Summary
This turns Claude into something that can actually execute actions instead of just telling you what to run. Send real emails through Gmail, create GitHub issues, post Slack messages, update Notion pages. You run a one-time setup that connects to Composio's platform, authorize apps via OAuth as needed, then just ask Claude to do things and they happen. The 1000+ app claim is ambitious but the core use case is solid: you're pair programming and want Claude to file that bug, email that update, or ping the team without leaving your editor. Works best when you're already deep in flow and context switching would break your concentration.

How It Works
- You ask Claude to do something
- Composio Tool Router finds the right tool
- First time? You'll authorize via OAuth (one-time)
- Action executes and returns result
Troubleshooting
- "Plugin not found" → Make sure you ran
/plugin install composio-toolrouter - "Need to authorize" → Click the OAuth link Claude provides, then say "done"
- Action failed → Check you have permissions in the target app
