type:debug

Hypothesis-driven debugging skill. Use when a bug, test failure, crash, or unexpected behavior is reported. Auto-trigger on error pastes or "broken/doesn't work/failing" language. Explicit invocation: /atomic-debug. Output: symptom statement → hypothesis table → cheapest test first → root cause. No symptom-patching. Boundary with atomic-tdd: this skill owns diagnosing an unknown root cause. Once the cause is known and you are writing the fix, that is atomic-tdd's job (failing test first, then the fix).
