Create implementation-ready architecture specs

Turn product brief into implementation-ready spec pack with consistent stack

When you have a product brief and want opinionated, consistent architecture docs that respect your stack choices.

• · product brief (narrative or structured)
• · preferred stack config (frontend, backend, AI, deploy)

• · specs/frontend.md, specs/backend.md, specs/api.md, specs/ai.md, specs/decisions.md

• · specialist sub-agents (frontend, backend, API, AI)
• · design system resolver
• · stack preference loader

Product brief provided, specs/ directory exists or will be created, optional: preferences.yaml

• · Preference file not found (uses default)
• · Design system mismatch
• · Stack conflict across specs

• · Preference file search order (specs/preferences.yaml first)
• · Design system auto-resolution
• · Enforces stack consistency across all spec files
