Write a code fix for a bug. Use before writing any fix, whichever workflow you are running.
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
# Fixing a bug The gates every fix attempt clears, whichever workflow you are running. ## Required skills - Load `/tend-ci-runner:propose-instructions` if the fix edits a skill or instruction file. - Load `/tend-ci-runner:push-commits` before reviewing the fix for a push. ## Reproduce first 1. **Understand the report** — What command was run? What was expected? What actually happened? 2. **Find relevant code** — Search the codebase for the functionality described. 3. **Write a failing test** — Add a regression test that demonstrates the bug, following the repository's test organization. 4. **Run the test** to confirm it fails. Use the test commands from the project's instruction files. Generally, have a failing test before writing a fix. A passing attempt does not establish that an intermittent failure is resolved; compare the failing conditions and continue the investigation. **Only attempt a fix if all of these hold:** - Bug is clearly reproducible (usually, the test written above fails) - Root cause is understood - Confident the fix is correct ## Retain engineering ownership …

How to install
mdr add max-sixty/tend/fix-a-bug@sha256:762f716bbde27652The line at the top of this page pins the label git:20261030.96248a6, 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.
