go-concurrency SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
go-concurrency from fusengine/claude-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/claude-plugins/go-concurrency@git:20260927.43a351cPins git:20260927.43a351c in mdr.lock. Pin the fingerprint instead.

Use when writing or reviewing Go concurrency — goroutines, channels, errgroup, context cancellation, or goroutine leaks. Not for sequential idioms (go-core-idioms).
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
<objective> Covers Go concurrency for Go 1.27: goroutines and channels, golang.org/x/sync/errgroup, context propagation and cancellation, sync.WaitGroup vs channels, the -race detector, and diagnosing goroutine leaks (including the goroutineleak profile, GA in 1.27). Does not cover sequential error handling, slog, generics, or interface style (see go-core-idioms), non-Go languages, or framework-specific code. </objective> # Go Concurrency Goroutines, channels, `context`, and `errgroup` for Go 1.27 — plus the number-one documented pitfall: **leaking goroutines on an unbuffered channel + early return.** ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Map existing goroutine/channel/context usage 2. **fuse-ai-pilot:research-expert** - Verify errgroup/context docs via Context7/Exa 3. **mcp__context7__query-docs** - Confirm `golang.org/x/sync/errgroup` signatures After implementation, run **fuse-ai-pilot:sniper** for validation, and run tests with `go test -race ./...`. --- ## Overview | Feature | Description | |---------|-------------| …

How to install
mdr add fusengine/claude-plugins/go-concurrency@sha256:112d65dedc345a09The line at the top of this page pins the label git:20260927.43a351c, 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.
