Shape code changes and PR stacks so each diff is easy to review: one local claim, one safety invariant, clear architectural effect, and an explicit reason for the slice. Trigger before authoring implementation work, PR stacks, or any multi-diff plan, or when asked to split/scope/compress a change into reviewable pieces.
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
# split-scope Use this skill before authoring implementation work, PR stacks, or any multi-diff plan. Optimize for reviewer cognition, not smallest total patch. ## Core Rule Each diff or workflow should make one locally reviewable claim. A tired senior engineer should be able to answer: - What architectural thing changed? - Why does this slice exist? - Why is it safe? - What alternatives were rejected? ## Required Metadata Every implementation slice should carry these fields in task descriptions and PR bodies: - `Review claim:` one sentence the reviewer is being asked to approve. - `Review lane:` exactly one lane from your `drafter.config.json` taxonomy (default: `behavior`, `refactor`, `proof`, `cleanup`, `policy`, or `docs`). - `Safety invariant:` why this slice is safe to review locally. - `Slice rationale:` why this work is split here instead of bundled elsewhere. - `Architectural effect:` what changed in control flow, data flow, ownership, dependency direction, or public surface. - `Alternative considerations:` rejected designs or split shapes. - `Non-goals:` what this slice explicitly does not change. When stacking …

How to install
mdr add edbertchan/catstack/split-scope@sha256:40e046035142430dThe line at the top of this page pins the label git:20260911.568b2b3, 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.
