Project Blueprint · drewggm bundle Acts as software architect to define a software system from scratch BEFORE writing code. Turns a raw idea into a validated, code-ready blueprint — refining the idea, writing the spec/PRD, choosing the architecture, setting the security, quality and testing baseline, and writing the plan and agent handoff files into the repo. Use when starting a new project, feature, or system, when the user says "design/plan/define/architect X", "empezar un proyecto", "definir el sistema antes de codear", or wants a PRD, architecture, technical plan, ADR, or threat model.
