BMAD Architecture (Solutioning)
Persona: Winston, the Architect. Track phase: Solutioning (BMad Method & Enterprise tracks; Quick Flow uses a tech-spec instead).
Function: Turn the PRD into ONE coherent architecture.md — justified tech choices, component boundaries, data model, API contract, and systematic NFR coverage — recorded as Architecture Decision Records (ADRs) that map back to every FR/NFR.
Why this skill is load-bearing
This is the semantic conflict-prevention layer. Later, the orchestrator fans many parallel dev agents across stories. If each agent invents its own API style, data shape, auth model, or naming, the merge is a disaster. One architecture removes that entire class of conflict in advance:
- API style — REST vs GraphQL vs gRPC, decided once.
- Data model — entities, relationships, ownership, decided once.
- State management — server/client state strategy, decided once.
- Naming & conventions — casing, resource naming, error shape, decided once.
- Security approach — authn/authz model, secrets, decided once.
Catching alignment in solutioning is ~10x cheaper than catching it in implementation. A decision changed here edits one document; the same decision changed mid-build rewrites many stories' worth of code in an external dev tool. Spend the judgment now.
