composio
Use 1000+ external apps via Composio - either directly through the CLI or by building AI agents and apps with the SDK
Why this skill is useful
Adds specific CLI commands and SDK integration patterns for automating interactions with over 1000 external apps that the AI wouldn't reliably generate on its own.

What this skill does
When to Apply User wants to access or interact with external apps (Gmail, Slack, GitHub, Notion, etc.) User wants to automate a task using an external service (send email, create issue, post message) Building an AI agent or app that integrates with external tools Multi-user apps that need per-user connections to external services Setup Check if the CLI is installed; if not, install it: After installation, restart your terminal or source your shell config, then authenticate: For agents without direct browser access: composio login --no-wait jq to get URL/key, share URL with user, then composio login --key <clikey> --no-wait once they complete login. --- 1. Use Apps via Composio CLI Use this when: The user wants to take action on an external app directly — no code writing needed. The agent uses the CLI to search, connect, and execute tools on behalf of the user. Key commands (new top-level aliases): composio search "<query>" — find tools by use case composio execute "<TOOLSLUG>" -d '{...<input params>}' — execute a tool composio link [toolkit] — connect a user account to an app (agents: always use --no-wait for non-interactive mode) composio listen — listen for real-time trigger events Typical workflow: search → link (if needed) → execute Full reference: Composio CLI Guide --- 2. Building Apps and Agents with Composio Use this when: Writing code — an AI agent, app, or backend service that integrates with external tools via the Composio SDK. Run this first inside the project directory to set up the API key: Full reference: Building with Composio
