and still serves ollama/openai unchanged. - Preserves max_tokens 2048 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node, monkey-patched callAnthropicWithTool) covered three scenarios: wrapped {fieldLabels:{...}} success, a flat (unwrapped) success shape to prove the defensive else-branch genuinely still fires and the missingLabels fill-in still runs on top of it, and a thrown error correctly falling back to full identity-mapping via generateFieldLabelsBatch's own catch. Also asserted the exact opts reaching the helper (tool identity, model, maxTokens, temperature, apiKey, plain-string userMessage, non-empty system prompt).
Migrates the anthropic branch of filterFieldsByIntent (site getmaxun#3 of 9, issue getmaxun#1178) off regex fence-stripping + JSON.parse onto callAnthropicWithTool with a forced filter_fields_by_intent tool. - Appends filterFieldsByIntentTool to server/src/sdk/anthropicTools.ts. required: ['selectedFields','confidence','reasoning'] matches the sibling Ollama jsonSchema exactly - no precedent divergence here. - Typed as callAnthropicWithTool<any>, same rationale as site getmaxun#2: this function has HARD throws on invalid shape (`!Array.isArray(selectedFields)`, confidence type/range check) that are load-bearing for the fallback mechanism. A narrower generic type would let TypeScript claim those checks are unreachable when they are not actually guaranteed at runtime (non-strict tool, no server-side validation). Ported both throws and the unknown-field-name warn-and-skip loop verbatim, reading from `decision` instead of `filterResult`. - Anthropic branch returns directly; shared regex/JSON.parse tail untouched, still serves ollama/openai. - Preserves max_tokens 1024 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 7 scenarios: valid high-confidence success, valid low-confidence (needsUserConfirmation flips true), non-array selectedFields correctly throws and falls back to the full labeledFields object, out-of-range confidence correctly throws and falls back, wrong-type confidence correctly throws and falls back, an unknown field name in selectedFields is warned and silently dropped rather than crashing, and an outright helper throw falls back identically. Also asserted the exact opts reaching the helper.
Migrates the anthropic branch of generateListName (site getmaxun#4 of 9, issue set_list_name tool. - Appends setListNameTool to server/src/sdk/anthropicTools.ts. - This is the only one of the 9 sites converting a free-text completion (not a JSON-shaped one) into a structured tool call - the prompt previously asked for bare text like "Product Listings", not JSON. - Unlike sites getmaxun#1-3, this branch does NOT early-return: the shared tail here is pure string post-processing (quote-strip, first-line-only, length validation, Title-Case) with no JSON.parse, so it works identically whether it receives raw text (ollama/openai) or decision.listName (anthropic). Assigning `llmResponse = decision.listName` and falling through to the unchanged shared tail is the smaller, more faithful port than duplicating that logic inline would have been. - max_tokens bumped 20 -> 80 for the anthropic branch only (ollama/openai untouched). The prior budget was sized for bare-text output with zero JSON overhead; a {"listName": "..."} tool call needs headroom on top of a name that can legally run up to 50 chars per the existing validation. Left uncorrected, this would risk stop_reason: max_tokens truncation on longer names, converting what worked before into a guaranteed "List 1" fallback for exactly the names most likely to need one. - temperature 0.1 preserved as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 7 scenarios: clean valid name, quote-wrapped name correctly stripped, multi-line response correctly truncated to its first line, an empty name correctly throws internally and falls back to "List 1" via the EXISTING (llmResponse || '').trim() guard - unchanged, no new guard code needed - an undefined listName field degrades through that same existing guard identically, an oversized (>50 char) name correctly throws and falls back, and a thrown helper error (e.g. simulated truncation) falls back identically. Also asserted opts.maxTokens === 80 specifically, to catch any regression of the budget bump.
