/prd — Product Requirements Document Generator

When to Use

Don't use when: architecture is already defined and you need implementation (use /architect then /archon); adding a small feature to an existing app (use /marshal directly).

• User describes an app or feature to build (greenfield or feature mode)
• Before any Archon campaign for a new project or feature

Mode Detection

Before starting, determine the mode:

Greenfield mode: No existing source files, or user explicitly says "new app" / "from scratch." Produces a full PRD as described below.

Feature mode: The project already has source files (check for src/, app/, lib/, package.json with dependencies, or similar). The user describes a feature to add, not a whole app ("add auth", "add a dashboard", "add payment processing").
