Unified Authentication and Authorization: Standardizing AI Token Issuance and Verification Logic
In AI programming, there is one category of code that easily “grows and grows messier”: if user.role != "admin": raise HTTPException(status_code=403) Switch to another endpoint, and the AI writes: if "user:delete" not in user.permissions: raise ForbiddenError() Yet another endpoint: if current_user.id != owner_id and not current_user.is_admin: raise HTTPException(status_code=403) Each snippet looks defensible on its own. But once dozens of variations of these ifs appear across the project, the permission system has effectively gone out of control. The mature solution is not “make the AI write its if-statements more carefully”, but to establish a unified: Authentication + permission model + permission enforcement mechanism The most common permission model here is RBAC (Role-Based Access Control). ...