…tion Migrates the anthropic branch of verifyWorkflowOutput (site getmaxun#5 of 9, issue with a forced verify_extraction_match tool. - Appends verifyExtractionMatchTool to server/src/sdk/anthropicTools.ts. required: ['matches'] only, matching the sibling Ollama jsonSchema exactly (this was corrected during blueprint review from an earlier draft that over-required confidence/reasoning too - reverted to match the only real precedent and the call site's own soft-default handling). - Typed as callAnthropicWithTool<any>, same rationale as sites getmaxun#2/getmaxun#3: the call site treats matches/confidence/reasoning as optional-with-defaults via typeof guards (`typeof decision.matches === 'boolean' ? ... : true`, etc.), not hard requirements. A narrower type would make those guards look redundant when they are not actually enforced at runtime. - Anthropic branch returns directly (this function's shared tail does JSON.parse, same as sites getmaxun#1/getmaxun#3, so early-return is correct here - unlike site getmaxun#4's fall-through, which was correct there because that tail is pure string processing with no JSON.parse). - Preserves the exact defensive extraction and its logger.info result line verbatim, just reading from `decision` instead of `parsed`. - Preserves max_tokens 256 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 6 scenarios, most importantly distinguishing the two different failure modes this function has: a decision that resolves successfully but is empty/malformed (`{}`) takes the SUCCESS path and produces reasoning: '' via the field-level typeof defaults, while a thrown error from the helper takes the CATCH path and produces the pre-declared fallback constant's distinct reasoning: 'Verification skipped (LLM unavailable)' - confirmed these remain genuinely different code paths producing different values, not collapsed into one. Also verified matches defaulting to true on wrong-type input, confidence defaulting to 0.5 on wrong-type input, and that each default is independent (a bad `matches` doesn't affect a valid `confidence` in the same response, and vice versa).
Migrates the anthropic branch of parseSearchIntent (site getmaxun#6 of 9, issue with a forced parse_search_intent tool. - Appends parseSearchIntentTool to server/src/sdk/anthropicTools.ts. required: ['searchQuery', 'extractionGoal'] only, matching the sibling Ollama jsonSchema exactly - limit stays optional since the call site treats an absent key and an explicit null identically. - Typed with a precise generic ({searchQuery: string; extractionGoal: string; limit: number | null}), not <any> - unlike sites getmaxun#2/getmaxun#3/getmaxun#5, this site's hard-throw check (`!intent.searchQuery || !intent.extractionGoal`) is a value/truthiness check, not a structural one. A `string` type annotation doesn't make a truthy-check on a possibly-empty string look redundant the way it would for e.g. an Array.isArray check, so the precise type doesn't undermine anything here (same reasoning as site getmaxun#1). - Anthropic branch returns directly; this function's shared tail does JSON.parse, so early-return is correct here (matching sites getmaxun#1/getmaxun#3/getmaxun#5). - The catch block's REGEX-BASED heuristic fallback (extracting a search query via /from\s+([^,\.]+)/i and a limit via /(\d+)/ straight from the raw prompt) is untouched - this is the only one of the 9 sites whose fallback isn't a static constant or identity mapping. - Preserves max_tokens 256 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 6 scenarios: valid full response, a null limit passed through correctly, an empty searchQuery correctly throwing internally and falling back to the regex heuristic (confirmed it extracts the right search term AND the right numeric limit from the raw prompt, and that the fallback's extractionGoal is the full raw prompt - not the mock's rejected value), an empty extractionGoal taking the same throw-and-fallback path, a prompt with no "from X" clause correctly degrading the heuristic's searchQuery to the first 50 characters, and an outright helper throw falling back identically.
Migrates the anthropic branch of selectBestUrlFromResults (site getmaxun#7 of 9, issue getmaxun#1178) off regex fence-stripping + JSON.parse onto callAnthropicWithTool with a forced select_best_url tool. - Appends selectBestUrlTool to server/src/sdk/anthropicTools.ts. required: ['selectedIndex', 'confidence', 'reasoning'] matches the sibling Ollama jsonSchema exactly - no precedent divergence here. - Typed as callAnthropicWithTool<any>, not a precise type - unlike site getmaxun#6's pure truthiness checks, this site's hard-throw explicitly compares `decision.selectedIndex === undefined`. An explicit undefined comparison is an existence/structural check (same category as site getmaxun#3's Array.isArray), not a plain truthy check, so a `number` type annotation here would risk making the check read as dead code to a future maintainer even though it is not actually enforced at runtime. - Anthropic branch returns directly; this function's shared tail does JSON.parse, so early-return is correct (matching sites getmaxun#1/getmaxun#3/getmaxun#5/getmaxun#6). - The length===1 short-circuit before the try block, and the catch block's searchResults[0]-based fallback (confidence 0.6, fixed reasoning string), are both untouched. - Preserves max_tokens 256 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 8 scenarios, most importantly: confirmed the length===1 short-circuit never invokes the helper at all (asserted zero calls), and confirmed selectedIndex: 0 - a value a careless truthy-check refactor could easily misread as "missing" - is correctly honored as a valid index rather than triggering the invalid-index fallback. Also covered undefined, negative, and out-of-bounds selectedIndex all correctly throwing internally and falling back to the first search result with the exact fixed confidence/reasoning, a valid index with confidence/reasoning omitted correctly using the `||` defaults (0.5 / 'No reasoning provided'), and an outright helper throw falling back identically.
