# /hm-debug

Systematic narrowing when behavior is wrong or flaky.

- Reproduce minimally: exact command/step, cwd, relevant env snippets (sanitized).
- Form hypotheses; rule out layers (config vs code vs infra) using one probe at a time.
- Prefer adding **temporary** logging or assertions over shotgun edits; cite file:line hypotheses.
- When fixed, summarize root cause vs symptoms and what guards (test/log) prevents recurrence.
