go-concurrency-patterns is agent-read markdown (skill) from rudycity/superagent: Master Go concurrency with goroutines, channels, sync primitives, and context. Use when building concurrent Go applications, implementing worker pools, or debugging race conditions..
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.

# Go Concurrency Patterns
Production patterns for Go concurrency including goroutines, channels, synchronization primitives, and context management.
## When to Use This Skill
- Building concurrent Go applications
- Implementing worker pools and pipelines
- Managing goroutine lifecycles
- Using channels for communication
- Debugging race conditions
- Implementing graceful shutdown
## Core Concepts
### 1. Go Concurrency Primitives
| Primitive | Purpose |
| ----------------- | -------------------------------- |
| `goroutine` | Lightweight concurrent execution |
| `channel` | Communication between goroutines |
| `select` | Multiplex channel operations |
| `sync.Mutex` | Mutual exclusion |
| `sync.WaitGroup` | Wait for goroutines to complete |
| `context.Context` | Cancellation and deadlines |
### 2. Go Concurrency Mantra
```
Don't communicate by sharing memory;
share memory by communicating.
```
## Quick Start
```go
package main
import (
"context"
"fmt"
"sync"
"time"
)
func main() {
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
…
Pin 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.
