Summary

This PR fixes a critical bug in the PlanGenerationGraph._validate() method where the validation logic was using an OR operator instead of AND, causing validation to always pass for code longer than 10 characters, effectively bypassing LLM validation.

Changes

  • Fixed validation logic in src/cleveragents/agents/graphs/plan_generation.py:

    • Changed from: is_valid = "PASS" in validation.upper() or len(all_code) > 10
    • Changed to: is_valid = "PASS" in validation.upper() and "FAIL" not in validation.upper()
    • This ensures validation only passes when the LLM explicitly returns "PASS" and does not contain "FAIL"

  • Added comprehensive TDD tests for the validation logic (issue #10477):

    • New feature file: features/tdd_plan_generation_validate_logic.feature
    • New steps file: features/steps/tdd_plan_generation_validate_logic_steps.py
    • Tests cover various validation scenarios and edge cases
    • Properly tagged with @tdd_issue and @tdd_issue_10477

Why This Fix Was Needed

The original logic had a critical flaw: the OR operator meant that any code longer than 10 characters would be marked as valid, regardless of the LLM's actual validation response. This completely bypassed the intended LLM validation mechanism, allowing invalid plans to be accepted. The fix ensures that:

  1. Validation depends on the actual LLM response ("PASS" keyword)
  2. Explicit "FAIL" responses are properly rejected
  3. Code length is no longer a factor in determining validity

Testing

  • TDD tests added covering:
    • Valid plans with "PASS" in LLM response
    • Invalid plans with "FAIL" in LLM response
    • Edge cases and various response formats

All quality gates passing: lint ✓, typecheck ✓, unit_tests ✓

Closes #10480

Fix PlanGenerationGraph._validate logic by removing the erroneous
or len(all_code) > 10 condition that caused validation to always pass
for any generated code longer than 10 characters, completely bypassing
the LLM validation response.

The fix changes the is_valid calculation from:
  is_valid = 'PASS' in validation.upper() or len(all_code) > 10
to:
  is_valid = 'PASS' in validation.upper() and 'FAIL' not in validation.upper()

This ensures the LLM's judgment is respected regardless of code length,
restoring the retry logic and preventing invalid/broken code from passing
validation.

Also adds TDD tests (feature file and steps) for issue #10477 as the
TDD counterpart, with @tdd_issue and @tdd_issue_10477 tags.

Closes #10480

Applied a Ruff format fix in features/steps/tdd_plan_generation_validate_logic_steps.py by merging two f-string lines into one.

Updated two integration tests in robot/plan_generation_graph.robot to use FakeListLLM(responses=['PASS: code looks good']*10) instead of FakeListLLM(responses=['test']*3). This is necessary because the validation logic fix makes 'test' responses fail validation (they don't contain 'PASS'), causing the workflow to retry indefinitely. The tests now provide passing responses to reflect the new behavior.

[AUTO-IMP-PR-10731] Worker Attempt

  • Tier: 1 (haiku)
  • Attempted: Fixed two CI failures: (1) Format check failure - applied ruff format fix to features/steps/tdd_plan_generation_validate_logic_steps.py; (2) Integration test failures - updated robot/plan_generation_graph.robot Workflow Invoke and Stream tests to use FakeListLLM(responses=['PASS: code looks good']*10) instead of ['test']*3. The validation logic fix means 'test' responses no longer pass validation.
  • Result: success - lint, format, typecheck, unit_tests, and plan_generation_graph.robot integration tests all pass locally.
