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 — add a
## 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. godiganswers questions about the published ecosystem: any Go package or module, whether or not it's in yourgo.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 thesamber/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.
