Skills are downloadable instruction files that teach an AI how to do something specific. MCP servers connect external services like GitHub and Stripe to your AI coding tool. Rules are config files that encode your team's conventions and coding standards. Agents combine all three into automated workflows you run with a single command.

Frequently asked questions

A developer directory for AI coding tools. We publish tool profiles, head-to-head comparisons, installable skills, agent build guides, MCP server configs, and structured learning courses. Everything is free to read and use.
Every major AI coding tool. Claude Code, Cursor, GitHub Copilot, Windsurf, Codex, Devin, Gemini CLI, and more. Each tool has a profile page with pricing, features, and links to its compatible skills, rules, and agents.
An automated workflow assembled from components. A code review agent combines a code review skill, a CLAUDE.md rule file, a GitHub MCP server connection, and Claude Code as the platform. The agent page walks you through the full build, step by step.
Codegen was acquired by ClickUp in 2025. The directory is editorially independent and covers all tools equally. ClickUp provides the workflow layer where agent output like PRs, docs, and test reports gets tracked and managed.
