This is a monorepo containing multiple independent plugins. Each plugin:

• Lives in its own directory (css-development/, firebase-development/, etc.)
• Has its own .claude-plugin/plugin.json configuration
• Contains its own skills, docs, and tests
• Can be installed independently

See [CLAUDE.md](CLAUDE.md) for developer documentation on the monorepo structure and conventions.
