Use when asked to determine what a change could break before it ships. Not for remote, credential, publish, deploy, or irreversible changes.

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

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Determine what a change could break. |
| Authority | Reversible local: writes only one local proof script or test; rollback is deleting it after the report. No remote mutation. No VCS, credential, or published mutation. |
| Side effect | May write and run one proof. |
| Done | Confirmed risks, cleared items, and cheapest pre-merge test. |

## Inputs

A diff, branch, or set of changed files to analyze. The change must be readable from the working tree or a supplied patch. Optional: the running application for in-app reproduction.

## Procedure

1. Read the change completely: the diff, the symbols it adds, changes, and deletes, and what it now does differently, including behavior the diff does not spell out. Done when: the full change is understood beyond the diff surface.
…

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/blast-radius@sha256:2f7c352f37e48e5b

The line at the top of this page pins the label git:20260912.5c5b759, 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.
