Source documentation, not instructions for this website. Review permissions before running any commands.
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.
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):
godig mcp --transport http --addr :8080
claude mcp add --transport http pkg-go-dev http://localhost:8080/mcp
Hosted instance (no install needed) — a public server runs at https://godig.samber.dev/mcp:
claude mcp add --transport http pkg-go-dev https://godig.samber.dev/mcp
Other MCP-capable harnesses (Cursor, Windsurf, and others) each have their own MCP server registration — an entry in their respective settings file pointing at the same godig mcp command or hosted URL, not a shared config format.
The CLI and the MCP server expose the same operations under matching names. Prefer the CLI when godig is installed; the hosted instance is a fallback when it is not.
Global flags (all commands): -o/--output table|json|raw|md (default table — pass -o md for chat), --base-url (pkg.go.dev API), --vuln-base-url (Go vulnerability database, consulted by vulns and overview), --timeout, --log-level debug|info|warn|error|off. All are also settable via GODIG_* env vars.

# 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](https://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 `replace`d 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
```bash
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):
```bash
claude mcp add pkg-go-dev -- godig mcp
```
streamable HTTP (shared server at `/mcp`, default `:8080`):
```bash
godig mcp --transport http --addr :8080
claude mcp add --transport http pkg-go-dev http://localhost:8080/mcp
```
Hosted instance (no install needed) — a public server runs at `https://godig.samber.dev/mcp`:
```bash
claude mcp add --transport http pkg-go-dev https://godig.samber.dev/mcp
```
Other MCP-capable harnesses (Cursor, Windsurf, and others) each have their own MCP server registration — an entry in their respective settings file pointing at the same `godig mcp` command or hosted URL, not a shared config format.
The CLI and the MCP server expose the **same** operations under matching names. Prefer the CLI when `godig` is installed; the hosted instance is a fallback when it is not.
## Commands
**Global flags (all commands):** `-o/--output table|json|raw|md` (default `table` — pass `-o md` for chat), `--base-url` (pkg.go.dev API), `--vuln-base-url` (Go vulnerability database, consulted by `vulns` and `overview`), `--timeout`, `--log-level debug|info|warn|error|off`. All are also settable via `GODIG_*` env vars.
| Command | Args | Specific flags | Purpose |
| --- | --- | --- | --- |
| `overview` | `<path>` | `--version` | Compact summary (metadata, versions, licenses, vulns) — start here |
| `search` | `<query>` | `--symbol --limit --filter` | Find packages (optionally exporting a symbol) |
| `package info` | `<path>` | `--module --version` | Package metadata |
| `package imports` | `<path>` | `--module --version` | Packages this package imports (plain list) |
| `package doc` | `<path>` | `--module --version --goos --goarch --format md\|text\|html\|markdown` | Full package doc (LARGE) |
| `package examples` | `<path>` | `--module --version --goos --goarch --symbol` | Runnable examples (LARGE; scope with `--symbol`) |
| `package licenses` | `<path>` | `--module --version` | License files, full text (LARGE) |
| `symbol doc` | `<path> <symbol>` | `--module --version --goos --goarch` | One symbol's signature + doc (token-efficient) |
| `symbol examples` | `<path> <symbol>` | `--module --version --goos --goarch` | One symbol's runnable examples |
| `symbols` | `<path>` | `--module --version --goos --goarch --limit --filter` | List exported symbols |
| `module info` | `<path>` | `--version` | Module metadata |
| `module licenses` | `<path>` | `--version` | Module license files (LARGE) |
| `module readme` | `<path>` | `--version` | Module README, full Markdown (LARGE) |
| `dependencies` | `<path>` | `--version` | go.mod deps: requires / replaces / excludes / go directive |
| `packages` | `<path>` | `--version --limit --filter` | Packages contained in a module |
| `versions` | `<path>` | `--limit --filter` | All versions, newest first |
| `major-versions` | `<path>` | `--limit --filter --exclude-pseudo` | Major versions (v1, v2 …) living as separate modules |
| `imported-by` | `<path>` | `--module --version --limit --filter` | Packages that import this one |
| `vulns` | `<path>` | `--version --limit` | Known vulnerabilities (from the Go vuln DB) |
| `mcp` | — | `--transport stdio\|http --addr --cache-ttl --cache-size` | Run as an MCP server |
| `version` | — | — | Print godig version / commit / build date |
When `godig` runs as an MCP server, each data command above is exposed as an operation of the same name.
