Create or migrate a protected Sim resource operation in the shared Principal and application-use-case architecture across internal APIs, public or versioned APIs, Copilot, and other trusted tool adapters. Use when adding a protected endpoint, tool command, or CRUD method; removing route- or tool-local authorization and business logic; consolidating resource reads or writes behind semantic operation policies; or adding another surface to an existing application operation while preserving contracts, identity, errors, rate limits, audit, analytics, and compatibility behavior. Treat v1, uploads, streams, large bodies, bulk recursion, and polymorphic tools as explicitly scoped special cases.
