m07-concurrency is agent-read markdown (skill) from moeru-ai/auv: CRITICAL: Use for concurrency/async. Triggers: E0277 Send Sync, cannot be sent between threads, thread, spawn, channel, mpsc, Mutex, RwLock, Atomic, async, await, Future, tokio, deadlock, race condition, 并发, 线程, 异步, 死锁.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Concurrency > **Layer 1: Language Mechanics** ## Core Question **Is this CPU-bound or I/O-bound, and what's the sharing model?** Before choosing concurrency primitives: - What's the workload type? - What data needs to be shared? - What's the thread safety requirement? --- ## Error → Design Question | Error | Don't Just Say | Ask Instead | |-------|----------------|-------------| | E0277 Send | "Add Send bound" | Should this type cross threads? | | E0277 Sync | "Wrap in Mutex" | Is shared access really needed? | | Future not Send | "Use spawn_local" | Is async the right choice? | | Deadlock | "Reorder locks" | Is the locking design correct? | --- ## Thinking Prompt Before adding concurrency: 1. **What's the workload?** - CPU-bound → threads (std::thread, rayon) - I/O-bound → async (tokio, async-std) - Mixed → hybrid approach 2. **What's the sharing model?** - No sharing → message passing (channels) - Immutable sharing → Arc<T> - Mutable sharing → Arc<Mutex<T>> or Arc<RwLock<T>> 3. **What are the Send/Sync requirements?** - Cross-thread ownership → Send - Cross-thread references → Sync - Single-thread async → spawn_local --- …

How to install
mdr add moeru-ai/auv/m07-concurrency@git:20260725.8a8e541mdr add moeru-ai/auv/m07-concurrency@sha256:c2a3e990e34c45aaPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
