golang-patterns SKILL.md skillA
golang-patterns from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add affaan-m/ecc/golang-patterns@git:20260330.866d9ebPins git:20260330.866d9eb in mdr.lock. Pin the fingerprint instead.

Go-specific design patterns and best practices including functional options, small interfaces, dependency injection, concurrency patterns, error handling, and package organization. Use when working with Go code to apply idiomatic Go patterns.
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 Patterns
> This skill provides comprehensive Go patterns extending common design principles with Go-specific idioms.
## Functional Options
Use the functional options pattern for flexible constructor configuration:
```go
type Option func(*Server)
func WithPort(port int) Option {
return func(s *Server) { s.port = port }
}
func NewServer(opts ...Option) *Server {
s := &Server{port: 8080}
for _, opt := range opts {
opt(s)
}
return s
}
```
**Benefits:**
- Backward compatible API evolution
- Optional parameters with defaults
- Self-documenting configuration
## Small Interfaces
Define interfaces where they are used, not where they are implemented.
**Principle:** Accept interfaces, return structs
```go
// Good: Small, focused interface defined at point of use
type UserStore interface {
GetUser(id string) (*User, error)
}
func ProcessUser(store UserStore, id string) error {
user, err := store.GetUser(id)
// ...
}
```
**Benefits:**
- Easier testing and mocking
- Loose coupling
- Clear dependencies
## Dependency Injection
Use constructor functions to inject dependencies:
```go

How to install
mdr add affaan-m/ecc/golang-patterns@sha256:835e7727ad680662The line at the top of this page pins the label git:20260330.866d9eb, 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.
