Instructions onlyProductivity & Workflow
AI-generated overview

Connects an agent to external apps such as Gmail, Slack and GitHub so it can send emails, create issues and post messages.

What it does
This skill walks through installing and configuring a plugin that links the agent to a large set of external services. It covers installing the plugin, running a setup step with an API key, and authorizing apps through OAuth. Once connected, the agent can perform actions such as sending email, creating GitHub issues, posting Slack messages and adding notes to Notion.
When to use it
Use it when the user wants the agent to take real actions in external services rather than only draft text. It fits requests to send emails, create issues, post chat messages or write to connected documents and databases.
Requirements
Requires the plugin to be installed and a setup command to be run, a free API key from the vendor's platform, and OAuth authorization for each target app. Network access is needed. The skill contains instructions only and ships no scripts.

Connect Apps

Connect Claude to 1000+ apps. Actually send emails, create issues, post messages - not just generate text about it.

Quick Start

Step 1: Install the Plugin

/plugin install composio-toolrouter

Step 2: Run Setup

/composio-toolrouter:setup

This will:

  • Ask for your free API key (get one at platform.composio.dev)
  • Configure Claude's connection to 1000+ apps
  • Take about 60 seconds

Step 3: Try It!

After setup, restart Claude Code and try:

Send me a test email at [email protected]

If it works, you're connected!

What You Can Do

Ask Claude to...What happens
"Send email to [email protected] about the launch"Actually sends the email
"Create GitHub issue: fix login bug"Creates the issue
"Post to Slack #general: deploy complete"Posts the message
"Add meeting notes to Notion"Adds to Notion

Supported Apps

Email: Gmail, Outlook, SendGrid Chat: Slack, Discord, Teams, Telegram Dev: GitHub, GitLab, Jira, Linear Docs: Notion, Google Docs, Confluence Data: Sheets, Airtable, PostgreSQL And 1000+ more...

How It Works

  1. You ask Claude to do something
  2. Composio Tool Router finds the right tool
  3. First time? You'll authorize via OAuth (one-time)
  4. Action executes and returns result

Troubleshooting

  • "Plugin not found" → Make sure you ran /plugin install composio-toolrouter
  • "Need to authorize" → Click the OAuth link Claude provides, then say "done"
  • Action failed → Check you have permissions in the target app
