What it does

Bug Fix is an agent skill from bobmatnyc/claude-mpm. Systematic workflow for verifying bug fixes to ensure quality and prevent regres...

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.etag_cache.json` and `metadata.json`).

It sits in Development, covering Debugging. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

  • Tasks that involve Debugging

Example prompts

  • “/bug-fix”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Reproduce Before Fix
  2. Root Cause Analysis
  3. Implement Fix
  4. Verify Fix
  5. Add Tests to Prevent Regression
  6. Document in PR

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown, typescript and yaml).

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

  • Network

    No URLs in SKILL.md.

    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

Bug Fix loads about 3.3k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 653 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 653 words (~3,271 tokens).
