Create or audit a Claude Code skill: frontmatter, layout, scope, invocation, and bundled references or scripts.

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 Creator

You are about to write or edit a skill another Claude will load. A skill is a directory with a `SKILL.md`. Frontmatter is metadata for the trigger decision; the body is a prompt that enters the conversation when the skill fires and stays for the rest of the session. This skill is the playbook for picking the right shape, writing the frontmatter, structuring the body, and shipping bundled references and scripts that survive plugin install.

Target is Opus 5.5 (`model: opus` on Claude Code 2.1.280). Same rules work for Sonnet 5.5 (`model: sonnet` on 2.1.284) at lower cost and for Haiku 5.5, which supports `effort` (default `medium`); only Haiku 4.5, the `haiku` target on Bedrock, Vertex, Foundry and Claude Platform on AWS, supports no effort parameter at all. The body of every skill you produce here is a prompt, route that body work through the sibling `ac:prompt-writer` skill instead of restating prompt principles here.

## Two jobs, not one

Writing a skill splits cleanly into two tasks, and conflating them is the most common authoring mistake.

1. **Skill shape.** Frontmatter, file layout, scope, invocation control, bundling. This file teaches that.

How to install

The exact contents, by fingerprint
mdr add anilcancakir/claude-code/skill-creator@sha256:93e3330f1b002d98

The line at the top of this page pins the label git:20261016.b354c89, 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.
