go-style SKILL.md skillA

go-style from bitwise-media-group/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Modern Go code style for stdlib-first programs — error wrapping with %w, sentinel errors, structured logging with log/slog, context threading, consumer-defined interfaces, nil-safe constructors, net/http servers with method-pattern routing, flag/env configuration for services, and cobra commands with viper configuration for CLI tools. Use when writing, reviewing, or refactoring any Go code (.go files, packages, services, CLIs): handling or wrapping errors in Go, adding structured logging to a…

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 style conventions

Stdlib-first conventions for modern Go (1.22+). Apply them to new code and match them when editing
existing code; reach for a third-party dependency only when the standard library genuinely cannot
do the job. For the rationale behind each rule and extended examples, see
[reference.md](reference.md).

## 1. Wrap errors with `%w` and the failing operation, exactly once

Name the operation lowercase, no "failed to", no trailing punctuation. Wrap where context is
added; pass through errors that are already contextual:

```go
if err := v.BindPFlags(fs); err != nil {
	return nil, fmt.Errorf("bind flags: %w", err)
}
if err := cfg.Validate(); err != nil {
	return nil, err // Validate's message already says what failed — don't double-wrap
}
```

`%w` keeps the chain inspectable with `errors.Is`/`errors.As`; a `%v` wrap severs it.

## 2. Sentinel errors for conditions callers branch on

Declare package-level sentinels with `errors.New`; expose structured failures as error types.
Callers match with `errors.Is` (sentinels) or `errors.As` (types) — never by comparing message
strings.

```go
var ErrUnknownClient = errors.New("unknown client")
```
…

How to install

The exact contents, by fingerprint
mdr add bitwise-media-group/skills/go-style@sha256:535ef253ce1402aa

The line at the top of this page pins the label git:20260701.20789e5, 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.
