| name | golang-pkg-go-dev |
| description | Golang package and module documentation and exploration via `godig`, a pkg.go.dev API client (CLI + MCP server) — package docs, API references, symbols, code examples, available versions, importers (who imports a package), licenses, and known vulnerabilities. Read-only, no auth. Use for looking up any Go/Golang library's documentation, API signatures, usage examples, which versions exist, whether a dependency has CVEs, or who imports a package — prefer this over Context7 for any Go package or module. Triggers on: how to use a Go library, Go API docs, import usage, code examples, pkg.go.dev. Not for upgrading dependencies (→ See `samber/cc-skills-golang@golang-dependency-management` skill) or choosing a library (→ See `samber/cc-skills-golang@golang-popular-libraries` skill). Not for local symbols, or for navigating an already-used dependency's resolved source, call sites, or generic instantiations — → See `samber/cc-skills-golang@golang-gopls` skill for those. |

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. 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.
stdio (the client launches godig on demand):
claude mcp add pkg-go-dev -- godig mcp
streamable HTTP (shared server at /mcp, default :8080):
godig mcp --transport http --addr :8080
claude mcp add --transport http pkg-go-dev http://localhost:8080/mcp
