go SKILL.md skillA
go from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when writing, reviewing, testing, or shipping Go code and HTTP services: idioms, `%w` error wrapping, goroutine/context/errgroup concurrency, net/http 1.22 routing, log/slog, project layout, table-driven tests, Go hardening. NOT language-agnostic threat modeling (that is `secure-coding`), NOT Dockerfile/CI shipping (that is `deployment`).
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
# Idiomatic Go services
Targets **Go 1.22+** (Go 1.26 is the current stable release): enhanced `net/http` routing
(`mux.HandleFunc("GET /users/{id}", h)` + `r.PathValue`), `log/slog` structured
logging, and fixed loop-variable semantics (no more `tt := tt`).
> **⚠️ SDD new-feature gate — read this first.** If this skill fired on a **new, non-trivial feature or behaviour change** and there is **no approved spec + plan** under `02-DOCS/wiki/sdd/`, STOP — do **not** write feature code yet. Hand off to `../specify/SKILL.md` first: it runs brainstorm → spec → plan → tasks before any code, then routes back here once the plan is approved. Build here directly only for a genuinely one-line / low-risk change. Method: `../sdd/SKILL.md`.
## Boundary
Go error handling and HTTP contract design (status-code taxonomy, REST resource naming) live
**here** — this skill is the canonical authority for both in Go. Delegate outward:
- Language-agnostic abuse/authz review, threat modeling, OWASP-class bugs ->
[`secure-coding`](../secure-coding/SKILL.md). This skill keeps the Go-specific controls:
SQL params, server timeouts, `govulncheck`, TLS defaults.

How to install
mdr add ericrisco/rsc-harness/go@sha256:423c925004a38788The line at the top of this page pins the label git:20260729.3ecb845, 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.