…cation Migrates the anthropic branch of isMultiSitePrompt (site getmaxun#8 of 9, issue with a forced classify_multi_site_prompt tool. - Appends classifyMultiSitePromptTool to server/src/sdk/anthropicTools.ts. required: ['multiSite'] matches the sibling Ollama jsonSchema exactly. - This site has a distinctive 3-way control flow with NO hard throw: 1. Valid boolean multiSite -> logs `isMultiSitePrompt: <value>`, returns it directly. 2. Response received but multiSite missing/wrong type -> SILENTLY returns false (no log at all - the original only logs on this path via nothing, since there's no explicit branch for it, it just falls through). Reproduced this exact silence rather than adding a log line that wasn't there before. 3. Helper throws -> propagates to the function's EXISTING outer catch (unchanged), which logs the exact original warning message and falls through to the EXISTING final `return false` (unchanged). - Did NOT simplify this to `return decision.multiSite` - a malformed, non-boolean multiSite (e.g. the string "true") would then be returned as a truthy-but-wrong value instead of correctly degrading to false. Kept the `typeof decision.multiSite === 'boolean'` guard verbatim. - The anthropic branch now always returns from within its own block (either the boolean or the inline `return false`), so it never falls through to the shared regex/JSON.parse tail - verified this doesn't break TypeScript's definite-assignment analysis for the still-shared `llmResponse` variable used by ollama/openai. - max_tokens 20 and temperature 0 preserved unchanged (this call already asked for JSON-shaped text, like site getmaxun#8's sibling isMultiSitePrompt itself - no budget bump needed here, unlike site getmaxun#4's free-text case). Verified: full project tsc --noEmit clean. Mocked runtime check (ts-node) covered 5 scenarios, with logger.info/logger.warn also monkey-patched to assert directly on which log lines fire (not just the return value): multiSite: true logs and returns true; multiSite: false ALSO logs (info line fires for both booleans) and returns false; an empty decision object returns false with ZERO log calls, matching the original's silence for this specific case; multiSite as a non-boolean string ("true") is correctly rejected by the typeof guard and also returns false silently - confirming a truthy-coercion bug isn't hiding here; and a thrown helper error is caught by the pre-existing catch, logs the exact original warning text, and returns false via the pre-existing fallthrough.
Migrates the anthropic branch of selectMultipleUrlsFromResults (site getmaxun#9 of 9, issue getmaxun#1178) off regex fence-stripping + JSON.parse onto callAnthropicWithTool with a forced select_multiple_urls tool. This is the last of the 9 call sites - the migration is now complete. - Appends selectMultipleUrlsTool to server/src/sdk/anthropicTools.ts. required: ['selectedIndices'] matches the sibling Ollama jsonSchema exactly (reasoning stays optional, same precedent). - Typed as callAnthropicWithTool<any>, same rationale as sites getmaxun#3/getmaxun#7/getmaxun#8: `!Array.isArray(decision.selectedIndices)` is a structural/existence check that a precise array type would risk making look dead. - This site has the most fallback-triggering paths of the 9: a local `fallback()` closure (declared outside the try block, using `searchResults` and `cap` from the enclosing scope) is called INLINE in three places, not via throw - (1) the pre-try `cap <= 1` short-circuit, untouched, (2) when selectedIndices is missing/empty, (3) when the per-index filtering loop (type/range check + domain dedup via `new Set<string>()`) leaves fewer than 2 results. Only the fourth path - an actual thrown error - routes through the existing outer catch. Ported the filtering loop and both inline fallback() calls verbatim, reusing the original `seen`/`result` variable names in the nested block scope (matching every prior site's convention - an earlier draft of this commit accidentally renamed them to seenAnthropic/resultAnthropic to "avoid a collision" that block scoping already prevents; reverted before this landed, for consistency with sites getmaxun#2/getmaxun#3/getmaxun#5/getmaxun#6/getmaxun#7's identical reuse of decision/labelMapping/etc. in their own nested blocks). - Preserves max_tokens 256 and temperature 0.1 exactly as before. Verified: full project tsc --noEmit clean (including confirming the reused seen/result names don't collide with the shared tail's own same-named declarations, exactly as precedent predicted). Mocked runtime check (ts-node) covered 8 scenarios: the cap<=1 short-circuit correctly