What problem does it solve? Designing system architecture alone risks blind spots and unchallenged assumptions. This Skill routes architecture requests through an orchestrated multi-AI workflow where external providers (Codex, Antigravity) and Claude independently evaluate the design before results are delivered. ## Core Features & Use Cases - Multi-provider architecture review: Spawns the backend-architect persona via orchestrate.sh so external models challenge and refine the design. - Enforced execution contract: Mandatory visual banner, provider availability check, and validation gates prevent skipping the orchestration step. - Broad design coverage: API design, microservices decomposition, event-driven architecture, database schema, and scalability planning. - Use Case: Ask to design a scalable notification system, and the Skill checks provider availability, runs the backend-architect persona through orchestrate.sh, verifies execution, and presents a consensus-informed architecture with attribution. ## Quick Start Ask the assistant to design the architecture for an event-driven messaging system using the octopus architecture skill.
