golang-refactoring
by samber
"Golang refactoring — safe, at-scale restructuring of existing Go code: a coverage-adaptive safety net, behavior-preserving transforms (gopls Rename/Extract, gofmt -r, gopatch), the Fowler catalog mapped to Go, breaking import cycles, and small stacked PRs. Apply when a function or type has grown too large, a code smell blocks a feature, or the user asks to refactor Go code — also for renaming at scale, extracting functions or interfaces, moving code between packages, or planning a multi-step refactor. Target styles owned elsewhere → See samber/cc-skills-golang@golang-naming (renames), samber/cc-skills-golang@golang-project-layout (splits), samber/cc-skills-golang@golang-modernize (idioms), samber/cc-skills-golang@golang-code-style (control flow), samber/cc-skills-golang@golang-design-patterns (patterns/DI)."
golang-safety
by samber
"Defensive Golang coding against accidental bugs — nil panics, typed-nil interfaces, append backing-array aliasing, silent int64-to-int32 truncation, float == comparison, defer inside loops, defensive copies of slices and maps, and usable zero values. Use when a Go program panics on a nil map write or nil pointer dereference, when reviewing code for nil-safety, numeric conversion overflow, or resource lifecycle, or when designing a type whose zero value must be safe. Not for designing concurrent access with goroutines, channels, or sync primitives (→ See samber/cc-skills-golang@golang-concurrency skill), not for exploitable vulnerabilities such as injection, weak crypto, or leaked secrets (→ See samber/cc-skills-golang@golang-security skill), and not for debugging an already-failing program (→ See samber/cc-skills-golang@golang-troubleshooting skill)."
golang-error-handling
by samber
"Idiomatic Golang error handling — creation, wrapping with %w, errors.Is/As, errors.Join, custom error types, sentinel errors, panic/recover, the single handling rule, structured logging with slog, HTTP request logging middleware, and samber/oops for production errors. Built to make logs usable at scale with log aggregation 3rd-party tools. Apply when creating, wrapping, inspecting, or logging errors in Go code. For samber/oops specifics → See samber/cc-skills-golang@golang-samber-oops skill; for slog handler ecosystem → See samber/cc-skills-golang@golang-samber-slog skill."
golang-code-style
by samber
"Golang code style conventions — line length and breaking, variable declarations, control flow clarity, when comments help vs hurt. Use when writing or reviewing Go code, asking about style or clarity, or establishing project coding standards. Not for naming conventions (→ See samber/cc-skills-golang@golang-naming skill), linter configuration (→ See samber/cc-skills-golang@golang-lint skill), or doc comments (→ See samber/cc-skills-golang@golang-documentation skill)."
golang-security
by samber
"Security best practices and vulnerability prevention for Golang — injection (SQL, command, XSS), cryptography, path traversal, SSRF and HTTP security headers, cookies, secrets management, memory safety, PII in logs, STRIDE/DREAD threat modeling, plus gosec SAST, race detection, and fuzz testing. Apply when writing, reviewing, or auditing Go code for security, or when touching crypto, file or network I/O, secrets, user input, or authentication. Not for non-exploitable defensive bugs such as nil panics or slice aliasing (→ See samber/cc-skills-golang@golang-safety skill), dependency vulnerability scanning with govulncheck (→ See samber/cc-skills-golang@golang-dependency-management skill), or wiring security scanners into CI pipelines (→ See samber/cc-skills-golang@golang-continuous-integration skill)."
golang-concurrency
by samber
"Golang concurrency design — goroutine lifecycle and leak prevention, channels and select, channel ownership and direction, sync.Mutex/RWMutex/sync.Map/sync.Once/atomics, errgroup, singleflight, worker pools, and fan-out/fan-in pipelines. Use when writing or reviewing concurrent Go code, when choosing between channels and mutexes, when protecting a shared map or counter, or when a goroutine has no clear exit. Not for defensive coding unrelated to concurrency such as nil panics, slice aliasing, or numeric overflow (→ See samber/cc-skills-golang@golang-safety skill), and not for debugging a specific hung, crashing, or racing program after the fact (→ See samber/cc-skills-golang@golang-troubleshooting skill)."
golang-how-to
by samber
"Golang skills orchestrator — always active on any Golang coding, review, debug, or setup task. Reads the task context and loads the most relevant skills from samber/cc-skills-golang, often multiple at once: writing a gRPC service loads golang-grpc + golang-testing + golang-error-handling; debugging a panic loads golang-troubleshooting + golang-safety; auditing security loads golang-security + golang-lint + golang-safety. Also: disambiguates competing clusters when two skills seem to overlap (performance vs benchmark vs troubleshooting, samber/lo vs mo vs ro, DI cluster, safety vs security), and configures the project's agent-config file (CLAUDE.md, AGENTS.md, GEMINI.md, Cursor rules, or Copilot instructions) to force-trigger skills in a project (/golang-how-to configure)."
golang-modernize
by samber
"Modernize Golang code to use recent language features, standard library improvements, and idiomatic patterns. Use when reviewing Go code with old-style patterns, when encountering a deprecation warning, or when the user asks for modernization, a Go version upgrade (e.g. to Go 1.27), or a CI/tooling refresh. Not for structural refactors, extracting functions, or moving code between packages (→ See samber/cc-skills-golang@golang-refactoring skill)."
