Scaffold a new Claude Code skill into this plugin (or the current project). The user names the skill and picks a category — agent review, visualizer, documentation, other — and the matching SKILL.md template lands on disk, ready to edit.

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

# Add a new skill

The user typed `/overture:add-skill $ARGUMENTS`. Walk them through creating
the skill end-to-end.

## 1. Validate the name

The first argument is the skill slug. It must match the shape
`[a-z0-9][a-z0-9._-]*` (lowercase letters, digits, dot, dash, underscore;
starts alphanumeric; up to 64 chars). If no argument was passed, OR the
first argument fails that shape, say so and stop — do not guess a name.

If the slug already exists under the target skills directory (see step 3),
tell the user and stop. Do not overwrite.

## 2. Pick a category

The second argument, if present, is the category. If absent OR it is not
one of the four values below, use the `AskUserQuestion` tool to ask:

> **"Where should this skill live? (category drives the SKILL.md template)"**

- **agent-review** — a reviewer skill (code / design / security pass)
- **visualizer** — a skill that returns a Mermaid diagram or an HTML mock
- **documentation** — a skill that writes or updates docs
- **other** — a generic skill (recommended if none of the above fit)

Record the chosen value as the `category` for step 4.

## 3. Pick the target directory

How to install

The exact contents, by fingerprint

mdr add mikeheid/overture/add-skill@sha256:7c851b57f919a3b0

The line at the top of this page pins the label git:20261008.d87e89b, 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.
