Design, implement, and review Swift APIs and Apple-platform code. Use when working on .swift files, Swift types, Foundation or AVFoundation APIs, DispatchQueue, async/await, Task, actors, MainActor, thread-affine state, or Swift-backed React Native Nitro Module implementations.
Design, implement, and review modern C++ APIs and native implementation code. Use when working on .cpp, .hpp, CMake, RAII ownership, std::variant, callbacks, async work, platform bridges, or C++-backed React Native Nitro Module implementations.
Design and review Rust trait APIs, generic bounds, dispatch models, and conversion contracts for clear public interfaces. Use when designing, refactoring, or reviewing traits, generics, trait objects, associated types, impl Trait, From/TryFrom, AsRef, Borrow, or crate APIs.
Design, explain or redesign a system at the level of services, data stores, APIs and scale, through the system design delivery framework. Use when designing a new backend or distributed system, explaining or documenting an existing one, redesigning or scaling one, or choosing a database, cache, queue or protocol.
Review existing Rust code for idiom, API design, error handling, safety, and maintainability, and produce a prioritized report where every finding cites the rule it breaks and gives a concrete fix. Use this whenever the user asks to review, audit, critique, grade, or "check" Rust code, a crate, a module, a .rs file, a diff, or a pull request, or asks what is wrong with their Rust or how to make it more idiomatic, even if they don't say "review". Pairs with the rust-best-practices skill, which covers writing new code.
Plans the stack, database schema and API for an app clone, from the recon map replica-recon wrote. Picks boring, managed tech, turns the inferred data model into real SQL with indexes and access rules, lists every route by flow, and orders the build as a thin vertical slice first. Use when the user says "plan the clone", "what stack should I use", "design the database", "write the schema", "plan the API", "architecture for my version of X", or after /replica-recon finishes.
Primitive-first product design. Use when shaping a new product, app, SDK, API, or tool surface, deciding what to build and what to leave to the caller, writing a spec or PRD, or judging whether an idea is worth building.
