Auth Flow Planner

What this skill does

This skill designs a complete authentication and authorization flow for any application. It covers the full lifecycle: registration, login, session management, token refresh, password reset, role-based access control, and all the edge cases (expired tokens, concurrent sessions, brute force protection). The output is a detailed design document with flow diagrams, endpoint definitions, data models, and security considerations — ready to hand off to engineering.

Use this when starting a new application, when auditing an existing auth system, or when extending your auth with new features (OAuth, MFA, roles).
