Use when changing a shared contract — a flag, column, enum/union member, shared type, exported symbol, endpoint shape, or config key. The retired name is the cheapest complete index of consumers: grep the whole workspace and run every suite that crosses the boundary, not just the package you edited. Triggers on "rename", "change this type", "add/remove a field", "change the API shape", "update shared config", "who uses this", "will this break anything", and editing any code imported by more…
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
# Grep the Blast Radius of a Contract Change **Type:** Open-source — client-agnostic methodology, no project-specific detail. **Created by akbarsha — https://github.com/iamakbarsha1** Distilled from repeated cases where a shared contract changed, the edited package's tests stayed green, and sibling consumers broke silently. **Licence:** Released under CC BY 4.0 — share and adapt for any purpose with credit. Full text: `LICENSE` at the repository root. **Feedback & Support:** If a rule here proves wrong or needs sharpening, open an issue on the repository or contact the author at the profile link above. If the problem is the agent not following a rule below rather than the rule itself, that's an execution failure — acknowledge and correct it. ## The core rule Verification scope follows the contract, not the diff. When you change something shared, the OLD name (the field you renamed, the enum member you removed, the flag you retired) is the most complete index of its consumers that exists. Grep for it across the ENTIRE workspace — source, tests, e2e scripts, other apps, generated code, docs that assert behaviour — before you …

How to install
mdr add iamakbarsha1/whetstone/grep-the-blast-radius@sha256:4ac28b9a9a74a499The line at the top of this page pins the label git:20261019.5842640, 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.
