Build with Claude

What it does

• Own marketplace collections: 117 agents across 11 categories, 175 commands across 22 categories, 28 hooks across 8 categories, 26 skills, and 51 bundled plugins
• Ecosystem discovery index: 20,000+ community plugins, 4,500+ MCP servers, and 1,100+ plugin marketplaces from the wider ecosystem
• Web UI at buildwithclaude.com: search, filters, one-click copy of install commands, docs and usage examples per entry
• Plugins follow the standard agent/command/hook markdown format, so entries work as reading material for writing your own

When to use it

The front door for "where do I find extensions": browse before building your own, and install curated bundles (agents-python-expert, hooks-notifications) instead of hand-copying files. The indexed MCP server list doubles as an MCP discovery panel.

Getting started

# Add the marketplace, then install from it
/plugin marketplace add davepoon/buildwithclaude
/plugin install agents-python-expert@buildwithclaude

# Or install everything in a collection
/plugin install all-commands@buildwithclaude

Things to know

Index numbers are the platform's own counts and grow with the ecosystem — treat them as scale signals, not exact inventory. Community-contributed plugins vary in quality; read a plugin's source before installing it into a real repo.
