Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.
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
# Surgical patch Reproduce failure first when economical; otherwise capture strongest available evidence. - Trace symptom to responsible mechanism. - Change narrowest layer that owns incorrect behavior. - Preserve unrelated behavior and user changes. - Avoid cleanup, renaming, and abstraction outside fix. - Add only regression proof relevant to task. Run focused proof plus nearest affected gate. Stop when failure is fixed and regression proof passes.

How to install
mdr add juliusbrussee/caveman/surgical-patch@sha256:81ea9f7b51409970The line at the top of this page pins the label git:20260811.82864c8, 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.
