learn-codebase

Use when learning a codebase another agent (human or AI) has built, reviewing an AI-generated PR against a spec, onboarding to a single feature mid-stream, planning a change to behavior whose blast radius you do not yet know, or diagnosing suspected spec-versus-code drift. Applies whether intent docs and implementation live in the same repo or in separate planning + code repos.

Use when the user wants to be quizzed on a codebase to verify their own understanding of logical flow, domain rules, invariants, or design decisions — instead of being told. Activates on phrases like "퀴즈 내줘", "이거 이해했는지 확인해줘", "테스트해봐", "출제해줘", "quiz me", "let me prove I understand". Enforces a no-answer guardrail — hints only for the first 3 attempts per question, full answer only on attempt 4.
