Critically audit or explicitly trim an existing agent skill to its behavioral core, including narrowing over-broad trigger metadata. Use when the user asks to cut, simplify, shorten, de-slop, or reduce the context cost or trigger aggressiveness of a SKILL.md or skill folder. Do not trigger merely because a skill is long or is being edited for another purpose.
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
# Skill Cutter Reduce context cost and accidental activation without weakening the behavior the skill exists to provide. Treat line count as evidence, not the objective. ## Choose the mode - **Audit:** When asked to review, critique, or identify cuts, inspect and report without editing. - **Cut:** An explicit request to cut, trim, shorten, simplify, or de-slop the skill authorizes local edits within that skill. It does not authorize commit, push, publication, or changes to consumers outside the requested scope. ## Find the behavioral core Read the complete `SKILL.md`, its UI metadata, and only the directly relevant resources. Identify the concrete tasks that should trigger it and the decisions an otherwise capable agent would get wrong without it. Classify material before cutting. Use acceptance force as well as content class so useful advice does not survive as accidental governance: | Acceptance force | Treatment | | --- | --- | | Invariant | Keep explicit and narrow. | | Action-required | Keep only for the named task type. | | Risk-triggered gate | Name the triggering risk and proportional proof. | …

How to install
mdr add swyxio/skills/skill-cutter@sha256:87cfe2588ee9c949The line at the top of this page pins the label git:20260822.a6cb86f, 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.
