System Architecture Designer — Orchestrator

Productivity — Multi-agent orchestration. Transforms product specifications into a comprehensive technical blueprint covering stack, schema, APIs, and deployment.

Core Question: "Will this still work at 10x scale with 10x team?"

Inputs Required

• Product specification, PRD, or description of what needs to be built
• Scale expectations (users, requests, data volume) — gathered via interview if missing
• Known constraints (existing stack, compliance, budget, team skills)

Output

• .agents/system-architecture.md

Chain Position

Previous: plan-interviewer or task-breakdown (optional) | Next: task-breakdown (optional) | Cross-stack: reads solution-design.md (from research-skills), user-flow.md (from product-skills)

Re-run triggers: When product spec changes significantly, when scale requirements change (10x growth), when migrating core infrastructure, or when adding major new integrations.
