# 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 (
