sota-golang — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited sota-golang (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Expert-level rules for producing and auditing production Go. Target a supported Go release: Go supports the two latest majors (1.25 left support when 1.27 shipped, 2026-08) — verify the supported pair at go.dev/doc/devel/release. Feature notes: loop-var scoping from 1.22, b.Loop/os.Root/tool directives from 1.24, testing/synctest and container-aware GOMAXPROCS from 1.25, errors.AsType and the default-on Green Tea GC from 1.26, the GA goroutineleak profile and encoding/json backed by v2 from 1.27 — noted where relevant. Every rule states the why; every rules file ends with an audit checklist of grep/vet/lint patterns.

| Severity | Meaning | Examples |
|---|---|---|
| CRITICAL | Exploitable or guaranteed-incorrect in production | SQL built with fmt.Sprintf, command injection via sh -c, unbounded goroutine leak on hot path, InsecureSkipVerify: true, data race confirmed by -race |
| HIGH | Likely production incident or security weakness | Missing http.Server timeouts, no ctx cancellation on blocking goroutine, unchecked integer truncation on attacker input (G115), resp.Body never closed, panic for control flow in a server |
| MEDIUM | Correctness/maintainability hazard, latent bug | Error strings compared with strings.Contains, context stored in struct, time.After in a loop, map writes without lock under suspected concurrency, missing errors.Is/As |
| LOW | Idiom/perf debt, works but wrong shape | Returning interfaces, util package dumps, missing preallocation on hot path, non-table tests, no t.Parallel |
| INFO | Style, doc, or hygiene note | Naming, missing doc comments, gofumpt drift |

| File | Read this when... |
|---|---|
rules/01-errors.md | Writing/reviewing any error path: wrapping with %w, errors.Is/As, sentinel vs typed errors, in-band sentinels (absence encoded as `-1`/`0`/`""`) and comma-ok, panic/recover policy, error API design for libraries vs apps |
rules/02-design.md | Designing packages or APIs: interface placement and size, package layout and internal/, naming, zero values, generics restraint, embedding, functional options, context.Context discipline, numeric edges (NaN/Inf from ParseFloat, integer divide-by-zero, MinInt / -1) |
rules/03-concurrency.md | Anything with go, chan, sync, or select: goroutine lifecycle ownership, leak catalog, errgroup fan-out, channels-vs-mutex decision, race patterns, worker pools, semaphores, time.After traps |
rules/04-http-services.md | Building or auditing HTTP servers/clients: all five server timeouts, client timeouts and body hygiene, connection reuse, graceful shutdown, middleware, CSRF via http.CrossOriginProtection (and its bypass/trusted-origin exceptions), JSON duplicate-key probe, cookie attributes (framework helper defaults), debug mode and /debug/* endpoints in production, explicit Content-Type (no body sniffing), slog structured logging, request-scoped values |
rules/05-security.md | Any input crossing a trust boundary: SQL parameterization, os/exec safety, path traversal and os.Root, integer overflow (G115), output encoding (html/template), CSPRNG (crypto/rand vs math/rand), FIPS 140-3 mode (GOFIPS140, GODEBUG=fips140), TLS config, SSRF (dial-time IP check via net.Dialer.ControlContext, redirects, proxy), dynamic code evaluation (template text from input, embedded interpreters, expr env), unsafe/cgo policy (govulncheck, supply chain and go.sum moved to rules/08) |
rules/06-performance.md | Latency/memory work: pprof workflow, testing.B + b.Loop, allocation reduction, strings.Builder, sync.Pool criteria, escape analysis, GOGC/GOMEMLIMIT, PGO |
rules/07-tooling-ci.md | Setting up or auditing CI and tests: golangci-lint curated config, staticcheck/gofumpt/vet, table tests, t.Parallel correctness, testcontainers, golden files, fuzzing, go.mod hygiene and tool directives, dependency adoption (selection checks, insecure library defaults). *Test strategy — suite shape, TDD, doubles, test data, flake policy — lives in [`sota-testing`](../sota-testing/SKILL.md); load it for any build that writes logic. This file owns Go runner mechanics only.* |
rules/08-supply-chain.md | Adding or auditing dependencies and the module supply chain: the checksum database, govulncheck, code that runs at build time (go:generate, cgo flags, -toolexec, GOTOOLCHAIN), keeping the toolchain current (formerly rules/05 section 8, now §1); GODEBUG settings from the go line, godebug blocks, //go:debug and the environment that weaken TLS/x509/archive defaults (§2) |
discarded with _, never logged-and-ignored on a path that must abort. Compare with errors.Is/errors.As, never string matching. (rules/01)
panic is for unreachable programmererrors only; servers recover at goroutine boundaries and log. (rules/01)
context.Context, a closed channel, or a WaitGroup/errgroup join. If you can't say how it stops, don't start it. (rules/03)
CRITICAL finding, not flaky-test noise. (rules/03, rules/07)
http.Server sets ReadHeaderTimeout, ReadTimeout, WriteTimeout,IdleTimeout; clients set timeouts and defer resp.Body.Close() (plus a bounded drain before 1.27).** Default zero timeouts are a DoS. (rules/04)
database/sql placeholders, pgx,or sqlc-generated code). String-built SQL is CRITICAL, no exceptions for "internal" values. (rules/05)
os/exec with argv lists, never sh -c with interpolated input;file paths validated against a root** (os.Root on 1.24+, else filepath.Clean + prefix check after resolving symlinks). (rules/05)
context.Context is the first parameter, flows down, is never stored ina struct**, and carries only request-scoped metadata — never dependencies. (rules/02)
keep them small.** No premature interfaces "for mocking". (rules/02)
go.sum committed;~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
