composio SKILL.md skillB
composio from starchild-ai-agent/official-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add starchild-ai-agent/official-skills/composio@v1.4.1Pins v1.4.1 in mdr.lock. Pin the fingerprint instead.

Composio gateway: act on 1000+ connected apps like Gmail, Slack, GitHub, Calendar. Use when the user wants to act in a connected SaaS app (e.g. send Gmail, create Notion page, add Calendar event, open a GitHub issue).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Composio — External App Integration via Gateway
Composio lets users connect 1000+ external apps (Gmail, Slack, GitHub, Google Calendar, Notion, etc.) to their Starchild agent. All operations go through the **Composio Gateway** (`composio-gateway.fly.dev`), which handles auth and API key management.
## Architecture
```
Agent (Fly 6PN network)
↓ HTTP (auto-authenticated by IPv6)
Composio Gateway (composio-gateway.fly.dev)
↓ Composio SDK
Composio Cloud → Target API (Gmail, Slack, etc.)
```
- **You never touch the COMPOSIO_API_KEY** — the gateway holds it
- **You never call Composio SDK directly** — use the gateway HTTP API
- **Authentication is automatic** — your Fly 6PN IPv6 resolves to a user_id via the billing DB
- **No env vars needed** — the gateway is always accessible from any agent container
## Gateway Base URL
```
GATEWAY = "http://composio-gateway.flycast"
```
All requests use **plain HTTP over Fly internal network** (flycast). No JWT needed.
**CRITICAL — never route the gateway through sc-proxy:**
- Use **curl** (as in the examples below) or plain `requests` / `http.client` with **no proxy**.

How to install
mdr add starchild-ai-agent/official-skills/composio@sha256:2ef89a264f4d70f3The line at the top of this page pins the label v1.4.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
