Add Plugin

Add a new plugin to the marketplace by updating .claude-plugin/marketplace.json, .cursor-plugin/marketplace.json and README.md.

The user will provide: plugin name, source (GitHub repo, relative path, or npm package), and a short description.

Steps:

1. Read .claude-plugin/marketplace.json
2. Add a new entry to the plugins array with name, source, and description
3. Use kebab-case for the plugin name
4. For GitHub sources use: { "source": "github", "repo": "owner/repo" }
5. For local plugins use a relative path starting with ./
6. Write the updated .claude-plugin/marketplace.json

6b. Read .cursor-plugin/marketplace.json. Add the same entry to its plugins array. Write the updated .cursor-plugin/marketplace.json

1. Read README.md
2. Update the README ## Plugins section (or create it after ## Install and before ## Usage). Each plugin is rendered as a ` dropdown. Count the number of skills/*/SKILL.md` files in the plugin directory to determine the skill count. Use this format:

plugin-name (N skills) — Short plugin description.

Claude Code: `/plugin install plugin-name@leadership-skills`

| Skill | Purpose |
|-------|---------|
| `skill-name` | Skill description. |

Use "1 skill" (singular) when count is 1, "N skills" (plural) otherwise. If the plugin has no skills yet, use "(0 skills)".

1. Update the total skill count in the subtitle line (e.g. 11 leadership skills for Claude Code, Cursor, and Claude Cowork.). Count all skills/*/SKILL.md files across all plugin directories to get the new total.
2. Write the updated README.md

If $ARGUMENTS is provided, treat it as the plugin name or GitHub repo to add.