never invokes the helper at all (asserted zero calls); a valid 3-index selection returns entries in the right order with the mocked reasoning; a selection including a duplicate-domain index correctly dedupes (keeps the first occurrence, drops the later one); a non-array selectedIndices correctly triggers the inline fallback() (not a throw); an empty array does the same; an array of entirely out-of-range/wrong-type indices filters down to zero results and correctly falls back; a single valid-but-lone result also falls back (the >= 2 threshold); and an outright helper throw is caught by the pre-existing catch and falls back identically. This completes the tool_choice migration for all 9 Anthropic call sites in workflowEnricher.ts. `new Anthropic(` now has zero remaining call sites in this file - the top-level `import Anthropic from '@anthropic-ai/sdk'` is consequently dead code. Deliberately NOT removed in this commit to keep it scoped to site getmaxun#9 only, matching every prior commit's scope discipline; flagging as an explicit, obvious follow-up rather than silently leaving it dangling or silently sneaking an unrelated cleanup into this diff.
All 9 anthropic branches now go through callAnthropicWithTool; the raw `new Anthropic(...)` client construction that used to happen per-call-site is gone as of the site getmaxun#9 migration (372ded1). The top-level `import Anthropic from '@anthropic-ai/sdk'` had zero remaining references - confirmed via `grep -n '\bAnthropic\b'` before removing it.
All 3 verified against current code and the actual failure modes before fixing, not applied blindly from the bot's suggestion text. 1. getLLMDecisionWithVision: the Anthropic image block declared media_type: 'image/png' while the screenshot is captured as JPEG (page.screenshot({ type: 'jpeg' })). This is the exact mismatch already disclosed (by me) in the PR's "Note to Reviewers" before CodeRabbit caught it independently, confirmed against Anthropic's own docs that a media_type mismatch can 400 before the forced tool call ever runs. Fixed to 'image/jpeg'. The identical bug also exists in the untouched openai branch's `data:image/png;base64,...` URL - left as-is and flagged, not silently fixed, since that branch is explicitly out of this PR's scope. 2. parseSearchIntent: the validation `!intent.searchQuery || !intent.extractionGoal` is a truthiness check, not a type check. Since callAnthropicWithTool returns raw tool_use.input with no strict-mode validation, a non-string value (e.g. an object) passes this guard, and downstream `encodeURIComponent(query)` (workflowEnricher.ts, both performDuckDuckGoSearch and performDuckDuckGoMultiSearch) silently turns it into the literal string "[object Object]" as a search query. Verified this exact call chain before fixing. Replaced with a guard that requires searchQuery/extractionGoal to be non-blank strings and limit (when present) to be an integer. Applied to both the anthropic branch's copy of this check AND the shared ollama/openai JSON-parsing branch's identical copy, per CodeRabbit's own comment text ("Apply the same validation to the JSON parsing branch") - not my own scope expansion, the finding explicitly asked for both. 3. selectMultipleUrlsFromResults: the per-index collection loop had no cap on `result.length`, so a tool response returning more valid, unique-domain indices than the caller's `maxSites`/`cap` would collect all of them instead of stopping at cap - e.g. 5 valid indices with cap=4 would produce 5 downstream workflows instead of 4. Added `if (result.length >= cap) break;` at the top of the loop, matching CodeRabbit's exact suggested diff. This identical bug also exists, unchanged, in the original shared-tail copy of this same loop (which predates this PR and serves ollama/openai) - CodeRabbit's finding did not ask for that copy to be fixed too, so it's flagged, not touched. Verified: full project tsc --noEmit clean. A targeted test reproduced each finding's exact described failure mode against the pre-fix code path conceptually and confirmed the fix resolves it: searchQuery as an object, as an array, as an empty/whitespace string, limit as a fraction, and limit as a numeric string are all now correctly rejected (falling back to the existing regex heuristic, not silently proceeding); valid inputs including an omitted limit still succeed unchanged; 5 valid unique-domain indices against cap=4 now correctly returns exactly 4, and a below-cap selection is unaffected. Re-ran the full 9-site fallback regression afterward to confirm the shared-code changes (finding getmaxun#2) didn't affect any of the other 8 sites.
