go-idioms SKILL.md skillA
go-idioms from tanq16/claudex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Modern Go 1.27+ idioms and dependency selection, applied to every Go file written or reviewed. Use when writing or refactoring any Go code, when reading or writing JSON, when choosing between a standard-library helper and a hand-rolled loop, or when adding, auditing, or upgrading a dependency in go.mod. Triggers on interface{}, wg.Add, errors.As, atomic.LoadInt32, manual index loops, sync.Once, time.Now().Sub, encoding/json, json.MarshalIndent, json.NewDecoder, google/uuid, and on any 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 Idioms
**The Go 1.27+ baseline every file in these projects is written to, and how a dependency earns its place in `go.mod`.**
The `go` directive reads `go 1.27` or newer on every project. There is no version detection and no fallback path, so a current idiom is always available and an outdated one is always a choice. `go test` runs the `stdversion` vet check by default, so a symbol newer than the directive is reported rather than discovered by a user on an older toolchain.
`go fix` applies part of this file mechanically: `atomictypes` moves `sync/atomic` calls onto the typed atomics, and `waitgroupgo` rewrites an `Add`, `go`, `Done` trio into `wg.Go`.
## Types and Built-ins
`any` replaces `interface{}`, because the two are identical to the compiler and only one of them reads as deliberate.
`min` and `max` replace hand-rolled comparisons: `max(a, b)`, `min(start+size-1, end)`.
`clear` empties a map (`clear(m)`) or zeroes a slice's elements (`clear(s)`), which frees the caller from a loop whose only job is bookkeeping.
## slices
Prefer these over manual loops, since each one states the intent that a loop only implies.
- `slices.Contains(items, x)` for membership.

How to install
mdr add tanq16/claudex/go-idioms@sha256:d9ea701e96de4ef2The line at the top of this page pins the label git:20260827.716177c, 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.
