reconstruct

Use when the user wants to rebuild, recreate, clone, or reverse-engineer an existing repository from scratch, or turn a codebase into specs/PRDs — e.g. "rebuild this project", "reverse engineer this repo", "generate a PRD/spec from this code", "recreate this app". ALSO use for greenfield asks — "build a new project from scratch", "turn my idea into PRDs / a build plan", "design a new app", "greenfield" — where there is no code yet and the facts are elicited through an interview. Works on any stack (JS/TS, Python, Ruby, Go, PHP, Java, mobile…). ALSO brainstorm product directions before building — "brainstorm ideas", "explore concepts", "compare approaches", "what should we build" — a divergent phase that generates several concepts and converges on one. Keywords: reconstruct, rebuild, clone, reverse engineer, from scratch, greenfield, build plan, new project, idea to PRD, brainstorm, ideation, explore concepts, compare approaches.
