connect-apps is a skill that connects Claude to Gmail, Slack, GitHub, and 1000+ apps via Composio so the agent can execute real actions.
About
connect-apps wires Claude to external services through the Composio Tool Router plugin so actions execute in real apps instead of generating text-only instructions. Setup installs the composio-toolrouter plugin, runs /composio-toolrouter:setup with a free platform.composio.dev API key, and restarts Claude Code before testing with a live email send. Supported surfaces include Gmail, Outlook, Slack, Discord, GitHub, GitLab, Jira, Notion, Google Sheets, Airtable, PostgreSQL, and over one thousand additional integrations. The workflow is ask Claude for an action, Tool Router selects the tool, first-time OAuth authorization opens once per app, then the action returns a result. Example commands cover sending email, creating GitHub issues, posting Slack messages, and adding Notion meeting notes. Troubleshooting addresses missing plugin install, pending OAuth authorization, and permission failures in the target app. Developers use it when they want agent-driven cross-app automation without building custom OAuth clients for every service.
