What problem does it solve? Connecting AI agents and applications to external services like Gmail, Slack, GitHub, and Notion normally requires writing custom OAuth flows, API clients, and credential management for each service. This Skill provides a unified way to search, authenticate, and execute tools across 1000+ apps through the Composio CLI or SDK. ## Core Features & Use Cases - CLI Tool Execution: Search for tools, link user accounts via OAuth, and execute actions (send emails, create issues, post messages) directly from the terminal with no code. - SDK for Agents and Apps: Build AI agents with Tool Router sessions, per-user authentication, triggers, and framework integrations for LangChain, Vercel AI SDK, OpenAI Agents, and Mastra. - Use Case: An agent needs to send an email on behalf of a user. It runs composio search "send an email", links the user's Gmail account if needed, then executes GMAIL_SEND_EMAIL with the message data. ## Quick Start Ask the agent to search Composio for the action you need, connect the relevant app account, and execute the tool on your behalf.
