composio

composio is a skill for Claude Code from melandlabs/openloomi. It costs 31 tokens per session (553 once invoked), scanned C, original, Apache-2.0.

A connection layer for using more than 1,000 external apps through the Composio command line or software library. External apps include services such as Gmail, Slack, GitHub, and Notion.

In plain words
What is it for?
Use it to search for app actions, connect accounts, perform tasks in external services, or build agents and apps that use those services.
Why use it?
It lets an agent connect to outside services and carry out tasks without building a separate integration for each one.

About the project

OpenLoomi is an open-source desktop AI coworker that connects work tools, gathers context, and highlights decisions or actions needing attention. It is for people managing work across multiple apps, and its catalogue add-ons extend the resident desktop for agent frameworks such as Claude Code, Codex, OpenCode, Hermes, and OpenClaw.

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Supply Chain · line 18
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
  • high Tool Misuse · line 18
    Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.
    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.

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 C, and why

composio scanned grade C with 2 findings 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 9d ago.

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.

What it actually says

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:

curl -fsSL https://composio.dev/install | bash

After installation, restart your terminal or source your shell config, then authenticate:

composio login       # OAuth; interactive org/project picker (use -y to skip)
composio whoami      # verify org_id, project_id, user_id

For agents without direct browser access: composio login --no-wait | jq to get URL/key, share URL with user, then composio login --key <cli_key> --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 "<TOOL_SLUG>" -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

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:

composio init

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
