Production-ready spec driven development setup for AI coding agents in any repo with one command. Pre-configured with 11 agents, 22 skills, 18 rules, 25 commands & MCP integrations for Cursor, GitHub Copilot, Claude Code, Windsurf, Amp, Codex, Gemini CLI, Cline & OpenCode.
Crack the egg. Hatch better agents.
hatch3r is an open-source CLI and Cursor plugin that installs a battle-tested, tool-agnostic agentic coding setup into any repository. One command gives you up to 16 agents, 26 skills, 26 rules, 34 commands, and MCP integrations -- optimized for your coding tool of choice. Selective init installs only what you need based on your project type and team size.
Requires Node.js 22+.
npx hatch3r init
That's it. hatch3r detects your repo, asks about your project context (greenfield/brownfield, solo/team), lets you choose a content profile (minimal/standard/full/custom), and generates everything. The platform (GitHub, Azure DevOps, or GitLab) is auto-detected from your git remote. Run into issues? See Troubleshooting.
