# Section 03 Code Review Interview

## Triage Summary

| # | Severity | Issue | Action |
|---|----------|-------|--------|
| 1 | MEDIUM | sys.argv mutation without monkeypatch | Auto-fix applied |
| 2 | MEDIUM | Missing test_cli_import_does_not_register_tools | Let go — covered by server import check |
| 3 | LOW | Silent fall-through for unhandled subcommands | Auto-fix applied |
| 4 | LOW | /tmp/fake hardcoded path | Let go — test works correctly |
| 5 | LOW | Missing returncode check | Let go — stdout assertion sufficient |
| 6 | INFO | Skeleton has validation logic | Noted for section-04 |

## Auto-fixes Applied

1. **sys.argv test hygiene**: Changed `test_version_flag` and `test_help_flag` to use `monkeypatch.setattr("sys.argv", ...)` instead of direct mutation.
2. **Defensive else clause**: Added `else: parser.print_help(); sys.exit(1)` to cli.py dispatch for future-proofing.
