Best practices for writing skills and agents: descriptions, structure, token efficiency, frontmatter, tool scoping, and common authoring mistakes. Activate when creating or editing a SKILL.md, a command file, or an agent file, or when the user asks to "write a skill", "add a command", "create an agent", or "review this 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

# Plugin Authoring

Rules for writing skills and agents. Apply them when creating or editing any of these files.

## Universal Rules

- Assume the model is already smart. Only write what it does not already know: project facts, exact procedures, output contracts. Cut explanations of general concepts. Challenge every line: "does this justify its token cost?"
- Write descriptions in third person, stating both what the artifact does and when to use it. Include the trigger phrases a user would naturally say. Put the key use case first: listings truncate long descriptions.
- Use one consistent term per concept throughout a file. Do not mix synonyms.
- No time-sensitive content. Nothing that becomes wrong on a date.
- Forward slashes in all paths.
- Platform-neutral wording: the same file must read correctly in every editor that loads it. No editor-specific product names or jargon in prose.
- Never reference another plugin file by repo-relative path. The install location differs from the source repo. Invoke skills by name and locate scripts via the plugin or skill root variable.

How to install

The exact contents, by fingerprint

mdr add rashadansari/myagents/plugin-authoring@sha256:e06023d0b7c84156

The line at the top of this page pins the label git:20261014.5b60e38, 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.
