Author, lint, and publish skill packages that satisfy the library authoring standard. Use when creating a new skill, reviewing a skill PR, or fixing one that never activates.
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
# Write A Skill The meta-skill for building skill packages. It turns `standards/skill-authoring-standard.md` from a document you agree with into a gate you can run: scaffold the package, write a description that actually activates, place content in the right file, and lint against all 11 patterns before anyone reviews it. Most rejected skills fail on two things — a description nothing matches, and a SKILL.md carrying content that belonged in `references/`. ## When to use this skill - **Creating a new skill** from a one-line idea and needing the package structure right the first time - **Reviewing a skill PR** and wanting a mechanical pass before spending attention on judgement - **Fixing a skill that never activates** despite being well written — almost always a description problem - **Splitting an oversized SKILL.md** that has crept past 500 lines - **Auditing a whole domain** for description collisions after adding several neighbouring skills - **Onboarding a new author** who needs the standard operationalised rather than explained ## Inputs the skill expects - The skill's one-sentence purpose and the domain directory it belongs in …

How to install
mdr add borghei/claude-skills/write-a-skill@sha256:589200051f764790The line at the top of this page pins the label v1.0.0, 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.
