Development

Employ the Hexagonal (Ports & Adapters) pattern to decouple domain logic from infrastructure, maximizing flexibility and testability. Use when designing systems that need strong separation between business logic and external dependencies.

Employ the "Functional Core, Imperative Shell" pattern to isolate deterministic business logic from side-effecting code for superior testability. Use when designing systems where pure functions and immutable data improve testability.

Structure systems around asynchronous, event-based communication to decouple producers and consumers for improved scalability and resilience. Use when building loosely coupled systems with asynchronous message-based communication.

Apply Command Query Responsibility Segregation (CQRS) and Event Sourcing (ES) for collaboration-heavy domains that require strong auditability and independent scaling of reads and writes. Use when designing systems requiring audit trails, event replay, or separate read/write scaling.

Model system responsibilities across clients, servers, and optional peer-to-peer nodes. Use when designing systems with clear client-server communication needs.

Evaluate Claude skill quality through auditing. Use when reviewing or auditing skills.

Guide creating Claude Code skills with TDD and persuasion principles. Use for new skill development.

Build composable skill modules with hub-and-spoke loading. Use when token budget is tight.

Guide creating Claude Code hooks with security-first design. Use for validation and enforcement.

Analyze skill complexity and get modularization recommendations

Use when designing or architecting Rust applications, creating comprehensive project documentation, planning async/await patterns, defining domain models with ownership strategies, structuring multi-crate workspaces, or preparing handoff documentation for Director/Implementor AI collaboration

Safe git operations including commits, branches, merges, worktrees, and conflict resolution. Use when user wants to commit and push changes, manage branches, resolve conflicts, or create isolated workspaces. Activates when user says "commit", "push", "merge", "branch", "pull", "rebase", "worktree", "conflict", or similar git workflow requests.
