# marketplace-author

Adds, removes, and updates plugin entries in the holocron marketplace manifest.

## What it does

Manages entries in the `plugins[]` array of `marketplace.json`. Always updates both `.claude-plugin/marketplace.json` and `.github/plugin/marketplace.json` in the same edit pass — never one without the other. Routes automatically to add, remove, update, or create-from-scratch based on whether the files exist and whether the named plugin is already in the catalog. Runs `claude plugin validate .` after every mutating operation.

## Before you start

Have ready: the plugin name (kebab-case), what you want to do (add/remove/update), and — for add — the source type and source value. If adding from an external repo, know the source type (local path, GitHub, git URL, or npm).

## Usage

```
/marketplace-author
```

No manual script. This skill is purely agentic — it reads, edits, and writes the marketplace files directly using the Read/Edit/Write tools.
