version: "1.0.2" name: golang-how-to description: "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 CLAUDE.md or AGENTS.md to force-trigger skills in a project (/golang-how-to configure)." user-invocable: true license: MIT compatibility: Designed for Claude Code or similar AI coding agents.

Persona: You are a Go skills orchestrator. For every Go task, identify all relevant skills and load them together — a task rarely belongs to a single skill.
Dependencies: gopls — go install golang.org/x/tools/gopls@latest; the built-in LSP tool also needs ENABLE_LSP_TOOL=1 and a Go language server wired (see Code navigation with gopls).
Modes:
- Orchestrate — for any Go coding, review, debug, or setup task, load the primary skill plus all applicable secondary skills simultaneously.
- Disambiguate — when two skills seem to overlap, show the boundary table. See disambiguation.md.
- Configure — write the always-load directive for
golang-how-toitself, plus an optional## Required Go skillsblock, to the project'sCLAUDE.mdorAGENTS.md. Follow project-config.md.

Code navigation with gopls
gopls gives semantic code intelligence for Go — go-to-definition, find references, diagnostics, package API, symbol search, refactoring. → See samber/cc-skills-golang@golang-gopls skill for the three ways to reach it (its own MCP server, the native LSP tool, and its CLI), the full capability matrix, and efficient read/edit workflows.
gopls only reasons about code that is present and resolvable in the local build: your workspace plus every dependency exactly as pinned in go.sum (including replace directives). For any fact that isn't tied to your local build — version history, licenses, ecosystem-wide importers, a package you haven't added yet — use golang-pkg-go-dev (godig). See the godig vs gopls vs Context7 vs govulncheck section below for the full boundary.
godig vs gopls vs Context7 vs govulncheck
Four tools can answer "is this dependency OK to use," and they don't overlap as much as they look:
- Context7 is a general-purpose, cross-language documentation fetcher — useful when no more specific source exists. For a Go package or module,
godigis almost always the better choice: it pulls structured, Go-specific data straight from pkg.go.dev — exact versions, exported symbols with signatures, runnable examples,imported-by, and known vulnerabilities — rather than Context7's generic scraped/curated docs, which don't expose that structure and can lag or miss lesser-known Go modules. Reach for Context7 only when a dependency's documentation genuinely doesn't exist or isn't indexed on pkg.go.dev. - `godig` answers questions about the published ecosystem: any Go package or module, whether or not it's in your
go.modyet — it calls the remote pkg.go.dev API and never touches your local checkout. Itsvulnscommand reports CVEs known for a package/version in isolation, regardless of whether your build actually reaches the vulnerable code path. - `gopls` (→
samber/cc-skills-golang@golang-gopls, via its MCP server, the nativeLSPtool, or its CLI) answers questions about your specific build: your code plus every dependency exactly as pinned ingo.sum, includingreplacedirectives pointing at forks or local paths — neithergodignor Context7 can see that. Itsgo_vulncheckoperation runs a single, on-demand reachability check against the workspace as it stands right now. - `govulncheck` (the standalone CLI, wrapped by the
samber/cc-skills-golang@golang-securityskill) is the whole-tree audit: it walks the entire module's call graph to confirm which known vulnerabilities are actually reachable, and is the tool of record for CI gates and periodic security sweeps —gopls'sgo_vulncheckis a lighter-weight, single-shot version of the same analysis for use mid-edit.
Pick by task:
| Task | Tool | How | |
|---|---|---|---|
| Find where a symbol is defined in your own repo | gopls | samber/cc-skills-golang@golang-gopls — go_search, then go_file_context | |
| Understand a file's intra-package dependencies | gopls | samber/cc-skills-golang@golang-gopls — go_file_context | |
Jump into a dependency's exact resolved source (incl. forks/replaced versions) | gopls | samber/cc-skills-golang@golang-gopls — go_package_api, or the native LSP tool's goToDefinition | |
| Find every call site in your own code that references a dependency's symbol | gopls | samber/cc-skills-golang@golang-gopls — go_symbol_references — godig's imported-by only lists public _packages_, not call sites in your repo | |
| Get compiler diagnostics right after an edit | gopls | samber/cc-skills-golang@golang-gopls — go_diagnostics (MCP), or automatic with the native LSP tool | |
| Check whether your current build can reach a known vulnerability, mid-edit | gopls | samber/cc-skills-golang@golang-gopls — go_vulncheck | |
| Rename, extract, inline, or otherwise refactor local code | gopls | samber/cc-skills-golang@golang-gopls — safe rename, refactor.* code actions | |
| Whole-tree vulnerability audit across the module (CI, periodic sweep) | govulncheck | samber/cc-skills-golang@golang-security skill — govulncheck ./... | |
| List available versions of a published package | godig | godig versions <path> | |
| Check known CVEs for a package/version you haven't added yet | godig | godig vulns <path> | |
| See exported symbols/signatures of a published package | godig | godig symbols / symbol doc | |
| Get runnable code examples for a symbol | godig | godig symbol examples | |
| Read a package's rendered README/docs | godig | godig module readme / package doc | |
| See who imports a package across the whole public ecosystem | godig | godig imported-by | |
| Search for a package or library candidate | godig | godig search | |
| Check a package's or module's license | godig | godig package licenses / module licenses | |
| Get docs for a non-Go library, or a Go module not indexed on pkg.go.dev | Context7 | resolve-library-id / query-docs |
See the samber/cc-skills-golang@golang-pkg-go-dev skill for the full godig command reference, and the samber/cc-skills-golang@golang-security skill for the whole-tree govulncheck remediation workflow.

Configure mode
Write an always-load directive for golang-how-to itself to a project's CLAUDE.md or AGENTS.md, and optionally force-trigger specific secondary skills too.
samber/cc-skills-golang@golang-project-layout writes the always-load directive automatically at project creation, with no user confirmation needed — it costs one skill description and never imposes project-specific choices. Running /golang-how-to configure writes it too if missing, and additionally lets the user confirm a ## Required Go skills block for skills that must always apply beyond routing. Follow project-config.md.
This skill is not exhaustive. Refer to individual skill files and the official Go documentation for detailed guidance.
