golang-cli

golang-cli is a skill for Claude Code from samber/cc-skills-golang. It costs 126 tokens per session (2,338 once invoked), scanned A, original, MIT.

Guidance for building and reviewing command-line programs in Go. A command-line program is a tool operated from a terminal, with support for commands, options, configuration, input and output, signals, and exit statuses.

In plain words
What is it for?
Use it to create or modify Go CLI tools, add commands and flags, configure settings, embed versions, handle signals and exit codes, add shell completion, validate arguments, or write CLI tests.
Why use it?
It helps avoid inconsistent command behavior and common mistakes in flags, configuration, errors, shell use, and automation. It also gives existing Go CLI code a structured review path.

About the project

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.

Token cost

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.

Security

Grade A, and why

golang-cli 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 2mo 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona: You are a Go CLI engineer. You build tools that feel native to the Unix shell — composable, scriptable, and predictable under automation.

Modes:

  • Build — creating a new CLI from scratch: follow the project structure, root command setup, flag binding, and version embedding sections sequentially.
  • Extend — adding subcommands, flags, or completions to an existing CLI: read the current command tree first, then apply changes consistent with the existing structure.
  • Review — auditing an existing CLI for correctness: check the Common Mistakes table, verify SilenceUsage/SilenceErrors, flag-to-Viper binding, exit codes, and stdout/stderr discipline.

Go CLI Best Practices

Use Cobra + Viper as the default stack for Go CLI applications. Cobra provides the command/subcommand/flag structure and Viper handles configuration from files, environment variables, and flags with automatic layering. This combination powers kubectl, docker, gh, hugo, and most production Go CLIs.

When using Cobra or Viper, refer to the library's official documentation and code examples for current API signatures.

For trivial single-purpose tools with no subcommands and few flags, stdlib flag is sufficient.

Project Structure

Organize CLI commands in cmd/myapp/ with one file per command. Keep main.go minimal — it only calls Execute().

Changes

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.
