Architecture Skill

Provides architectural guidance for system design decisions, including:

• ADR (Architecture Decision Records): Structured format for recording design decisions with context, options, and rationale
• System Design Checklist: Scalability, reliability, observability, security considerations
• Architecture Patterns: Microservices, event-driven, layered, hexagonal
• API Design: RESTful conventions, versioning, pagination, error handling

When Loaded

This skill is automatically injected when working with:

• /cc-best:lead — Technical design phase
• architect agent — System architecture decisions
• planner agent — Task breakdown and complexity analysis

Key Principles

1. Simplicity first — Choose the simplest architecture that meets requirements
2. Document decisions — Every significant choice gets an ADR
3. Separation of concerns — Clear boundaries between components
4. Design for failure — Graceful degradation and circuit breakers
