Debugging Wizard

What it does

When your agent uses it

• Investigating errors
• Analyzing stack traces
• Finding root causes of unexpected behavior
• Troubleshooting crashes

Example prompts

• “Use the debugging-wizard skill to parse error messages, traces execution flow through stack traces, correlates log entries to identify failure…”
• “/debugging-wizard”

Requirements

• Python 3
• Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 3cdd0ee. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • git
  • python
  • node

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Debugging Wizard loads about 909 tokens when it runs, and up to ~7.5k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~103

When it runs · the whole SKILL.md, loaded when a task matches

~909

With references · SKILL.md plus every file in references/, read only if the agent opens them

~7.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

debugging-wizard

description

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.
