name: planning-design description: Design technical architecture, select technology stack, and define implementation strategy from specifications and constitution constraints. allowed-tools: Read, Bash, Grep, Glob, WebFetch, WebSearch, Agent, AskUserQuestion graph: domains: [domain:software-engineering] skillAreas: [skill-area:agentic-loops, skill-area:orchestration-loop] workflows: [workflow:feature-development] topics: [topic:developer-experience] roles: [role:tech-lead, role:backend-engineer]

• When evaluating technology stack options for a feature
• When designing system architecture for new components
• When assessing implementation risks and defining mitigations

Key Principle

Architecture decisions must be traceable to specification requirements. Technology choices must comply with constitution constraints. Trade-offs must be documented for every significant decision.

Process

1. Assess technology stack - Evaluate options against constitution requirements
2. Design architecture - Components, interfaces, data model, integration points
3. Define strategy - Phases, milestones, testing strategy, deployment approach
4. Assess risks - Identify risks and define mitigations
5. Human review - Approve architecture and strategy before task breakdown
