review-cli-changes

review-cli-changes is a skill for Claude Code from tomzx/agents. It costs 80 tokens per session (4,682 once invoked), scanned A, original, MIT.

A static review guide for changes to a command-line interface, the text-based way users run a program with commands and options. It checks whether new or changed commands, output, errors, and exit codes fit the existing interface.

In plain words
What is it for?
Use it on a pull request, branch, or diff that changes CLI commands, flags, arguments, configuration behavior, output, or shell integration.
Why use it?
It helps find changes that could break scripts, confuse users, or behave differently from other commands before release. It does not run the CLI, so runtime claims need a separate check.

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

review-cli-changes 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 7d 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.

Review CLI Changes

Reviews a change to a command-line interface and reports findings. It answers one question: is this CLI change safe to ship? Covering compatibility with the existing surface, consistency across commands, option and argument handling, output behavior, exit codes, error handling, configuration precedence, and shell integration.

It is the change-time counterpart to /review-cli-design: that skill reviews a cli-design.md artifact before implementation, this one reviews the implemented diff. General code craft stays with /review-pr; criteria conformance stays with /verify-pr. This review is static: it does not build or run the CLI, so a claim that needs the CLI executed is /verify-pr's to prove.

Prerequisites

  • Apply the shared SDLC conventions in skills/sdlc/references/shared.md (PR Review Reports for report location and posting rules).
  • Apply the shared evidence standard in ../sdlc/references/evidence.md. Static claims carry L1 - Cited or L2 - Ruled out; a decisive claim proven by a read-only command can reach L3 - Executed. Behavior observed by running the CLI is /verify-pr's L4 - Reproduced.
  • The change to review, in one of these forms:
    • a PR number plus repository (/review-cli-changes 42 acme/cli),
    • a git diff ref (for example origin/main..HEAD),
    • a worktree directory, or a changeset already in context.
  • The CLI's existing surface at the base revision, so the before/after can be compared (read with git show <base>:<path>).
  • .sdlc/features/N-<slug>/cli-design.md when one exists (optional; used for surface-vs-design checks).
  • Grep access to the codebase for the CLI framework, its option definitions, and its test suite.

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.
