go-best-practices from aiskillstore/marketplace is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add aiskillstore/marketplace/go-best-practices@git:20260705.e9e4712Pins git:20260705.e9e4712 in mdr.lock. Pin the fingerprint instead.

Use when reading or writing Go files (.go, go.mod).
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 Best Practices
Follows type-first, functional, and error handling patterns from CLAUDE.md. This skill covers language-specific idioms only.
## Make Illegal States Unrepresentable
Use Go's type system to prevent invalid states at compile time.
**Custom types for domain primitives:**
```go
// Distinct types prevent mixing up IDs
type UserID string
type OrderID string
func GetUser(id UserID) (*User, error) {
// Compiler prevents passing OrderID here
}
// Methods attach behavior to the type
func (id UserID) String() string {
return string(id)
}
```
**Interfaces for behavior contracts:**
```go
// Define what you need, not what you have
type UserRepository interface {
GetByID(ctx context.Context, id UserID) (*User, error)
Save(ctx context.Context, user *User) error
}
// Accept interfaces, return structs
func ProcessInput(r io.Reader) ([]byte, error) {
return io.ReadAll(r)
}
```
**Enums with iota and exhaustive switch:**
```go
type Status int
const (
StatusActive Status = iota + 1
StatusInactive
StatusPending
)
func ProcessStatus(s Status) (string, error) {
switch s {
case StatusActive:
return "processing", nil

How to install
mdr add aiskillstore/marketplace/go-best-practices@sha256:884ef41b4cdd0172The line at the top of this page pins the label git:20260705.e9e4712, 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.
