Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.00843 |
| Opus 5.5 | $0.00005 | $0.00337 |
| Sonnet 5.5 | $0.00003 | $0.00169 |
| Haiku 4.5 | $0.00001 | $0.00084 |
Grade A, and why
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 29d 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
Run a grounded fact-check of content from the current conversation via agy --print (Antigravity CLI). The agent runs live web searches and returns structured findings: which claims are supported, uncertain, or contradicted, with source URLs, plus any reasoning issues.
Raw slash-command arguments:
$ARGUMENTS
Core constraint:
- This command is analysis-only.
- Do not fix issues, edit files, or change your answer.
- Your only job is to run the review and return Gemini's output verbatim to the user.
Input handling:
- Determine what to review from the user's message and conversation context:
- If the user points at specific content (e.g., "review your last reply", "check the second bullet above", "review the paragraph starting with...", "review what I just pasted"), pass exactly that content.
- If another skill or agent calls this command and gives you the text to review, review exactly that text.
- Otherwise, default to the full text of your immediately previous assistant turn.
- Pass the selected content verbatim via stdin using a quoted heredoc. Do not paraphrase or abridge it.
- If there is nothing suitable to review (e.g., the user gave no reference and this is the first message of the session), stop and tell the user: "Nothing to review. Point me at the text you want audited (e.g., 'review your last reply' or paste the content), then rerun /gemini:review."
Building the command:
- Do not paste
$ARGUMENTSinto the shell command. Build the arguments yourself. - Drop
--waitand--backgroundfrom the raw arguments. Pass--jsonas its own argument. - If the raw arguments include
--model <id>, pass--modeland the ID as two arguments, with the ID single-quoted. Leave--modelout when the caller gave none. The plugin then uses its default model. - Pass the rest of the raw arguments (the focus text) as ONE single-quoted argument. Write each
'inside it as'\''. Leave it out when there is no focus text. - Example: for the raw arguments
check Node's "LTS" date, the arguments are'check Node'\''s "LTS" date'. - Example: for the raw arguments
--model gemini-4-argon-medium focus on dates, the arguments are--model 'gemini-4-argon-medium' 'focus on dates'.
Flow:
- Always launch the review with
Bashin the background, even when the raw arguments include--wait. A review of a few short claims can take more than 10 minutes, and a foregroundBashcall stops at 10. - Use a quoted heredoc, so the content is piped in literally with no shell expansion:
Bash({
command: `node "${CLAUDE_PLUGIN_ROOT}/scripts/gemini-companion.mjs" review 'check the "LTS" date' <<'GEMINI_REVIEW_INPUT_EOF'
<the full text of the content to review, verbatim>
GEMINI_REVIEW_INPUT_EOF`,
description: "Gemini review",
run_in_background: true
})
- After launching, tell the user: "Gemini review started in the background. You will be notified when it finishes." Then stop. If you are a subagent, do not send your final report yet: a subagent sends only one report, so a report sent now loses the review output. You are woken when the task finishes.
- When it finishes, return its stdout verbatim, exactly as-is.
- Do not paraphrase, summarize, or add commentary before or after it.
- Do not edit any file or follow up on any finding.
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.

review is a command published in the GitHub repository stevenc81/gemini-plugin-cc (0 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 13 tokens to every session and 843 once invoked, about $0.0001 per session on Opus 5.5. 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.
