golang SKILL.md skillA
golang from xobotyi/cc-foundry is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xobotyi/cc-foundry/golang@git:20261026.6f73fdbPins git:20261026.6f73fdb in mdr.lock. Pin the fingerprint instead.

Write and review Go: idioms, error handling, concurrency, testing, project structure, the toolchain, and the language version a module's `go` directive permits.
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
Simplicity is the highest Go virtue. Three biases decide most calls: - **Resist abstraction until the cost of not abstracting is proven.** An interface, a type parameter, or a layer added in anticipation of a second caller is a defect. - **Reach for the standard library first.** A dependency earns its place by doing what the standard library does not. - **The `go` directive decides what may be written**, not the installed toolchain. ## Language Version The `go` directive in `go.mod` sets the language version a module may use. Read it before writing code and never reach for a feature above it. The `stdversion` analyzer reports a standard-library symbol newer than the directive: Go 1.27 and later fail `go test` on it, earlier toolchains report it under `go vet`. Floor version per feature. Anything older than 1.21 is available in every supported module. - **1.21** — `min`, `max`, `clear` builtins; `slices`, `maps`, `cmp`, `log/slog`; `context.WithoutCancel`; `errors.ErrUnsupported`; `sync.OnceValue` - **1.22** — per-iteration loop variables; `for range int`; `math/rand/v2`; method and wildcard patterns in `net/http.ServeMux` …

How to install
mdr add xobotyi/cc-foundry/golang@sha256:81b6a922d2764977The line at the top of this page pins the label git:20261026.6f73fdb, 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.
