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.
Passed 19 of 22 test cases with the skill, and 7 of 22 without it.

One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
By default, when running queries with the Go package registry tool `godig`, the output comes back in plain text tables. Which global flag should always be passed when retrieving output intended for chat display so that doc comments and package lists render properly?
| Checked | Without skill | With skill |
|---|---|---|
| Passes `-o md` for chat Markdown rendering. | Missed | Passed |
| Replaces default plain text table formatting with Markdown output for chat. | Passed | Passed |

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.
Trigger on questions like:
godig, gopls, Context7, and govulncheckIn 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.
go install github.com/samber/godig/cmd/godig@latest
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):
