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 | $0.01091 | $0.01091 |
| Opus 5 | $0.00545 | $0.00545 |
| Sonnet 5 | $0.00218 | $0.00218 |
| Haiku 4.5 | $0.00109 | $0.00109 |
Grade A, and why
gemini-claude-plugin GEMINI.md 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Gemini plugin — how to use it
The google-gemini plugin (/gemini:* slash commands) lets you delegate work to Gemini CLI from inside Claude Code. Three entry points cover three distinct shapes of work.
Pick the entry point first
| You want… | Use |
|---|---|
| Read-only diagnosis or a single-shot research answer | /gemini:rescue |
| Passive observation of a long-running Gemini job (events stream back) | /gemini:rescue-stream |
| Autonomous execution of a planned subtask, with self-healing + structured handoff | /gemini:execute |
| Plain "review my diff" | /gemini:review |
| Review with steering / adversarial questions | /gemini:adversarial-review <focus> |
| Background job control | /gemini:status · /gemini:result · /gemini:cancel |
| Verify install + auth | /gemini:setup |
Three rules that prevent misroutes
/gemini:rescueis read-only by default. It runs Gemini under--approval-mode plan. If the user wants Gemini to actually change files, that is/gemini:execute, notrescue --yolo(don't reach for the rescue with a yolo flag — execute is the right shape and carries the executor envelope)./gemini:executeis write-capable and autonomous by default (--yolo --sandbox, background+stream). Don't use it for review (that's/gemini:reviewor/gemini:adversarial-review) or research (that's/gemini:rescue). Don't use it without a real plan; vague asks produce vague execution.- Foreground vs background:
/gemini:rescuedefaults to foreground; add--backgroundfor unclear-scope investigations./gemini:executedefaults to background+stream; add--waitonly for tight, bounded tasks./gemini:rescue-streamis always streamed.
Don't touch unless explicitly asked
--model— leave unset. Gemini picks its own default.--yolo(rescue only) — only when the user explicitly wants writes via rescue. Prefer/gemini:executeinstead.--no-sandbox(execute only) — only when the task genuinely needs host access (rare).
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.

gemini-claude-plugin GEMINI.md is an instructions file published in the GitHub repository madciapka/gemini-claude-plugin (8 stars, last pushed 4mo ago), licensed MIT. It adds 1,091 tokens to every session, about $0.0055 per session on Opus 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.
