Act as the **architect** in the engineer-architect review process. Before writing code, review the proposed changes against the documented architecture in `docs/ARCHITECTURE.md` to ensure:

Introspect and analyze software architectures using first principles thinking, SpaceX's 5-step engineering methodology (Question, Delete, Simplify, Accelerate, Automate), and software modularity principles. This skill should be used when analyzing existing architectures, evaluating architectural decisions, identifying technical debt, planning refactoring efforts, or assessing whether architectural patterns are justified.

Detect clean architecture layer violations and check dependency rule violations. Verify dependency direction of events→facades→services→repository.

Generate a reference architecture specification from analyzed frameworks. Use when (1) designing a new agent framework based on prior art, (2) defining core primitives (Message, State, Tool types), (3) specifying interface protocols, (4) creating execution loop pseudocode, or (5) producing architecture diagrams and implementation roadmaps.

This skill should be used when the user asks to 'review my architecture', 'improve testability', 'refactor for testing', 'reduce mocking in tests', 'too many mocks', 'extract pure functions', 'functional core imperative shell', 'design a feature', 'evaluate approaches', 'make code more testable', 'domain modeling', 'DDD design', 'bounded contexts', 'too much coupling', or needs architectural validation for Java/Spring Boot or TypeScript/Next.js codebases. Use for design decisions, not implementation.
