Adding a Plugin

1. Create plugins/<plugin-name>/ with .claude-plugin/plugin.json
2. Add TypeScript source in src/, skills in skills/
3. Run bun run build to generate dist/
4. Register in .claude-plugin/marketplace.json under plugins

Adding a Shared Package

1. Create packages/<package-name>/ with package.json (name: @agent-extensions/<name>)
2. Add source in src/ and create @public-index.ts as the entry point
3. Add rslib.config.ts for building
4. bun run build will auto-generate the exports field in package.json from @public-*.ts files
5. Reference from plugins via "@agent-extensions/<name>": "workspace:*" in their package.json
