What it does
Golang package and module lookup via `godig`, a pkg.go.dev API client (CLI + MCP server). Use for any Go/Golang library's documentation, API signatures, symbols, usage examples, which versions exist, licenses, whether a dependency has CVEs, or who imports a package, prefer this over Context7 for any Go package or module. Read-only, no auth. Not for upgrading dependencies (→ See `samber/cc-skills-golang@golang-dependency-management` skill), choosing a library (→ See `samber/cc-skills-golang@golang-popular-libraries` skill), or local symbols and an already-used dependency's resolved source, call sites, and generic instantiations (→ See `samber/cc-skills-golang@golang-gopls` skill).
golang-pkg-go-dev
Dependencies: godig, go install github.com/samber/godig/cmd/godig@latest (or use a registered godig MCP server / the hosted instance instead).
godig queries the pkg.go.dev API. Use it to answer questions about Go packages and modules: docs, symbols, versions, importers and vulnerabilities. It works as a CLI and as an MCP server, and all operations are read-only and need no authentication.
When to use this skill
Trigger on questions like:
- "What versions of github.com/samber/lo are available?"
- "Does golang.org/x/text have known vulnerabilities?"
- "Show me the docs / symbols for package X."
- "Which packages import X?"
- "Search Go packages for Y."
Choosing between godig, gopls, Context7, and govulncheck
In short: godig answers questions about the published ecosystem (works even for packages not yet in your go.mod); gopls reasons about your locally resolved build (go.sum, including replaced forks); Context7 is a fallback for non-Go or unindexed docs; govulncheck is the whole-tree vulnerability audit (→ samber/cc-skills-golang@golang-security). See the samber/cc-skills-golang@golang-gopls skill for wiring gopls (MCP server, native LSP tool, and CLI) with Claude Code, and the samber/cc-skills-golang@golang-how-to skill's "godig vs gopls vs Context7 vs govulncheck" section for the full task-to-tool matrix.
Setup
Install
go install github.com/samber/godig/cmd/godig@latest
Register the MCP server (optional)
godig mcp runs over stdio by default, or streamable HTTP with --transport http. The command is harness-agnostic, any MCP-capable host can point at it. Claude Code registers it via its own CLI:
stdio (the client launches godig on demand):
claude mcp add pkg-go-dev -- godig mcp
streamable HTTP (shared server at /mcp, default :8080):
