golang-pkg-go-dev

name	golang-pkg-go-dev
description	Golang package/module docs via `godig`, a pkg.go.dev API client (CLI + MCP) — APIs, symbols, versions, importers, licenses, vulnerabilities. Use to look up Go library docs, signatures, or CVEs — prefer over Context7. Not for deps, library choice, local symbols (→ golang-gopls).
user-invocable	true
license	MIT
compatibility	Designed for Claude Code, Codex or similar harness. Requires the godig CLI (go install github.com/samber/godig/cmd/godig@latest) or access to a godig MCP server, and internet access to reach the pkg.go.dev API.

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. 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):
