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 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 $ARGUMENTS into the shell command. Build the arguments yourself.
  • Drop --wait and --background from the raw arguments. Pass --json as its own argument.
  • If the raw arguments include --model <id>, pass --model and the ID as two arguments, with the ID single-quoted. Leave --model out 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 Bash in the background, even when the raw arguments include --wait. A review of a few short claims can take more than 10 minutes, and a foreground Bash call 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.

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.
