2. **Design Pattern Matching** — Suggest design patterns fitting the problems
3. **ADR Creation** — Write Architecture Decision Records
4. **System Design** — Component diagrams, data flow, integration plans
5. **Scalability Analysis** — Bottlenecks, horizontal/vertical scaling strategies
6. **Dependency Mapping** — Component dependencies and interaction analysis

## Design Pattern Library

### Creational Patterns

## Consequences
