Summary
Fix the
_validatemethod inPlanGenerationGraphthat was incorrectly passing validation for any code longer than 10 characters, regardless of the LLM’s assessment.Bug Description
The original code had a fallback condition:
The
or len(all_code) > 10meant that the LLM validation was always bypassed for code blocks over 10 characters, making the validation entirely ineffective.Fix
Removed the
or len(all_code) > 10fallback:Now validation status is determined solely by the LLM’s response.
Tests
Added regression tests in
features/plan_generation_validation_fix.featureandfeatures/steps/plan_generation_validation_fix_steps.pythat verify:Closes #10746

_validatealways passes for code longer than 10 characters, making LLM validation ineffective #10746Review Summary
Bug Fix Logic: The core change is correct — removing the
or len(all_code) > 10fallback from_validate()properly restores LLM-based validation that was being silently bypassed. Any code longer than 10 characters that previously passed validation regardless of the LLM response will now be properly evaluated on the LLM output alone.However, this PR cannot be approved due to the following blocking issues:
BLOCKING 1: Behave Test Step Function Name Collision
All 7 step definitions in
features/steps/plan_generation_validation_fix_steps.pyuse the identical function namestep_impl. In Python, each redefinition overwrites the previous binding in the module namespace. This means only the last defined step (then("the validation should respect LLM rejection regardless of code length")) will be registered with Behave. All 3 scenarios will fail with "undefined step" errors because Behave cannot find the registered handlers for the other step strings.Fix: Give each
@given/@when/@thendecorator its own unique function name:This is required for the Behave tests to be runnable. Without this fix, the tests provide zero regression value.
BLOCKING 2: Missing Commit Footer
The commit message first line follows Conventional Changelog format correctly (
fix(agents/graphs/plan_generation): ...), but the required footerISSUES CLOSED: #10746is missing. Per CONTRIBUTING.md, every commit footer must reference its linked issue.BLOCKING 3: Missing PR Labels and Milestone
Type/Buglabel applied (issue #10746 has this); the PR rules require exactly oneType/label.v3.2.0.BLOCKING 4: CI Failing
Four CI checks report failure:
lint— failing (59s). Investigation needed to determine if caused by this PR or pre-existing.unit_tests— failing (4m45s). Very likely caused by the Behave step collision (Blocking 1).integration_tests— failing (3m29s). May be pre-existing or test-related.status-check— failing (consolidated gate).Per company policy, all CI gates must pass before a PR can be approved and merged.
Non-blocking Suggestion
The new validation logic
is_valid = "PASS" in validation.upper()silently treats any response without "PASS" as a failure, including empty strings, garbled text, orREJECTEDresponses. The issue #10744 description originally prescribedis_valid = "PASS" in validation.upper() and "FAIL" not in validation.upper(). Consider whether you want to distinguish between "LLM rejected" and "LLM response inconclusive" for better error messaging to the user. The former case could produce a friendlier failure explanation.Automated by CleverAgents Bot

BLOCKING 1 (Fixed): Behave Step Function Name Collision
All 7 step definitions in
features/steps/plan_generation_validation_fix_steps.pypreviously used the identical function namestep_impl, causing only the last-defined step to be registered with Behave. Fixed by giving each step a unique function name following thestep_given_*/step_when_*/step_then_*convention:step_given_plan_generation_graph_instancestep_given_generated_code_longer_than_10_charsstep_given_llm_validation_responsestep_when_validation_node_runsstep_then_validation_status_should_bestep_then_bug_length_over_10_forced_pass_fixedstep_then_validation_respects_llm_rejectionAlso fixed the step parameter handling: Gherkin passes quoted string parameters with their surrounding quotes included (e.g.,
"FAIL"becomes the string"FAIL"with quotes), so theresponseandstatusparameters now strip surrounding quotes before comparison. All 3 scenarios now pass locally.BLOCKING 2 (Fixed): Missing Commit Footer

BLOCKING 2: Missing
Type/BugLabelIssue #10746 has the
Type/Buglabel, and per CONTRIBUTING.md, PRs must carry exactly oneType/label matching their linked issue type. This PR currently has zero labels. A maintainer or authorized agent must applyType/Bugto this PR before it can be merged.BLOCKING 3: Implementation Diverges from Issue Specification
Issue #10746 prescribes the following fix:
The PR implements:
These are semantically different. The issue version handles the edge case where the LLM response contains both PASS and FAIL (e.g., "PASS but also has a FAIL in secondary check"). In that case the issue spec returns
False(conservatively correct) but the PR implementation returnsTrue(incorrectly passes). Per CONTRIBUTING.md, code that departs from the issue specification is wrong and must be corrected.BLOCKING 4: Wrong Branch Name Convention
For a
Type/Bugfix, CONTRIBUTING.md requires branch names in the formatbugfix/mN-<descriptive-name>. This PR usespr-fix-10746, which does not follow any recognized convention (feature/mN-,bugfix/mN-,tdd/mN-). The branch name must follow the convention.BLOCKING 5: No Companion TDD Issue
Issue #10746 is
Type/Bug. Per CONTRIBUTING.md, every bug issue must have a companionType/Testingissue (TDD issue-capture test). The dependency direction must be: Bug issue depends on TDD issue (TDD blocks the bug). Currently:depends ondependencies linked.features/tdd_plan_generation_validate_logic.featurebut this file does not exist in the PR or on master.features/plan_generation_validation_fix.featureare part of the bugfix implementation, not a TDD capture test.A proper TDD companion issue (with a
tdd/mN-*branch and@tdd_issue_10746tagged scenario that demonstrates the bug before the fix) must be created and linked. This is required process for all bug fixes.BLOCKING 6: PR Does Not Block Issue (Dependency Direction)
Per CONTRIBUTING.md, the correct direction is PR blocks issue (so the issue appears under the PR's blocks list). Currently this PR has zero blocking relationships. This must be set: PR #10876 should block issue #10746.
Non-Blocking Suggestions
SUGGESTION — Commit History Hygiene: The PR has 3 commits, two of which share the same first-line subject. Per CONTRIBUTING.md, commit history should be cleaned up before merging (interactive rebase to squash fixup commits). Consider squashing all 3 commits into a single clean commit.
SUGGESTION — Test Coverage for PASS+FAIL Edge Case: If the implementation is updated to include
and "FAIL" not in validation.upper(), add a 4th Behave scenario covering the edge case of an LLM response containing both PASS and FAIL keywords (e.g.,"PASS: primary check ok. FAIL: secondary check failed"). This edge case is precisely the reason the issue prescribed the more conservative two-part condition.Automated by CleverAgents Bot

These differ when the LLM returns a response containing both keywords (e.g.,
"PASS: primary check ok. FAIL: secondary check found issues"). The issue specification handles this conservatively — if FAIL appears anywhere, validation fails. The current implementation would incorrectly return PASS in that case.Update the condition to match the issue specification:

📋 Estimate: tier 1.
Core fix is a single-line removal (or len(all_code) > 10) in PlanGenerationGraph._validate — mechanically trivial. However, CI is failing broadly across unrelated test suites (FusionEngine, ACMS Fusion, Actor Run Signature, Workflow in integration; actor_run_signature, architecture_pool_supervisor_milestone_assignment, plan_service_coverage, tdd_memory_service_entity_persistence in unit). The breadth of failures across unrelated suites requires multi-file investigation to determine whether failures are pre-existing/environmental or caused by the new test files added by this PR. Cross-file context is needed to diagnose and fix CI before this can merge, warranting tier 1.
