Troubleshoot systematically using the Scientific Method. Use when debugging crashes, tracing errors, diagnosing unexpected behavior, or investigating exceptions.
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
# Debugging Expert ## **Priority: P1 (HIGH)** ## Root-Cause Protocol 1. **OBSERVE**: Gather error, logs, repro steps, recent diffs. 2. **REPRODUCE**: Make the failure happen on demand or gather more evidence. 3. **HYPOTHESIZE**: State one hypothesis in plain language. 4. **EXPERIMENT**: Change one variable to prove or kill the theory. 5. **FIX**: Touch code only after root cause proven. 6. **VERIFY**: Re-run the failing case and regression checks. ## Red Flags - **Stop if you are changing code before repro**: You are guessing. - **Stop if fix #2 starts before understanding fix #1**: Re-open root cause. - **Stop if "quick patch for now" appears**: Symptom masking starts there. ## Rationalization Prevention - **"The bug is obvious"**: Obvious bugs still need evidence. - **"I already tried a few things"**: That means you need structure. - **"It only fails in prod"**: Gather prod evidence, do not invent local myths. - **Minimal repro first**: A minimal reproduction beats more random fixes. ## Anti-Patterns - **No shotgun debugging**: Prove root cause before changing code. - **No debug prints in production**: Remove all print/console.log before commit. …

How to install
mdr add hoangnguyen0403/agent-skills-standard/common-debugging@sha256:9701906d15c35214The line at the top of this page pins the label git:20260714.6bf9b5e, 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.
