Testing practices for iOS 26 / Swift 6.2 clinic modular MVVM-C applications. Covers unit/UI/snapshot testing, protocol-based mocks, async actor isolation, and dependency-injected test architecture aligned with Domain protocols, App-target composition, and Data-owned I/O boundaries. Use when writing, reviewing, or refactoring tests for ios-* and swift-* clinic modules.
This skill should be used when the user asks to "add background processing", "cache this data", "run this async", "handle concurrent requests", "manage state across requests", "process jobs from a queue", "this GenServer is slow", or mentions GenServer, Supervisor, Agent, Task, Registry, DynamicSupervisor, handle_call, handle_cast, supervision trees, fault tolerance, "let it crash", or choosing between Broadway and Oban.
Apply before writing logic: choosing core types and data structures, sequencing scaffold-vs-feature work, asking what concurrent actors share. Get the data structures right so downstream code becomes obvious.
Generate a complete Model Context Protocol server project in Swift using the official MCP Swift SDK package.
OTP patterns for Elixir — GenServer, Agent, Task, ETS, supervision trees, Registry, and process design. Use when designing concurrent systems, stateful processes, or deciding when (and when NOT) to use processes.
Use when working on or reviewing session execution, command handling, shell state, FIFO-based streaming, or stdout/stderr separation. Relevant for session.ts, command handlers, exec/execStream, or anything involving shell process management. (project)
Configure transaction isolation levels to prevent race conditions and handle concurrent access. Use when dealing with concurrent updates, financial operations, inventory management, or when users mention race conditions, dirty reads, phantom reads, or concurrent modifications.
