What problem does it solve? Starting a new project without structured documentation leads to scope creep, inconsistent architecture, and quality drift across AI-assisted development sessions. This Skill generates four foundation documents that keep every session aligned with the project's goals and constraints. ## Core Features & Use Cases - PRD Generation: Creates a Product Requirements Document with an explicit out-of-scope list, success metrics, and constraints to guard against scope creep. - Architecture & AI Rules: Produces an architecture document covering tech stack, data model, and service boundaries, plus a CLAUDE.md with non-negotiable coding rules. - Phased Planning: Generates a step-by-step Phase 1 plan where each step is independently verifiable and ends with a commit. - Use Case: When kicking off a new SaaS app, invoke the skill to answer four discovery questions, then receive an approved PRD, architecture doc, CLAUDE.md, and an executable first-phase plan. ## Quick Start Ask the AI to scaffold a new project by describing what you are building, who it is for, your tech stack preference, and any hard constraints.
