Use when creating, restructuring, reviewing, or retiring an agent 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 authoring ## Overview Keep agent workflows discoverable, independently loadable, concise, and current. ## When to Use Use when a durable repository rule needs a new skill or an existing skill is stale, duplicated, or too large. ## When NOT to Use Do not use for session notes, progress reports, issue ledgers, speculative features, or one-off task instructions. ## Core Process 1. Search `../../SKILL.md` and existing skills for an owner. 2. Create a directory named with lowercase hyphenated words. 3. Add `SKILL.md` with YAML `name` and `description` front matter. 4. Use the standard sections: Overview, When to Use, When NOT to Use, Core Process, Red Flags, Verification, References. 5. Keep the entry file below 500 lines and preferably below 1,500 tokens. 6. Move detailed facts to a directly linked reference file. 7. Update the router table in `../../SKILL.md`. 8. Add the skill-improvement write-back for the area in the same commit. 9. Validate links, front matter, size, and source accuracy. Use standard GFM Markdown. MCP does not define a skill filesystem layout; this layout follows the Agent Skills convention. ## Common Rationalizations …

How to install
mdr add projectbluefin/website/skill-authoring@sha256:5e4a9fba71624e6bThe line at the top of this page pins the label git:20260819.e0b2fe2, 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.
