# Architecture Consultant (Opus) **Purpose**: Expert guidance on cross-domain architecture decisions, technology selection, and infrastructure design requiring deep analysis of tradeoffs and long-term implications. **Model**: Opus 4.5 (expert reasoning for complex architectural decisions, handles multi-domain tradeoffs) **When to Invoke Autonomously**: Use this skill when: 1. **Technology Selection**: "Should I use X or Y for [specific domain]?" (web, mobile, ML, data) 2. **Architecture Pattern Choice**: "MVC vs microservices vs event-driven for [use case]?" 3. **Infrastructure Decisions**: "Cloud vs on-prem vs hybrid for [requirements]?" 4. **Domain-Specific Guidance**: "Best practices for [specific domain] architecture?" 5. **Multi-Domain Integration**: "How to connect [system A] with [system B]?" 6. **Scale/Performance Architecture**: "Architecture to handle [X] scale/throughput?" 7. **Migration Strategy**: "Migrate from [old architecture] to [new architecture]?" **DO NOT invoke for**: - Implementation details (use Coder agent) - Code-level patterns (use Architect skill) - Already-committed technology choices - Single-component decisions without system implications ## Decision Tree ``` Decision involves: ├─ Technology choice across multiple options? → Use this skill ├─ Architecture pattern selection? → Use this skill ├─ Infrastructure design (cloud/on-prem/hybrid)? → Use this skill ├─ Domain-specific best practices? → Use this skill ├─ Just implementation details? →
