composio

composio is a skill for Claude Code, Codex from yc-software/qm. It costs 49 tokens per session (1,493 once invoked), scanned A, original, MIT.

A guide for using an authorized Composio account, a service that connects software agents to external apps, through its official software library. It covers discovering connected apps, requesting consent, and executing actions while keeping the access key protected.

In plain words
What is it for?
Use it when a valid Composio API key is available and the task requires discovering or performing actions in connected applications.
Why use it?
It helps an agent use existing app connections without exposing credentials or treating a user identifier as an authorization boundary. It also limits actions to accounts the current task is allowed to access.

About the project

QM is a shared work environment for coding agents that gives each employee and conversation an isolated workspace while allowing collaboration in Slack and on the web. Startups use it to run agents for individuals, teams, and company operations, with selectable harnesses and models. The catalogue entries extend QM with skills, instructions, and settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

composio scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- On a `502`, read the JSON body (`cause`, `providerStatus`, `message`); with Python, catch `urllib.error.HTTPError` and read `e.read()`. Back off and shrink the page rather than repeating the same request.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Composio

Use this skill for app discovery, consent, and execution through QM's authenticated backend. Check availability with GET /v1/composio/toolkits; an absent sandbox API key is expected. Never ask regular users to provision a Composio project key.

Show setup in web chat

When the user asks to connect apps, browse integrations, or show setup again in web chat, include the following directive as its own paragraph in your reply, with blank lines around it:

::connect-apps{}

Write the directive directly, without a code fence or quotation. The web UI renders only the searchable app picker in place. To display the separate Add to Slack action, use ::add-to-slack{} as its own paragraph instead. Include both directives in separate paragraphs when the user asks for full setup. The Slack action is available to administrators; other users should ask their administrator to install QM. Do not repeat the welcome or celebration. Rendering the widget does not authorize any service or require an SDK call; the user chooses an app and completes provider consent. Do not claim accounts are connected without verified status. For Slack conversations, use ordinary authorization links instead of this web-only directive.

When a task needs an app that isn't connected

Check connections before work that depends on an app. If the app is in the catalog but not connected, ask for it in your first reply: do any part that doesn't need the app, show the connect option, and stop. Don't finish a long partial answer first.

  • Slack uses its dedicated connection flow even though toolkits lists it. In web chat, use ::link-slack-account{} as its own paragraph for personal Slack access or its connection status. Use ::add-to-slack{} for the separate administrator step of installing the workspace bot, which must be completed first. In Slack conversations, direct the user to QM web Settings (/?view=settings) and Link your Slack account, signed into their existing web account. Never use ::connect-apps{toolkit="slack"} or a generic Slack authorization link. These dedicated widgets do not automatically resume the task; ask the user to reply after connecting.
  • For other apps in web chat, put ::connect-apps{toolkit="notion"} on its own paragraph, using the exact id from toolkits. It shows a single connect button for that app. After consent the user returns to this conversation, the account is verified, and a message is sent so you can continue the task.
  • For other apps in Slack conversations, mint a link with authorize (step 3 below) and say you'll pick the task back up when they reply.
  • If the app isn't in the catalog, say so in one sentence and don't show the picker. Look for the provider's official API or MCP server yourself. If it uses API keys, send a secure keychain drop link instead of asking for the key in chat.
