Guides an agent through writing a good SKILL.md, covering the name, a description that triggers at the right time, concise instructions, bundled scripts and tests. Use when the user asks to create, improve or review an agent skill, or wants to turn a repeated task into a reusable skill.
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 author A skill is a folder with a `SKILL.md` file. The agent reads the name and description of every installed skill and loads the full instructions only when a task matches. The description is therefore the most important line. ## When to use - The user keeps repeating the same kind of task and wants it captured. - The user has a draft skill that never triggers, or triggers at the wrong time. - A skill needs a review before it is shared. ## Workflow 1. **Collect real examples.** Ask for two or three actual requests the skill should handle, and one it should not. 2. **Pick the name.** Lowercase letters, digits and single hyphens, at most 64 characters, same as the folder name. 3. **Write the description.** Third person, what it does and when to use it, under 1024 characters, no angle brackets.

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.
