Choose reusable automation when repeated work or deterministic verification justifies a script or codemod.
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
# Build the lever
Use an existing tool when it performs the requested transformation or check reliably. Build a script or codemod when repetition, error risk, or reproducibility outweighs its implementation and maintenance cost.
A one-off edit can stay manual. A new file is not evidence of better engineering, and citing this principle does not require creating one.
For bulk changes, validate a representative sample before scaling. Prefer a deterministic transformation to agents repeating the same mechanical edit. Keep scripts scoped and safe to rerun.
Preserve useful tools when the task needs them. Committing or installing them requires the user's authorization.
The line at the top of this page pins the label git:20260907.b1269d9, 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.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
