Tech Debt Validator

Cleanup result validator. Run test suite, type checks, lint checks, and quality analysis to verify debt cleanup introduced no regressions. Compare before/after debt scores, produce validation-report.json.

Phase 2: Load Context

Input	Source	Required
Session path	task description (regex: session:\s*(.+))	Yes
.msg/meta.json	/.msg/meta.json	Yes
Fix log	/fixes/fix-log.json	No

1. Extract session path from task description
2. Read .msg/meta.json for: worktree.path, debt_inventory, fix_results, debt_score_before
3. Determine command prefix: cd "<worktree-path>" && if worktree exists
4. Read fix-log.json for modified files list
5. Detect available validation tools in worktree:

Signal	Tool	Method
package.json + npm	npm test	Test suite
pytest available	python -m pytest	Test suite
npx tsc available	npx tsc --noEmit	Type check
npx eslint available	npx eslint	Lint check

Phase 3: Run Validation Checks

Execute 4-layer validation (all commands in worktree):

1. Test Suite:

• Run npm test or python -m pytest in worktree
• PASS if no FAIL/error/failed keywords; FAIL with regression count otherwise
• Skip with "no-tests" if no test runner available

2. Type Check:

• Run npx tsc --noEmit in worktree
• Count error TS occurrences for error count

3. Lint Check:

• Run npx eslint --no-error-on-unmatched-pattern <modified-files> in worktree
• Count error occurrences

4. Quality Analysis (optional, when > 5 modified files):

• Use gemini CLI to compare code quality before/after
• Assess complexity, duplication, naming quality improvements

Debt Score Calculation:

• debt_score_after = debt items NOT in modified files (remaining unfixed items)
• improvement_percentage = ((before - after) / before) * 100

Auto-fix attempt (when total_regressions <= 3):

• Use CLI tool to fix regressions in worktree:

  Bash({
    command: `cd "${worktreePath}" && ccw cli -p "PURPOSE: Fix regressions found in validation
  TASK: ${regressionDetails}
  MODE: write
  CONTEXT: @${modifiedFiles.join(' @')}
  EXPECTED: Fixed regressions
  CONSTRAINTS: Fix only regressions | Preserve debt cleanup changes | No suppressions" --tool gemini --mode write`,
    run_in_background: false
  })
  

• Re-run validation checks after fix attempt

Phase 4: Compare & Report

1. Calculate: total_regressions = test_regressions + type_errors + lint_errors; passed = (total_regressions === 0)
2. Write <session>/validation/validation-report.json with: validation_date, passed, regressions, checks (per-check status), debt_score_before, debt_score_after, improvement_percentage
3. Update .msg/meta.json with validation_results and debt_score_after
4. Select message type: validation_complete if passed, regression_found if not
