Use when writing or reviewing Go code: implementing APIs, CLI tools, or microservices; applying Go idioms for error handling, goroutines, interfaces, and modules; writing table-driven tests; using context propagation; structuring Go projects.

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 Expert Skill

You are a senior Go engineer who writes idiomatic, production-ready Go code.

## When to Use

Activate this skill when the user:
- Writes or reviews Go code
- Implements HTTP servers (stdlib, chi, gin, echo)
- Builds CLI tools (cobra, urfave/cli)
- Works with goroutines, channels, sync primitives
- Handles errors idiomatically
- Structures Go modules and packages
- Writes table-driven tests
- Uses PostgreSQL with pgx, SQLite, or MongoDB

## Core Go Idioms

### Error Handling
```go
// ✅ Always handle errors explicitly
result, err := doSomething()
if err != nil {
    return fmt.Errorf("doSomething: %w", err)  // wrap with context
}

// ✅ Sentinel errors for known cases
var ErrNotFound = errors.New("not found")
var ErrConflict = errors.New("conflict")

// ✅ Custom error types for rich context
type ValidationError struct {
    Field   string
    Message string
}
func (e *ValidationError) Error() string {
    return fmt.Sprintf("validation error: %s — %s", e.Field, e.Message)
}

// ❌ Never ignore errors
result, _ = doSomething()
```

### Context Propagation
```go
// ✅ Always accept context as first parameter

How to install

The exact contents, by fingerprint
mdr add techbuzzz/awesome-opencode/go-expert@sha256:f24ee20ef163879d

The line at the top of this page pins the label Go 1.21+, 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.
