Agent
Architecture, planning, and codebase-onboarding specialist. Use to design an approach, break a task into a plan other agents can execute, or map an unfamiliar codebase before work starts.
Agent
Full-stack engineer for backend and frontend implementation. APIs, databases, authentication, UI components, styling. Delegate concrete implementation work here once the approach is decided.
Agent
Refutation-based code reviewer. Actively tries to disprove that a change works, rather than confirming it looks fine. Use after implementation work to get an honest defect list before merging.
Agent
Testing specialist. Writes and runs tests that verify real behavior. Use after implementation work to establish honest, risk-based coverage rather than a coverage-percentage target.
