Builds and revises a complete skill DIRECTORY — SKILL.md, scripts, references, assets — and packages it. Use for "create a skill for X", "turn this into a skill", "update/improve this skill", "why doesn't my skill trigger", "review this SKILL.md", "package this skill", or when a repeated procedure should become a reusable artifact. Enforces the structure that makes skills work — a concrete procedure rather than a goal statement, an explicit applicability boundary, failure modes with their…
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
# Creating Skills Create portable, reusable expertise that extends Claude's capabilities across contexts. ## What a skill is for — read before writing one A skill is a **procedural anchor**. Measured across 528 paired executions, 65.7% of skill effects come from supplying a usable procedure — setup steps, tool sequence, intermediate checks, pitfalls — and 4.5% from supplying facts the agent lacked (Jiang et al. 2026, arXiv:2608.14036). Three consequences shape every rule below: 1. **The procedure is the deliverable.** A high-level plan of three to five steps measured at 47.7% success against a 50.0% no-skill baseline. The same experience written as a full SKILL.md measured 79.2%. Vagueness scores worse than silence. 2. **Abstraction costs something.** `skill_guidance_misapplied_or_ignored` runs at 0.8% without a skill and **10.0%** with one. A skill that never says when it does not apply has not paid for itself. 3. **Facts are a reference, not a skill.** Writing one is fine. Call it a reference and do not expect it to change behaviour.

How to install
mdr add oaustegard/claude-skills/creating-skill@sha256:14e35eb90f0fdd82The line at the top of this page pins the label v2.3.0, 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.
