debug SKILL.md skillA

debug from me2resh/apexyard is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add me2resh/apexyard/debug@git:20261015.37f5689

Pins git:20261015.37f5689 in mdr.lock. Pin the fingerprint instead.

Hypothesis-driven debugging — architecture-first reading + evidence-before-fix. For bugs that resisted naïve fix attempts.

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

Writing: read docs/skills/shared/writing-rule.md before you write a durable artifact.

# /debug — Structured Debug Methodology

Most "stuck" debug sessions look the same: pattern-match on the symptom, propose a fix, ship it, find a different symptom, repeat. Each cycle costs a deploy + a CEO approval + the user's patience. This skill enforces the discipline that prevents the loop:

1. **Capture the symptom precisely** — the exact URL, the exact response, the exact step that fails.
2. **Read the architecture before guessing** — map every layer the request touches.
3. **Form a hypothesis ladder** — 3–5 candidate causes ordered by probability, each with an explicit evidence test.
4. **Gather evidence first, fix second** — never ship a fix without a verification step that would have caught the wrong hypothesis.
5. **Verify the fix against the original evidence** — re-run the symptom check, not just the unit tests.

The cost of one extra `curl`, one extra `Read`, one extra "what does the server actually return?" — is one minute. The cost of one wrong fix that ships, deploys, blocks the user, and then has to be diagnosed again is hours.

How to install

The exact contents, by fingerprint
mdr add me2resh/apexyard/debug@sha256:5fb7211982ba22f3

The line at the top of this page pins the label git:20261015.37f5689, 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.
