# Concurrency Primitives Skill ## Overview Expert skill for implementing language-level concurrency support including threads, channels, and synchronization. ## Capabilities - Design threading API and primitives - Implement mutex and condition variables - Implement channel-based message passing - Design async/await and coroutine systems - Implement work-stealing schedulers - Handle thread-local storage - Design memory model and ordering - Implement green threads/goroutines ## Target Processes - concurrency-primitives.js - interpreter-implementation.js - bytecode-vm-implementation.js - garbage-collector-implementation.js ## Dependencies Concurrency theory, Go scheduler references ## Usage Guidelines 1. **Model Choice**: Choose between shared memory and message passing based on language goals 2. **Memory Model**: Define memory ordering semantics clearly 3. **Scheduling**: Design scheduler with fairness and efficiency in mind 4. **Integration**: Ensure GC and concurrency work together correctly 5. **Testing**: Build concurrency stress tests from the start ## Output Schema ```json { "type": "object", "properties": { "model": { "type": "string", "enum": ["shared-memory", "message-passing", "actor", "csp"] }, "primitives": { "type": "array", "items": { "type": "string" } }, "schedulerType": { "type": "string", "enum": ["os-threads", "green-threads", "work-stealing", "cooperative"] }, "generatedFiles": {...
