At a glance

Connects an agent to 1000+ external apps through the Composio Tool Router plugin, so it can actually send emails, create issues and post messages instead of only drafting them.

  • Works in 3 steps: Install the Plugin → Run Setup → Try It!
  • Sending an email from the agent instead of only drafting it
  • SKILL.md covers Quick Start, What You Can Do, Supported Apps and How It Works, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

This skill sets up the composio-toolrouter plugin so the agent can take real actions in outside services rather than only producing text about them. Setup means installing the plugin with /plugin install, running its setup command, which asks for a free Composio API key and takes about a minute, then restarting Claude Code and sending a test email to confirm the connection works.

Once connected, a request such as emailing a contact, creating a GitHub issue, posting to a Slack channel or adding meeting notes to Notion goes to the Composio Tool Router, which picks the right tool. The first use of each app asks you to authorize through OAuth, after which the action runs and returns a result. Listed app groups include email (Gmail, Outlook, SendGrid), chat (Slack, Discord, Teams, Telegram), development (GitHub, GitLab, Jira, Linear), documents (Notion, Google Docs, Confluence) and data (Sheets, Airtable, PostgreSQL). Troubleshooting covers a missing plugin, a pending authorization, and failed actions caused by permissions in the target app.

When your agent uses it

  • Sending an email from the agent instead of only drafting it
  • Creating a GitHub issue or posting a Slack message from a prompt
  • Adding notes or records to apps such as Notion or Airtable

Example prompts

  • “Send an email to sarah@acme.com about the launch.”
  • “Create a GitHub issue titled fix login bug in our web repo.”
  • “Post to the #general Slack channel that the deploy is complete.”
  • “Add these meeting notes to Notion.”

Requirements

  • A free Composio API key
  • The composio-toolrouter plugin
  • OAuth authorization for each app on first use

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Install the Plugin
  2. Run Setup
  3. Try It!

What it can do on your machine

Read from SKILL.md and the folder at commit be2a406. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • platform.composio.dev
    • img.shields.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Connect Apps with Composio loads about 557 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~557

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 228 words (~557 tokens).

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