/architect — Implementation Architecture from PRD

When to Use

Don't use when: you already have an architecture and want to implement it (use /marshal or /archon); you need a PRD first (use /prd before /architect).

• After /prd produces an approved PRD (greenfield or feature mode)
• When the user has a clear direction + existing codebase (no PRD needed)
• When /do routes a build request
• When the user has a spec and wants a build plan

Inputs

One of:

1. A PRD file path (from /prd) — preferred, contains structured requirements
2. A user-provided spec or description + an existing codebase — sufficient
3. Neither — suggest /prd first, but don't hard-gate. If the user has a clear direction ("add auth to my app"), that + the existing code IS the input.