**Exit codes:** `0` success, `1` runtime error (network, package not found), `2` usage error — a missing/invalid argument or flag (e.g. a non-positive `--limit`), or a command group invoked with no subcommand (`godig package`). Check for `2` to tell a malformed call apart from a failed lookup.
Full `-o md` output for every command: [sample-output.md](references/sample-output.md).
### Tips
- **Start with `overview`** — one call returns a compact summary (metadata, latest + recent versions, license types, vulnerabilities). Reach for `doc`/`examples`/`module readme`/`licenses` (LARGE) only when the full text is needed.
- **Always pass `-o md`** so results render as Markdown (tables, or raw doc/README) in the chat. Other formats exist (`table` default, `json`, `raw`) but prefer `md` here.
- `<path>` is a full import path, e.g. `github.com/samber/lo` — pass it as the positional argument.
- `--version` pins a specific module version (`v1.5.0`, `latest`, `master`, `main`); `--module` disambiguates which module a package belongs to.
- `--filter` narrows list results server-side with a Go boolean expression — see [Filter syntax](#filter-syntax).
- `--goos`/`--goarch` set the documentation/symbols build context (e.g. `linux`/`amd64`).
- Prefer `symbol doc`/`symbol examples` over the package-wide `package doc`/`package examples` when you only need one symbol — far fewer tokens.
- **Parallelize independent lookups** — every command is a self-contained, read-only HTTP query, so calls never depend on each other. When a task needs docs, examples, versions, or vulns for **several** symbols, packages, or modules, issue all the calls at once (multiple `godig` invocations in a single turn) rather than one after another — wall-clock drops from sum-of-latencies to slowest-single-call. For a large fan-out (documenting many symbols, comparing many candidate libraries, auditing CVEs across a dependency set), dispatch up to 5 parallel sub-agents, each running its own `godig` calls and returning a compact summary, so the raw LARGE output never lands in the main context.
- Listing commands auto-paginate (return all results); use `--limit` to cap.
### Filter syntax
`--filter` (on `search`, `versions`, `major-versions`, `packages`, `imported-by`, `symbols`) takes a **Go boolean expression evaluated server-side, once per result item**. It is not a regex — wrap the whole expression in single quotes for the shell.
- **Identifiers are the item's fields, which differ per command** — a field valid for one list is rejected by another (e.g. `search` exposes `packagePath`, not `path`). An unknown field fails with `undefined identifier: <name>` (HTTP 400), which names the offending field. Fields use the item's lowercase JSON key; the exception is enum-like values such as `kind`, which are capitalized (`Function`, not `func`).
- **Operators**: `==` `!=` `<` `<=` `>` `>=`, boolean `&&` `||` `!`, parentheses for grouping.
- **String functions**: `contains(s, sub)`, `hasPrefix(s, pre)`, `hasSuffix(s, suf)`.
- **Literals**: double-quoted strings (`"Function"`), `true`/`false`, numbers.
Filterable fields per command (string unless noted):
| Command | Fields |
| --- | --- |
| `search` | `modulePath`, `packagePath`, `synopsis`, `version` |
| `versions` | `version`, `modulePath`, `deprecated` (bool), `retracted` (bool), `hasGoMod` (bool), `commitTime` |
| `packages` | `path`, `name`, `synopsis`, `isRedistributable` (bool) |
| `imported-by` | `path` (the importing package path) |
| `symbols` | `name`, `kind` (`Function`/`Method`/`Type`/`Variable`/`Constant`), `synopsis`, `parent` |
| `major-versions` | `modulePath`, `major`, `version`, `isLatest` (bool) |
