Investigate and fix bugs, errors, or unexpected behavior systematically — reproduce, locate, understand the root cause, fix it, and add a regression test. Use this skill when the user reports a failure (test, runtime, build, CI), shares a stack trace or error message, says something doesn't work, asks why something is broken, or asks for a fix that requires diagnosis — even when the word "debug" is not used (e.g. "this is broken", "why is it failing", "X doesn't 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
# Debug Systematically find and fix the root cause of a bug. ## Steps 1. **Reproduce** — Get the exact error message, stack trace, or steps to reproduce. Understand what happens vs. what should happen. 2. **Locate** — Narrow down where the problem is: - Read the error message and stack trace — they usually point to the exact location. - Search for relevant keywords (error strings, function names). - Trace the data flow from input to the failure point. 3. **Understand** — Before fixing, understand *why* it fails: - What assumption is violated? - When was it introduced? (`git log`, `git blame`) - Logic error? Data problem? Race condition? Missing edge case? 4. **Fix** — Make the smallest change that correctly addresses the root cause. 5. **Verify** — Write or update a test that catches this bug. Run the full test suite for regressions. 6. **Explain** — Briefly describe what caused it and why the fix is correct. ## Gotchas - Let the error surface until you understand it. A silent try-catch hides the cause and breeds a worse bug later. - Trace to the root cause before applying the fix. Symptom-level patches return as new bugs. …

How to install
mdr add yelmuratoff/exuno/debug@sha256:1e50f261efd10d1cThe line at the top of this page pins the label git:20260728.7c60c81, 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.
