principle-concurrency

What problem does it solve?

This Skill helps you prevent subtle concurrency failures by teaching principled approaches to races, deadlocks, cancellation, and backpressure before they become production incidents.

Core Features & Use Cases

• Failure mode guidance: Recognize and fix race conditions, deadlocks, livelocks, starvation, lost wakeups, and ABA/CAS pitfalls.
• Structured concurrency rules: Ensure child lifetimes nest under parent lifetimes with clear error propagation and no orphan work.
• Practical primitive selection: Choose between mutex, channel, actor, semaphore, and atomics/CAS based on ownership, performance, and correctness.

Quick Start

Ask the AI: “How should I structure cancellation propagation and backpressure in my concurrent worker pipeline, and which synchronization primitive should I use to avoid races and deadlocks?”
