Quickstart: Connect Claude to 500+ Apps

The connect-apps plugin lets Claude perform real actions - send emails, create issues, post to Slack. It handles auth and connects to 500+ apps using Composio under the hood.

1. Install the Plugin

claude --plugin-dir ./connect-apps-plugin

2. Run Setup

/connect-apps:setup

Paste your API key when asked. (Get a free key at dashboard.composio.dev)

3. Restart & Try It

exit
claude

What Are Claude Skills?

Claude Skills are reusable instruction packages that teach an AI agent how to handle a specific class of tasks. Each skill is a folder containing a SKILL.md file with YAML frontmatter (name, description) and Markdown instructions, optionally bundled with scripts, references, and assets. Anthropic introduced the format in October 2025 and released it as an open standard in December 2025; it's now supported by Claude Code, Claude.ai, the Claude API, OpenAI Codex, Cursor, Gemini CLI, Antigravity, and Windsurf.

Skills load progressively. At session start, the agent sees only each skill's name and description — roughly 100 tokens per skill. The full SKILL.md body (typically under 5,000 tokens) loads only when the agent decides the skill is relevant to the current task. Auxiliary files in scripts/ and references/ load on demand. This is what lets a single agent host hundreds of skills without bloating its context window.

Skills are not MCP servers and not tools. MCP defines how an agent connects to external systems — auth, transport, tool discovery. Tools are the individual functions an agent invokes. Skills define the workflow — what to do, in what order, with what guardrails — once the agent has the connections and tools it needs. In production, all three layers run together: MCP for access, tools for actions, skills for behavior.

Development & Code Tools

• artifacts-builder - Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui).
• aws-skills - AWS development with CDK best practices, cost optimization MCP servers, and serverless/event-driven architecture patterns.
• building-blog - Adds an SEO-first, i18n-ready blog to a Next.js + Sanity site via a 40-question intake, a one-page plan, and a 20-section spec. Includes a generator for AI hero images via Gemini 3 Pro Image (Nano Banana Pro). By @BuildShipGrowRepeat
• Changelog Generator - Automatically creates user-facing changelogs from git commits by analyzing history and transforming technical commits into customer-friendly release notes.
• Chrome Relay - Drives the user's already-open Chrome session — cookies, SSO, extensions, localhost — through a local CLI bridge. Real-Chrome counterpart to Playwright Browser Automation; install via npx skills add chrome-relay + a Chrome Web Store extension. No remote relay, no Playwright fixtures, no MCP server needed.
• Claude Code Terminal Title - Gives each Claud-Code terminal window a dynamic title that describes the work being done so you don't lose track of what window is doing what.
• Connect - Connect Claude to any app. Send emails, create issues, post messages, update databases - take real actions across Gmail, Slack, GitHub, Notion, and 1000+ services.
• D3.js Visualization - Teaches Claude to produce D3 charts and interactive data visualizations. By @chrisvoncsefalvay
• FFUF Web Fuzzing - Integrates the ffuf web fuzzer so Claude can run fuzzing tasks and analyze results for vulnerabilities.
