## What it does

The skill gives an agent a gateway-based way to work with connected external apps. It can search for a tool that matches a task, fetch the tool’s full parameter schema, and execute the call. That covers actions such as sending Gmail mail, creating a Calendar event, or opening a GitHub issue.

Its documented operations also cover listing connections and starting a new OAuth connection. The gateway handles Composio authentication and API key storage, while the agent uses its HTTP API rather than calling the SDK. Keep this traffic off proxies: proxying changes the caller identity and can make connection or execution requests fail.

## Requirements
- Works with: GitHub, Slack, Gmail
