hatch3r
An open-source CLI and editor plugin that installs a full tool-agnostic agentic coding setup — agents, skills, rules, commands, hooks and MCP integrations — into any repository for Claude Code, Cursor or GitHub Copilot.
hatch3r generates a working agentic-coding setup for a repository in one command, detecting whether the project is greenfield or brownfield and solo or team-sized, then walking through platform, content-profile and tool choices before writing everything needed for Claude Code, Cursor or GitHub Copilot. As of version 1.9.0 it dropped support for twelve other adapters, reads its canonical content from the bundled npm package rather than materializing it into the user's repository, and moved its manifest to a project-local file.
A selective-init mode installs only what a given project type and team size need, existing rules from Cursor, Copilot, Windsurf or a root AGENTS.md can be imported and land under an overrides directory with per-file conflict reporting, and each release is audited across 24 governance domains, with live counts published in the project's own inventory file.
