Explicitly limit blast radius before any implementation or file 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
# Scope Freeze ## Purpose Prevent uncontrolled changes by defining a narrow, enforceable boundary. This freezes **write scope**, not discovery. ## When to use Immediately before editing files or running state-changing commands. ## Inputs - SPEC.md / PLAN.md / TODO.md - Selected task - Current repo state - Git base used to judge the implementation diff - Optional SPEC implementation diff budget ## Workflow 1. Name the exact task. 2. List **allowed** files/folders as exact paths, directory prefixes, or globs. 3. Do not use repo-wide catch-all patterns (`*`, `**`, `**/*`) in `Allowed writes`. If the task genuinely spans multiple areas, enumerate the narrowest relevant prefixes and set a changed-file budget. 4. List **read-only** files/folders. 5. List **forbidden** paths and operations. 6. Set max files changed and rename/deletion rules when helpful. If SPEC.md has an enforced implementation diff budget, keep the scope's hard file cap at or below that accepted file budget unless scope is renegotiated before implementation. 7. List allowed commands. 8. List compatibility seams and test-integrity triggers before editing. 9. Define clear stop condition. …

How to install
mdr add tmusser/ai-engineering-skills/scope-freeze@sha256:5496ec55cb0f2df4The line at the top of this page pins the label git:20261008.67190ab, 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.
