Author, structure, verify, and publish a high-quality agent skill (SKILL.md). Use whenever the user wants to "write a skill", "create a skill for X", turn expertise or a workflow into a reusable skill, improve an existing SKILL.md, or publish a skill to their repo. Covers the SKILL.md format, writing a strong description, progressive disclosure with reference files, the detect-context-first pattern, fact-verification discipline, testing, and the publish workflow.
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 - write a great, publishable skill A skill is a `SKILL.md` file (YAML frontmatter + markdown instructions) that an agent loads when its work matches. Optionally it bundles supporting files (`references/*.md`, `scripts/`) loaded on demand. Good skills are **specific, accurate, and lean**. This skill is how to write one. ## 1. Decide it should exist Write a skill when there's real, reusable know-how an agent would otherwise get wrong or generic: a framework's version-specific rules, a migration's gotchas, a self-hosting workflow, a house style. **Don't** write one for a one-off task, or for something the model already does well. Check the ecosystem first (`npx skills find <topic>`) - if a great one exists, install it instead; if only generic ones exist, that's your gap. ## 2. Frontmatter - name + description (the description is critical) ```yaml --- name: kebab-case-name # matches the folder name description: <what it does> + <when to use it> + <trigger phrases> + <when NOT to use> --- ``` …

How to install
mdr add majdghithan/agent-skills/skill-authoring@sha256:9ce08e82a2450370The line at the top of this page pins the label git:20260729.68e840f, 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.
