What problem does it solve? AI assistants can normally only generate text about actions, not perform them. This Skill bridges that gap by connecting Claude to over 1000 external applications, so requests like sending an email or creating a GitHub issue actually execute in the target service. ## Core Features & Use Cases - Real Action Execution: Send emails via Gmail or Outlook, post messages to Slack or Discord, and create issues in GitHub, GitLab, Jira, or Linear. - OAuth Authorization Flow: First-time actions trigger a one-time OAuth link so Claude acts with your explicit permission in each app. - Broad App Coverage: Works with email, chat, developer tools, docs (Notion, Google Docs), and data tools (Sheets, Airtable, PostgreSQL). - Use Case: Ask Claude to "Create a GitHub issue for the login bug and post a summary to Slack #engineering" and both actions execute across the two services. ## Quick Start Install the composio-toolrouter plugin, run the setup command with a free Composio API key, then ask Claude to send you a test email.
