"Create GitHub issue: fix login bug"	Creates the issue
"Post to Slack #general: deploy complete"	Posts the message
"Add meeting notes to Notion"	Adds to Notion

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
