connect
About
The Connect skill enables Claude to execute real actions across 1000+ apps like Gmail, Slack, and GitHub instead of just describing them. Developers should use it when Claude needs to directly send emails, create issues, post messages, or update databases. It transforms Claude from generating text about actions into actually performing them.

Documentation
Connect
Connect Claude to any app. Stop generating text about what you could do - actually do it.
When to Use This Skill
Use this skill when you need Claude to:
- Send that email instead of drafting it
- Create that issue instead of describing it
- Post that message instead of suggesting it
- Update that database instead of explaining how
What Changes
| Without Connect | With Connect |
|---|---|
| "Here's a draft email..." | Sends the email |
| "You should create an issue..." | Creates the issue |
| "Post this to Slack..." | Posts it |
| "Add this to Notion..." | Adds it |
Supported Apps
1000+ integrations including:
- Email: Gmail, Outlook, SendGrid
- Chat: Slack, Discord, Teams, Telegram
- Dev: GitHub, GitLab, Jira, Linear
- Docs: Notion, Google Docs, Confluence
- Data: Sheets, Airtable, PostgreSQL
- CRM: HubSpot, Salesforce, Pipedrive
- Storage: Drive, Dropbox, S3
- Social: Twitter, LinkedIn, Reddit
Setup
1. Get API Key
Get your free key at platform.composio.dev
2. Set Environment Variable
export COMPOSIO_API_KEY="your-key"
3. Install
pip install composio # Python
npm install @composio/core # TypeScript
Done. Claude can now connect to any app.
Examples
Send Email
Email sarah@acme.com - Subject: "Shipped!" Body: "v2.0 is live, let me know if issues"
Create GitHub Issue
Create issue in my-org/repo: "Mobile timeout bug" with label:bug
Post to Slack
Post to #engineering: "Deploy complete - v2.4.0 live"
Chain Actions
Find GitHub issues labeled "bug" from this week, summarize, post to #bugs on Slack
How It Works
Uses Composio Tool Router:
- You ask Claude to do something
- Tool Router finds the right tool (1000+ options)
- OAuth handled automatically
- Action executes and returns result
Code
from composio import Composio
from claude_agent_sdk.client import ClaudeSDKClient
from claude_agent_sdk.types import ClaudeAgentOptions
import os
composio = Composio(api_key=os.environ["COMPOSIO_API_KEY"])
session = composio.create(user_id="user_123")
options = ClaudeAgentOptions(
system_prompt="You can take actions in external apps.",
mcp_servers={
"composio": {
"type": "http",
"url": session.mcp.url,
"headers": {"x-api-key": os.environ["COMPOSIO_API_KEY"]},
}
},
)
async with ClaudeSDKClient(options) as client:
await client.query("Send Slack message to #general: Hello!")
Auth Flow
First time using an app:
To send emails, I need Gmail access.
Authorize here: https://...
Say "connected" when done.
Connection persists after that.
Framework Support
| Framework | Install |
|---|---|
| Claude Agent SDK | pip install composio claude-agent-sdk |
| OpenAI Agents | pip install composio openai-agents |
| Vercel AI | npm install @composio/core @composio/vercel |
| LangChain | pip install composio-langchain |
| Any MCP Client | Use session.mcp.url |
Troubleshooting
- Auth required → Click link, authorize, say "connected"
- Action failed → Check permissions in target app
- Tool not found → Be specific: "Slack #general" not "send message"

content-collections
MetaThis skill provides a production-tested setup for Content Collections, a TypeScript-first tool that transforms Markdown/MDX files into type-safe data collections with Zod validation. Use it when building blogs, documentation sites, or content-heavy Vite + React applications to ensure type safety and automatic content validation. It covers everything from Vite plugin configuration and MDX compilation to deployment optimization and schema validation.
sglang
MetaSGLang is a high-performance LLM serving framework that specializes in fast, structured generation for JSON, regex, and agentic workflows using its RadixAttention prefix caching. It delivers significantly faster inference, especially for tasks with repeated prefixes, making it ideal for complex, structured outputs and multi-turn conversations. Choose SGLang over alternatives like vLLM when you need constrained decoding or are building applications with extensive prefix sharing.
evaluating-llms-harness
TestingThis Claude Skill runs the lm-evaluation-harness to benchmark LLMs across 60+ standardized academic tasks like MMLU and GSM8K. It's designed for developers to compare model quality, track training progress, or report academic results. The tool supports various backends including HuggingFace and vLLM models.
langchain
MetaLangChain is a framework for building LLM applications using agents, chains, and RAG pipelines. It supports multiple LLM providers, offers 500+ integrations, and includes features like tool calling and memory management.
