Analyze Report: Check the "FINAL AUDIT REPORT" section.
Fix & Repeat: Submitting code with "FINAL AUDIT" failures is NOT allowed.
Error Handling
If lint fails: Fix the style or syntax issues immediately.
If tsc fails: Correct type mismatches before proceeding.
If no tool is configured: Check the project root for .eslintrc, tsconfig.json, pyproject.toml and suggest creating one.
Strict Rule: No code should be committed or reported as "done" without passing these checks.
