Name: common-debugging
Author: hoangnguyen0403

This file is byte-identical to the first copy the registry indexed, one of 3 copies on public GitHub. Same content hash, same audit grade.

common-debugging is agent-read markdown (skill) from hoangnguyen0403/agent-skills-standard: Troubleshoot systematically using the Scientific Method. Use when debugging crashes, tracing errors, diagnosing unexpected behavior, or investigating exceptions..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.
