golang-cli-review

golang-cli-review is a skill for Claude Code from asteroid-belt/skulto. It costs 79 tokens per session (716 once invoked), scanned A, original, MIT.

A review checklist for Go command-line programs, which are tools operated through a terminal. It checks their structure, errors, flags, output, tests, performance, security, and common Go practices.

In plain words
What is it for?
Use it to review a Go terminal application and produce actionable findings about its command framework, help text, inputs, exit codes, output formats, secrets, and security.
Why use it?
It helps find confusing commands, weak error handling, unsafe behavior, and missing test coverage before the program is released.

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-review 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 11d 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.

Go CLI Code Review

Review Go CLI applications and produce an actionable checklist of findings.

Review Workflow

  1. Gather code - Read all Go files in the CLI project
  2. Analyze - Evaluate against review categories (see below)
  3. Produce checklist - Use template from references/review-checklist.md

Review Categories

Evaluate each area systematically:

CLI Structure & Framework

  • Framework usage (prefer Cobra for complex CLIs)
  • Command hierarchy and discoverability
  • Help text quality with examples
  • Version command following semver

Error Handling

  • RunE vs Run (must return errors)
  • Error wrapping with %w and context
  • User-facing error actionability
  • Meaningful exit codes (0=success, 1=error, 2=usage)
  • No panics in normal paths

Flag & Argument Design

  • Lowercase-kebab-case naming
  • Short flags for common options (-v, -o, -q)
  • Required flags marked and validated early
  • Sensible defaults
  • Clear descriptions

Input/Output

  • stderr for errors/progress, stdout for data
  • Machine-readable output support (--json, --format)
  • Quiet and verbose mode support
  • Non-TTY mode handling (no prompts)

Security

  • Secrets via env vars or files, never flags
  • Path traversal prevention
  • No shell injection
  • URL scheme validation
  • No sensitive data in logs

Testing

  • Command-level unit tests
  • Error path coverage
  • Integration tests for critical flows

Performance & Resources

  • Context-based cancellation
  • Signal handling (SIGINT/SIGTERM)
  • Proper resource cleanup (defer)
  • No goroutine leaks

Go Idioms

  • Effective Go style compliance
  • Immediate error handling
  • Package naming conventions
  • Interface/struct patterns

Reference Material

For patterns and examples, see references/cli-patterns.md.

What ships with it

2 files 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.
