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

# Diagnosing Bugs

Systematically diagnose bugs using the scientific method: hypothesis, experiment, conclusion.

## Process

1. **Reproduce** — Can you make the bug happen reliably?
2. **Observe** — What exactly happens vs. what's expected?
3. **Hypothesize** — What could cause this behavior?
4. **Experiment** — Test one hypothesis at a time.
5. **Conclude** — What did the experiment prove or disprove?
6. **Fix** — Now that you know the cause, fix it.
7. **Verify** — Confirm the fix works and doesn't break other things.

## Rules

- One hypothesis at a time.
- Don't skip reproduction.
- Don't guess — test.
- Document what you learned.

## Credit

How to install

The exact contents, by fingerprint
mdr add ctaxnagomi/agent-kd-skill/diagnosing-bugs@sha256:a127175df2ce7df8

The line at the top of this page pins the label git:20260826.54f6831, 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.
