debug SKILL.md skillA

debug from sd0xdev/sd0x-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add sd0xdev/sd0x-harness/debug@git:20260925.3600370

Pins git:20260925.3600370 in mdr.lock. Pin the fingerprint instead.

Interactive debugging workflow with hypothesis-driven probe loop. Use when: unknown bugs, script errors, silent failures, troubleshooting. Not for: known bugs (use bug-fix), GitHub issue analysis (use issue-analyze), code understanding (use code-explore). Output: debug report with probe journal + root cause + fix.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Debug Skill

## Trigger

- Keywords: debug, 除錯, troubleshoot, diagnose, 查問題, 找 bug, 為什麼不動, 為什麼不 work, something wrong, not working

## When NOT to Use

| Scenario | Alternative |
|----------|------------|
| GitHub Issue / PR thread 分析 | `/issue-analyze` |
| 已知根因、直接修復 | `/bug-fix` |
| 理解程式碼如何運作 | `/code-explore` |
| 需要雙視角確認邏輯 | `/code-investigate` |
| 部署後唯讀功能驗證 | `/feature-verify` |

## Prohibited Actions

```
❌ git add | git commit | git push — per @rules/git-workflow.md
```

This skill debugs and may fix code but does **not** commit. `/precommit` is a quality gate only. To commit, offer the menu per `rules/git-workflow.md` § Proactive Offer — a commit option on any real branch, a push option only where `review-state.js offer` allows one — and invoke `/smart-commit --execute` on selection; never print the command for the user to copy.

## Workflow

```
Phase 0    Phase 1     Phase 2          Phase 3           Phase 4        Phase 5
Intake  →  Classify →  Probe Loop   →   Root Cause    →   Fix +       →  Report
+ Repro    (Taxonomy)  (max 6)          Confirmation      Verify
  │          │           │                 │                │              │

How to install

The exact contents, by fingerprint
mdr add sd0xdev/sd0x-harness/debug@sha256:cb562a3c47b2c448

The line at the top of this page pins the label git:20260925.3600370, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
