Create Marketplace

Scaffold a new Claude Code plugin marketplace as a GitHub repo.

Gather info

Ask the user (use AskUserQuestion):

1. GitHub owner/repo — e.g. MyOrg/my-plugins. Repo will be created.
2. Marketplace name — short slug (no claude/anthropic in name — blocked by validation). e.g. won-plugins, acme-tools.
3. Description — one-line.
4. Visibility — public or private.

Scaffold

1. Create local directory

/tmp/<marketplace-name>/
├── .claude-plugin/
│   └── marketplace.json
└── README.md

2. Write .claude-plugin/marketplace.json

{
  "$schema": "https://anthropic.com/claude-code/marketplace.schema.json",
  "name": "<marketplace-name>",
  "description": "<description>",
  "owner": {
    "name": "<user name from git config>",
    "url": "https://github.com/<owner>"
  },
  "plugins": []
}

Validation rules (will fail install if violated):

• name must NOT contain claude, anthropic, or official (case-insensitive).
• name should be kebab-case.
• plugins array starts empty — plugins added via /plugin:create-plugin.

3. Write README.md

Include: marketplace name, install commands (/plugin marketplace add <owner>/<repo>), table of plugins (empty initially), "Adding a plugin" section.

4. Git init + push

cd /tmp/<marketplace-name>
git init && git add -A
git commit -m "feat: initial marketplace scaffold"
gh repo create <owner>/<repo> --<visibility> --source=. --push \
  --description "<description>"

5. Register locally

Tell user to run:

/plugin marketplace add <owner>/<repo>

6. Report

Print: repo URL, next step (/plugin:create-plugin to add first plugin).
