go-concurrency SKILL.md skillA
go-concurrency from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/go-concurrency@git:20261029.0a51226Pins git:20261029.0a51226 in mdr.lock. Pin the fingerprint instead.

Use when designing or debugging Go goroutines, channels, select, bounded worker pools, pipelines, fan-in/fan-out, semaphores, rate limits, context cancellation, sync locks/atomics, goroutine leaks, data races, or container GOMAXPROCS limits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Go Concurrency ## Route the work | Task or symptom | Start here | |---|---| | Blocked send, closed/nil channel, cancellation or missing result | [Ownership and channels](references/ownership-and-channels.md) | | Growing backlog, worker pool, pipeline, semaphore, rate limiter or pub/sub | [Bounded work](references/bounded-work.md) | | Shared map/counter, lock copying, initialization or reusable buffers | [Synchronization](references/synchronization.md) | | Race, deadlock, timer/synctest upgrade, container CPU/memory limits | [Runtime and diagnostics](references/runtime-and-diagnostics.md) | Read the relevant reference before changing its mechanism. Sources and optional siblings are not dependencies. ## Workflow 1. **Start sequential.** Identify blocking I/O versus CPU work and the invariant requiring concurrency. CPU count alone cannot size I/O workers. 2. **Name owners.** Who starts/stops/joins each goroutine, closes each channel and mutates each object? Returning from `main` terminates goroutines without joining. 3. **Bound the path.** Limit active operations, waiting jobs, payload bytes, retained …

How to install
mdr add lu1sdv/skillsmd/go-concurrency@sha256:79888576293f090cThe line at the top of this page pins the label git:20261029.0a51226, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
