buildwithclaude: A Plugin Marketplace and Discovery Hub for Claude Code

Most Claude Code extensions live scattered across individual repos, each with its own install ritual. davepoon/buildwithclaude (3.4k stars, MIT) is both a curated plugin marketplace you can add with one command and a discovery platform that indexes the wider ecosystem — 20k+ community plugins, 4,500+ MCP servers, and 1,100+ plugin marketplaces, all browsable at buildwithclaude.com.

Why This Skill Matters

The repository's own collections cover the full extension surface of Claude Code: 117 agents (specialized experts for Python, Go, DevOps, security, and more), 175 slash commands for automation like /commit and /tdd, 28 event-driven hooks (notifications, git, formatting), 26 reusable skills, and 51 bundled plugins grouped by category. That breadth makes it a one-stop shop when you want to extend Claude Code without auditing ten separate repos first — and because everything ships as plugins, uninstalling is as clean as installing.

The web UI is half the value: search across every plugin type, filter by category, copy install commands with one click, and read full usage docs before committing to an install.

Installation

Add the marketplace from inside Claude Code:

/plugin marketplace add davepoon/buildwithclaude

Then install what you need — named plugins, or a full category:

/plugin install agents-python-expert@buildwithclaude
/plugin install commands-version-control-git@buildwithclaude
/plugin install all-hooks@buildwithclaude

Manual installation is documented too, for when you want files without the marketplace layer:

git clone https://github.com/davepoon/buildwithclaude.git
cd buildwithclaude
find plugins/agents-*/agents -name "*.md" -exec cp {} ~/.claude/agents/ \;

Restart Claude Code after a manual install.

Real Workflow: Assemble a Python Project Kit

You are starting a Python service and want expert review, commit discipline, and notification hooks from one source.

1. Add the marketplace and install the pieces:

/plugin install agents-python-expert@buildwithclaude
/plugin install commands-version-control-git@buildwithclaude
/plugin install hooks-notifications@buildwithclaude

2. Work as usual — the Python expert agent appears in your agent list, /commit and friends join your slash commands, and the hooks fire on their configured events.
3. When a piece does not earn its keep, uninstall that plugin instead of hunting down loose files.

Real Workflow: Use It as a Discovery Engine

Before writing your own skill or MCP config, search the hub. The web UI indexes the community ecosystem — plugin marketplaces and MCP servers beyond this repo — and /plugin search @buildwithclaude queries the marketplace from the terminal. Copy the install command from the UI rather than reconstructing it by hand.

Tips

• The category bundles (all-agents, all-commands, all-hooks) are convenient for evaluation but defeat the point of curation for daily work — install the specific plugins you verified.
• The manual find ... -exec cp route drops files straight into ~/.claude/agents/ and ~/.claude/commands/ — useful on machines where the marketplace flow is unavailable.
• Counts in the README (117 agents, 175 commands, and so on) describe the curated in-repo collections; the 20k+ and 4,500+ figures are the indexed community ecosystem, a different thing.

When Not to Use This

This is a Claude Code hub — the agents, commands, and hooks target Claude Code's extension formats specifically. If you are not on Claude Code, the discovery UI is still useful for finding MCP servers and marketplaces, but the installable artifacts will not transfer. And if you only need one narrow capability, installing a single focused skill repo beats pulling in a 51-plugin catalog.
