Create or refactor high-quality skills with lean frontmatter, progressive disclosure, and optional bundled helpers. Use when authoring reusable agent workflows.
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 Guide Use this skill when creating or improving a reusable skill. ## What Good Skills Do - Trigger reliably from `name` and `description` — the description must be specific enough to avoid false triggers. - Stay short in `SKILL.md` and move bulk detail into `references/` or `scripts/`. - Teach a **workflow or decision pattern**, not just dump background information. - Include scripts or references only when they eliminate repeated work or prevent ambiguity. ## Frontmatter Template ```yaml --- name: kebab-case-matching-directory-name description: Use when [trigger condition]. Does [what it does]. [Optional: NOT for X.] --- ``` ## Body Format Default to a pure Markdown body after the YAML frontmatter. Use headings such as `## Purpose`, `## When to Use`, `## Workflow`, and `## Verification`. Do not use XML-like tags such as `<Purpose>`, `<Workflow>`, or `<Use_When>` as normal top-level sections. XML-like tags are acceptable only when they strictly delimit nested examples, quoted input, external documents, or machine-readable prompt payloads. **Good description** (specific, trigger-clear): ``` …

How to install
mdr add yeaight7/agent-powerups/skill-authoring-guide@sha256:e9475f70e4ebd68fThe line at the top of this page pins the label git:20260606.80db1e0, 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.
