gemini is a command for Claude Code from XinyuQu/llm-review. It costs 13 tokens per session (654 once invoked), scanned A, a copy of deepseek, Apache-2.0.

A command that sends your current code changes to Google Gemini for an adversarial review, meaning a review focused on finding weaknesses and problems.

In plain words
What is it for?
Use it to review staged changes or changes against a chosen Git reference, optionally limiting the review to the diff.
Why use it?
It provides another model's critique of the changes and can run in the background when a review may take several minutes.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

gemini 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 8d 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.

Origin

This is a copy

88% identical to deepseek — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Raw slash-command arguments: $ARGUMENTS

Parse $ARGUMENTS into the engine command (build as separate args, never splice the raw string into a shell line):

  • first bare word not starting with - → base git ref, pass as --base <ref>
  • --staged → review staged changes only
  • --diff-only → restrict the reviewer to the diff (don't let it read other repo files), pass as --diff-only
  • --wait → execution mode (don't pass to engine; foreground)
  • --background → execution mode (don't pass to engine; background)

Execution mode

Reviews against large diffs legitimately take several minutes. Default to background so the Claude Code session is not blocked.

  1. If $ARGUMENTS contains --wait: foreground, skip the question.
  2. If $ARGUMENTS contains --background: background, skip the question.
  3. Otherwise, estimate diff size first, then ask:
    • Run git diff --shortstat (or git diff --shortstat --staged if --staged, or git diff --shortstat <base>...HEAD if a base was given).
    • Tiny (≤2 files changed and no large directory rewrite) → recommend wait.
    • Otherwise → recommend background.
    • Call AskUserQuestion once with two options, recommended first and suffixed with (Recommended):
      • Wait for results
      • Run in background

Foreground path

Run synchronously:

node "${CLAUDE_PLUGIN_ROOT}/scripts/llm-review.mjs" review --provider gemini [--base <ref>] [--staged] [--diff-only]

Then present Gemini's review to the user verbatim — do not soften, summarize, or re-rank its findings. It is an independent second opinion; preserve its severities and verdict. If the command errored (e.g. missing API key or no changes), relay the error and point the user to /llm-review:setup.

Background path

Launch with Bash(run_in_background: true):

node "${CLAUDE_PLUGIN_ROOT}/scripts/llm-review.mjs" review --provider gemini --background [--base <ref>] [--staged] [--diff-only]

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.
