golang — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited golang (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 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.

This skill synthesizes the absolute best practices from the ecosystem (Uber Guide, Google Guide, and community consensus) to ensure written Go code is idiomatic, performant, and safe.
context.Context must always be the first parameter of any function doing I/O or asynchronous work.context.Context inside structs. It is meant to flow entirely through the function stack.context.WithValue for request-scoped data (like trace IDs, user claims). Never use it to pass databases, loggers, or configuration.fmt.Errorf("doing operation: %w", err) to preserve the underlying error for errors.Is or errors.As. Use %v only if you explicitly want to hide the underlying error's identity.var ErrNotFound = errors.New(...)). Use errors.Is(err, ErrNotFound) rather than string comparisons.sync.WaitGroup to wait for a pool of workers.chan to pass ownership of data between concurrent routines.sync.Mutex to protect shared state accessed from multiple routines.Get prefixes for getters. If a struct has an Owner field, the getter is Owner(), not GetOwner(). The setter would be SetOwner().user.UserConfig, log.Logger.user.Config, log.Entry.-er (Reader, Writer, Formatter).idx instead of index, b instead of buffer, r instead of reader).make([]T, 0, capacity) or make(map[K]V, capacity) when the target size is known. This dramatically reduces heap allocations during append loops.nil slice (var names []string) is idiomatically correct, functionally identical to a zero-length slice, and requires zero allocations. Use it over names := []string{} unless JSON formatting explicitly demands an empty array [] instead of null.[]struct{ name string ... } iterated via t.Run() for clear, modular test cases.t.Helper() so test runner output points to the actual failure site, not the inside of the utility function.go fmt ./... and golangci-lint run (if available) before confirming code completion.exec.Command. Never pass unsanitized user input to the shell.db.QueryRow("SELECT * FROM users WHERE id = ?", id)).filepath.Clean before filepath.Join to prevent directory escape vulnerabilities.~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
