deep-debugging SKILL.md skillA

deep-debugging from nguyenthienthanh/aura-frog is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add nguyenthienthanh/aura-frog/deep-debugging@git:20260515.6be9f59

Pins git:20260515.6be9f59 in mdr.lock. Pin the fingerprint instead.

Systematic debugging protocol for bugs that resist quick fixes. Use bisection, hypothesis trees, and scientific method when a bug isn't obvious from the stack trace. Goes beyond bugfix-quick for production-grade root cause analysis.

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

> **AI-consumed reference.** Optimized for Claude to read during execution.
> Human-readable explanation: see [docs/architecture/HIERARCHICAL_PLANNING.md](../../../docs/architecture/HIERARCHICAL_PLANNING.md)
> or [docs/getting-started/](../../../docs/getting-started/) depending on topic.

# Deep Debugging

For bugs where `bugfix-quick` fails. Apply scientific method, not vibes.

**Escalation path:** `bugfix-quick` (< 15 min, clear cause) → `deep-debugging` (scientific method)
**Uses:** `tree-of-thoughts` skill for hypothesis trees, `chain-of-verification` for claim validation

## When to Use vs. bugfix-quick

| Signal | Use |
|--------|-----|
| Stack trace points to clear line | bugfix-quick |
| Reproduces 100% of the time | bugfix-quick |
| Happens in known edge case | bugfix-quick |
| Intermittent / flaky | **deep-debugging** |
| Multiple plausible causes | **deep-debugging** |
| "Works on my machine" class | **deep-debugging** |
| Timing / race conditions | **deep-debugging** |
| Production-only, can't repro locally | **deep-debugging** |

## The Protocol

### Step 1 — Reproduce reliably

Cannot debug what you can't reproduce. Goals:
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add nguyenthienthanh/aura-frog/deep-debugging@sha256:54e578d3a1506dd8

The line at the top of this page pins the label git:20260515.6be9f59, 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.
