golang-patterns SKILL.md skillA
golang-patterns from jdanigo/hydraia is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jdanigo/hydraia/golang-patterns@git:20260702.69ee5edPins git:20260702.69ee5ed in mdr.lock. Pin the fingerprint instead.

Idiomatic Go patterns, best practices, and conventions for building robust, efficient, and maintainable Go applications.
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 Development Patterns
Idiomatic Go patterns and best practices for building robust, efficient, and maintainable applications.
## When to Activate
- Writing new Go code
- Reviewing Go code
- Refactoring existing Go code
- Designing Go packages/modules
## Core Principles
### 1. Simplicity and Clarity
Go favors simplicity over cleverness. Code should be obvious and easy to read.
```go
// Good: Clear and direct
func GetUser(id string) (*User, error) {
user, err := db.FindUser(id)
if err != nil {
return nil, fmt.Errorf("get user %s: %w", id, err)
}
return user, nil
}
// Bad: Overly clever
func GetUser(id string) (*User, error) {
return func() (*User, error) {
if u, e := db.FindUser(id); e == nil {
return u, nil
} else {
return nil, e
}
}()
}
```
### 2. Make the Zero Value Useful
Design types so their zero value is immediately usable without initialization.
```go
// Good: Zero value is useful
type Counter struct {
mu sync.Mutex
count int // zero value is 0, ready to use
}
func (c *Counter) Inc() {
c.mu.Lock()
c.count++
c.mu.Unlock()
}

How to install
mdr add jdanigo/hydraia/golang-patterns@sha256:4733a52f63d51d46The line at the top of this page pins the label git:20260702.69ee5ed, 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.
