What is gemini-setup?

A guided setup command for connecting code reviews to Gemini, Google's AI model service.

Installing and logging into Gemini's command-line tool, or configuring Gemini reviews with an API key.

It checks available connection methods and guides either command-line subscription login or API-key setup.

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	$0.00034	$0.00822
Opus 5	$0.00017	$0.00411
Sonnet 5	$0.00007	$0.00164
Haiku 4.5	$0.00003	$0.00082

Security

Grade C, and why

gemini-setup scanned grade C with 3 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.

A mod that escalates privileges can change anything on the machine, not only the project.

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

What it actually says

Guided setup for the gemini provider. Follow this exactly; do not improvise extra steps.

Step 1 — probe status:

node "${CLAUDE_PLUGIN_ROOT}/scripts/llm-review.mjs" setup --provider gemini --json

Parse the JSON: mode, cli (command, installed, installCmd, login), api (hasKey, primaryEnv, keyHelp), ready, resolvedTransport, reviewCommand.

Step 2 — if already ready: tell the user it's set up via resolvedTransport, then AskUserQuestion once: Keep current setup vs Reconfigure. If keep → show status and stop.

Step 3 — choose a path by mode:

api-only → API KEY FLOW.
cli-only → SUBSCRIPTION FLOW.
both → AskUserQuestion exactly once: "How do you want to connect to Gemini?" with options, first one suffixed (Recommended):
- Subscription via the {cli.command} CLI (Recommended) — reuses your existing login, usually cheaper for heavy use
- API key — pay-per-token HTTP API

SUBSCRIPTION FLOW:

If cli.installed is false and cli.installCmd is set: AskUserQuestion once — Install {cli.command} now (Recommended) vs Skip for now. If install, run cli.installCmd via Bash, then re-run the Step 1 probe. If skip, present status and stop.
Persist the choice: node "${CLAUDE_PLUGIN_ROOT}/scripts/llm-review.mjs" config-set --provider gemini --transport cli
Re-run the Step 1 probe. If cli.login indicates a login is still required (it is not the "already authenticated" note), tell the user to authenticate themselves in this session by typing: !{cli.login} — this is an interactive browser/login you cannot perform for them.
Present the final probe output.

API KEY FLOW:

Tell the user where to get a key: api.keyHelp.
Offer how to provide it, most secure first:
- Recommended: run /plugin, open llm-review config, paste the key into the secure prompt (stored in the OS keychain).
- Or export api.primaryEnv in their shell for this session.
- Advanced — the user runs this in their own terminal (never you): printf %s 'THE_KEY' | node "${CLAUDE_PLUGIN_ROOT}/scripts/llm-review.mjs" config-set --provider gemini --transport api --api-key-stdin (key via stdin, never in argv; writes ~/.config/llm-review/config.json, chmod 600).
Security — hard rule: never run any command containing the literal key yourself; a crafted key can inject shell commands. If the user pasted a key into the chat, do NOT put it in a command — tell them it is now exposed, to add it via the keychain (/plugin) or their own shell env, and to rotate it.
Re-run the Step 1 probe and present it.

Step 4 — finish: state whether the provider is now ready and show the exact review command (reviewCommand, e.g. /llm-review:gemini). Use AskUserQuestion at most twice total in this whole flow.

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.
