Use to drive a bug fix from first report through close, with a "why didn't we catch it?" loop at the end. Triggers — "/engineer.fix", "a bug came in", "this is broken", "a user reported X", "there's a defect", "we have a regression", "this needs a fix", "another report", "more issues", "still failing", "validation failed again", "another bug", "next defect", "more fixes".
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
# fix The defect unit-of-work — parallel to "feature" in the DAE pipeline. Tracks a bug from first report through a regression spec, code fix, hardening, and a structured retrospective that feeds back into the methodology. Unlike ad-hoc fixes, the `fix` workflow enforces a regression spec that must be RED on current code before any change, and closes the loop with a "why didn't we catch it?" gap analysis tied to a closed category vocabulary. That loop is the methodology contribution: bugs become methodology feedback, not just patches. ## When to use - A bug report arrives (user report, Sentry alert, stack trace, regression in CI). - A defect needs a repeatable reproduction path and a tracked fix. - A regression must be proven to stay fixed (the bug-line gate: the regression test must fail on the original bug). **Not for:** building a new capability (`/engineer.discuss` or `/engineer.feature-init`); adjusting an in-flight feature's scope (`/engineer.feature-edit`); reviewing recent changes without a defect (`/engineer.arch-check` or `/crap-analyzer`). …

How to install
mdr add swingerman/engineer/fix@sha256:bd464dbb203098a4The line at the top of this page pins the label git:20261020.8018f96, 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.
