Use when the user reports a bug, broken behavior, regression, failing test, or asks to investigate/root-cause/debug. Trigger on: 修个 bug, 这个 bug, 排查一下, 复现, 这个错怎么回事, 为什么 X 不工作, debug, RCA, fix this bug, investigate, reproduce. Guides root-cause debugging: reproduce with a failing test, list hypotheses, trace backward, fix only the confirmed cause, verify red-green-red, and leave a regression test. Does not symptom-patch or write commit messages.
Passed 14 of 18 test cases with the skill, and 2 of 18 without it.

Tokens, turns and time describe resource use, not a dollar price.
One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
When generating the fix summary markdown file for a resolved bug, specify the prefix required for items in the verification section.
| Checked | Without skill | With skill |
|---|---|---|
| Uses the V- prefix for verification criteria items instead of AC-. | Missed | Passed |
The instructions your model reads when the skill loads.
Hypothesis-driven debugging & fix workflow with No fix without root cause. Replaces guess-and-patch with: reproduce → hypothesize → diagnose (backward trace) → fix → defense-in-depth → verify → regress.
This skill only debugs and fixes. It does not gather feature requirements (that's dev-grill-docs; dev-spec is a compatibility alias), does not plan large refactors (that's dev-plan), and does not write commit messages on its own (that's dev-code-review / dev-commit-writer after the fix is in).
Use this skill when the user reports a bug, asks why something is broken, or wants a structured root-cause-driven fix.
