# 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
