powershell-cli-review

powershell-cli-review is a skill for Claude Code, Codex from alonf/specrew. It costs 20 tokens per session (387 once invoked), scanned A, original, MIT.

A test procedure for PowerShell command-line scripts that advertise GNU-style options such as --dry-run.

In plain words
What is it for?
Use it to run the exact commands users will run and verify exit codes, echoed paths, prompt-free output, and dry-run behavior.
Why use it?
It reveals when documented flags do not bind, default paths are used, prompts appear, or dry runs change the filesystem.

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

powershell-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 3d 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

Context

Use this when a standalone PowerShell script documents GNU-style --flag arguments. The acceptance question is not whether aliases or parser code look plausible, but whether live invocation binds the documented surface without prompting or silently falling back to defaults.

Patterns

  • Test the exact advertised direct form: & .\script.ps1 --flag ....
  • Also test powershell -NoProfile -File .\script.ps1 --flag ... when Windows PowerShell host behavior matters.
  • Capture output as text with nested PowerShell plus Out-String so summary tables can be searched reliably.
  • Verify four conditions together: exit code, requested path echoed in output, no fallback default path, and no interactive prompt text.
  • For --dry-run, confirm the requested target directory still does not exist after the run.

Examples

  • & .\scripts\specrew-init.ps1 --dry-run --force --project-path C:\Repo\review-target
  • powershell -NoProfile -File .\scripts\specrew-init.ps1 --dry-run --force --project-path C:\Repo\review-target

Anti-Patterns

  • Trusting parameter aliases or fallback-parser code without a live invocation.
  • Validating only PowerShell-native switches (for example -DryRun) when the contract advertises --dry-run.
  • Calling a dry-run successful when it quietly targeted the current working directory instead of the requested path.

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.
