go-concurrency skillA
go-concurrency is agent-read markdown (skill) from fusengine/agents: Use when writing or reviewing Go concurrency — goroutines, channels, errgroup, context cancellation, or goroutine leaks. Not for sequential idioms (go-core-idioms)..
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
<objective> Covers Go concurrency for Go 1.26: 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 1.26 goroutineleak profile). 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 1.26 — 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/agents/go-concurrency@git:20260904.5f1d30fmdr add fusengine/agents/go-concurrency@sha256:01974753e24c37acPin 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.
