Consumer-impact discipline for contract changes — enumerate every consumer, flag the ones that degrade silently, verify one downstream path end-to-end before shipping. INVOKE PROACTIVELY when a change alters anything other code reads — return shapes, payloads, DB columns, telemetry fields, config values — or renames a published identifier. Skip purely internal changes and strictly additive optional fields. (Schema seams: [[safe-migrations]]; downstream verification: [[tdd]].).

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

# Blast Radius — who reads the thing you're changing?

A change can be locally correct, fully tested, and still break production — because the correctness of a *producer* says nothing about the assumptions of its *consumers*. And the most expensive version of that break isn't the loud one; it's the silent one, where a downstream `catch` or fallback converts the breakage into missing data that nobody notices for weeks, long after the deploy that caused it has stopped being a suspect. This skill exists to make "who reads this?" a mandatory step in the change, not an instinct you hope the author has.

## When to apply this

Apply it the moment a change alters the **shape, format, semantics, or published identity of anything consumed outside the edited code**: a function's return value or type, an API or tool response body, a serialized payload, a database column other code reads, a log or telemetry field, an event or queue message, a config value or env var, CLI/stdout output that anything parses, or an identifier a caller addresses by name (a tool, route, or command). Wrapping counts. Renaming counts — a field or an identifier. Adding an envelope around existing data counts — the…

How to install

The exact contents, by fingerprint
mdr add prabhdeepsingh/claude-plugins/blast-radius@sha256:88627d5d1ef0be31

The line at the top of this page pins the label git:20260826.3bb29a7, 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.
