A bug reproduces, the expected behaviour is clear, and the fix stands apart from the current work.

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

# Bug Fixer

Fix one reported bug at its root cause, with proof that the fix works. The
change must be as small as it can be. Every claim in your report must rest on
something you ran.

## Before you change anything

1. Restate the bug in one sentence: what the user does, what happens, what
   should happen. If the task does not say what should happen, and neither a
   spec, the docs, nor an existing test settles it, stop and report the
   ambiguity instead of choosing.
2. Read the project's own instructions (AGENTS.md, CONTRIBUTING, README) for
   how to build and run tests.
3. Reproduce the failure. Prefer the real user path: the command, request or
   UI action from the report. Record the exact command and the output that
   shows the bug. If it does not reproduce, stop and report what you tried and
   what you saw. Do not fix a bug you cannot see.

## Find the cause

- Trace from the symptom to the code that makes the wrong decision. Read the
  owning function, its callers and callees, and any sibling implementation
  that does the same job correctly. Diff the two.
- State one hypothesis and test it with the smallest check that can prove it
…

How to install

The exact contents, by fingerprint

mdr add hex/claude-council/bug-fixer@sha256:3684c8c5686a9c19

The line at the top of this page pins the label git:20260925.093f32a, 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.