…un#1189 Reject __proto__/constructor/prototype field names and use a null-prototype target in filterFieldsByIntent's Anthropic branch to prevent prototype pollution from untrusted tool output. Add explicit type validation for first/second/reason/limit in getLLMDecisionWithVision's Anthropic branch, since input_schema isn't runtime-enforced without strict mode. Reject non-positive and non-safe-integer limit values in both parseSearchIntent validation blocks (Anthropic branch and shared ollama/openai tail).
Requested by maintainer review on PR getmaxun#1189. The forced tool_choice call in isMultiSitePrompt's Anthropic branch left too little headroom at 20 tokens, risking truncation before the tool_use block completes.

- Around line 1036-1057: Validate labelMapping keys and values before returning
from the decision-label branch, matching the prototype-sensitive name checks
used by the sibling branch: accept only valid string labels and reject names
such as "__proto__" that could alter object behavior. Ensure invalid mappings
are handled safely while preserving the existing missing-label fallback.
- Around line 458-462: Update the limit validation in the decision handling flow
around buildWorkflowFromLLMDecision to accept only positive safe integers,
rejecting zero, negative, fractional, and unsafe numeric values while retaining
null as valid. Align this check with the existing parseSearchIntent validation
before the fallback assignment to limit.

…un#1189 Reject non-positive/fractional limit values in getLLMDecisionWithVision's Anthropic branch, matching the positive-safe-integer rule already enforced in parseSearchIntent. Validate and sanitize generateFieldLabelsBatch's Anthropic-branch label mapping before returning it: reject non-string, blank, and __proto__/constructor/prototype values, since callers use each value as an object key downstream (renamedFields[semanticLabel] = ...).

Summary
Replaces regex fence-stripping +
JSON.parsewith forced Anthropictool_choiceat all 9 Anthropic call sites inserver/src/sdk/workflowEnricher.ts. Each site previously asked Claude to reply with free-form text (sometimes JSON-shaped, sometimes not) and recovered structure via markdown-fence regex andJSON.parse. That path is replaced with one named tool per decision, forced viatool_choice: {type: 'tool', name, disable_parallel_tool_use: true}, whosetool_use.inputarrives pre-parsed, no string extraction, no regex, noJSON.parseon the Anthropic path.ollamaandopenaibranches are untouched, per the issue's own scope limit.What changed

All 9 sites still default to
llmConfig?.model || 'claude-3-5-sonnet-20241022', unchanged, per the issue's own explicit instruction ("Leave the model string exactly as it is. No model migration here."). Flagging beyond what the issue asked:claude-3-5-sonnet-20241022is a retired model ID (retired 2025-10-28), so these calls will fail outright in production unless the caller passes a currentmodelviallmConfig. This predates this PR and isn't introduced or fixed by it. Fixing it isn't a one-line change, 8 of the 9 sites also send an explicittemperature, and current-generation Claude models reject any request that includestemperature/top_p/top_kat all, so a model bump and the temperature removal have to land together. Filing as a follow-up rather than bundling it here.Also pre-existing and out of scope:
getLLMDecisionWithVisiondeclares its screenshot'smedia_typeasimage/pngwhile it's actually captured as JPEG (page.screenshot({ type: 'jpeg' })). Untouched by this PR; noting it since it was visible while migrating that call site.One scope question worth a maintainer's explicit sign-off: the issue says this ticket touches
workflowEnricher.tsonly. This PR also adds two new sibling files (anthropicToolHelper.ts,anthropicTools.ts) in the same directory, whose only purpose is serving these 9 call sites, no other file was touched or created. I read the issue's scope limit as being about not touching other files' unrelated call paths (the three named exclusions above), not a literal ban on new same-purpose support files, but happy to inline everything back intoworkflowEnricher.tsif a stricter reading is preferred.Summary by CodeRabbit
