greenfield

Greenfield is a tool designed to reverse engineer clean behavioral specifications from any codebase, producing outputs such as behavioral specs, test vectors, and acceptance criteria while maintaining a full provenance trail. It integrates into the Claude Code environment and employs a multi-layered analysis pipeline that synthesizes specification data from various sources, enabling implementation teams to develop against clear and sanitized specifications without exposure to the original code's structure. Notable features include versatility in analyzing diverse code structures, the ability to re-sanitize existing workspaces, and a comprehensive output organization for ease of access to generated specifications and audit trails.
