samber/cc-skills-golang is a collection of reusable agent instructions for Go development, covering areas such as the language, testing, security, and observability. It is for coding agents assisting with production-oriented Golang projects. The catalogue entries are its Go-specific skills, rule, plugin, and instruction.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00173 | $0.03442 |
| Opus 5.5 | $0.00069 | $0.01377 |
| Sonnet 5.5 | $0.00035 | $0.00688 |
| Haiku 4.5 | $0.00017 | $0.00344 |
Grade A, and why
golang-pkg-go-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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):
godig mcp --transport http --addr :8080
claude mcp add --transport http pkg-go-dev http://localhost:8080/mcp
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

golang-pkg-go-dev is a skill published in the GitHub repository samber/cc-skills-golang (3,692 stars, last pushed 5d ago), licensed MIT. It adds 173 tokens to every session and 3,442 once invoked, about $0.0007 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
