What is gemini-review?

A code-review skill that uses Google's Gemini command-line tool to inspect local Git changes or a pull request. It provides a second AI review from a different system.

Use it to review uncommitted or committed changes, inspect a pull request, and cross-check another code review with Gemini.

A second review can reveal issues the original author or another AI missed. It is useful when you want an independent or deliberately challenging check of a change.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00072	$0.00806
Opus 5	$0.00036	$0.00403
Sonnet 5	$0.00014	$0.00161
Haiku 4.5	$0.00007	$0.00081

Security

Grade A, and why

gemini-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 11d 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 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.
