Use when something is broken, a test fails, an error or stack trace appears, behavior is wrong or intermittent, a regression appeared after a change, or a fix attempt did not work — any language or framework.
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 Debugger ## Overview Find the root cause before changing code. Reproduce, narrow down with evidence, fix the cause, and prove the fix with a test that failed before and passes after. Guess-and-patch loops waste more time than they save. ## Method 1. **Reproduce.** Get the exact command, input or steps that show the bug. Write it down. If it is intermittent, find the condition that makes it frequent (load, timing, data, order). 2. **Read the evidence fully.** The whole error message and stack trace, the first error in the logs (not the last), the failing assertion's expected vs actual. 3. **Check what changed.** `git log -p --since=<date> -- <path>`, recent dependency updates, config or environment differences. For a known good commit, `git bisect run <test command>`. 4. **Form one hypothesis** that explains all the evidence. State it in one sentence. 5. **Test the hypothesis cheaply:** a log line, a breakpoint, a minimal script, or a failing unit test. Confirm or discard it. Never change two things at once. 6. **Trace to the root.** Ask why the bad value or state exists, and keep asking until you reach the place where it was first wrong. Fix there, not where it crashed. …

How to install
mdr add wst2002/claude-code-skills/bug-debugger@sha256:65f66fc179e6dcedThe line at the top of this page pins the label git:20261016.55bd98a, 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.
