go-cli-development

go-cli-development is a skill for Claude Code, Codex from CassianFlorin/skill-hub-registry. It costs 0 tokens per session (157 once invoked), scanned A, original, MIT.

A set of rules for changing a Go command-line application, meaning a program operated by typing commands in a terminal.

In plain words
What is it for?
Use it when developing Go CLI commands, especially parsers, filters, formatters, machine-readable output, builds, and automated tests.
Why use it?
It helps keep command behavior, errors, output, formatting, and tests consistent while code is changed.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Not installable on its own: it runs a file from its repository that does not travel with it. Clone the repository, or install whatever ships that file. The line is go build -v ./cmd/<binary>.

Install

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex.

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

go-cli-development 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 5d 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.

What it actually says

Go CLI Development

Use this skill when changing a Go command-line application.

Instructions

  • Start from the command behavior and its tests.
  • Prefer table-driven tests for parser, filter, and formatter behavior.
  • Keep command output stable and easy to parse.
  • Return errors from command handlers instead of exiting deep in library code.
  • Use gofmt before final verification.
  • Run targeted tests first, then the full suite and build.

Verification

go test ./...
go build -v ./cmd/<binary>
git diff --check

Output Design

  • Use tabs for machine-readable list output.
  • Include enough fields for users to decide the next command.
  • Keep detailed metadata in info commands rather than crowded list views.
Files

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.

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.

go-cli-development is a skill published in the GitHub repository CassianFlorin/skill-hub-registry (2 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 157 tokens. 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 2026-08-31.
