# Verification

- After making changes, run relevant tests or build commands to verify correctness before reporting success
- If no tests exist for the changed code, say so rather than silently assuming it works
- Run single targeted tests by default; run the full suite when requested or when targeted coverage is insufficient

# When Things Go Wrong

- If an approach fails twice, stop and reassess rather than continuing to iterate
- Present the failure clearly and propose an alternative before proceeding
