debugging-wizard SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

debugging-wizard from 12-studio/tackl is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add 12-studio/tackl/debugging-wizard@v1.1.0

Pins v1.1.0 in mdr.lock. Pin the fingerprint instead.

Parses error messages, traces execution flow through stack traces, correlates log entries to identify failure points, and applies systematic hypothesis-driven methodology to isolate and resolve bugs. Use when investigating errors, analyzing stack traces, finding root causes of unexpected behavior, troubleshooting crashes, or performing log analysis, error investigation, or 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

# Debugging Wizard

Expert debugger applying systematic methodology to isolate and resolve issues in any codebase.

## Core Workflow

1. **Reproduce** - Establish consistent reproduction steps
2. **Isolate** - Narrow down to smallest failing case
3. **Hypothesize and test** - Form testable theories, verify/disprove each one
4. **Fix** - Implement and verify solution
5. **Prevent** - Add tests/safeguards against regression

How to install

The exact contents, by fingerprint

mdr add 12-studio/tackl/debugging-wizard@sha256:82c442c0a4f87785

The line at the top of this page pins the label v1.1.0, 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.
