gemini

gemini is a skill for Claude Code, Codex from spinabot/brigade. It costs 17 tokens per session (232 once invoked), scanned A, a copy of gemini, MIT.

Instructions for using the Gemini command-line tool for one-off questions, summaries, and generated content. A command-line tool is a program run from a terminal.

In plain words
What is it for?
Use it for short Q&A, summarization, or generation tasks from the terminal, including requests that need structured JSON output.
Why use it?
It provides a consistent way to send a prompt to Gemini, choose a model, request JSON output, and handle sign-in when needed.

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

gemini 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 3d 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.

Origin

This is a copy

81% identical to gemini — 17 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Gemini CLI

Use Gemini in one-shot mode with a positional prompt (avoid interactive mode).

Quick start

  • gemini "Answer this question..."
  • gemini --model <name> "Prompt..."
  • gemini --output-format json "Return JSON"

Extensions

  • List: gemini --list-extensions
  • Manage: gemini extensions <command>

Notes

  • If auth is required, run gemini once interactively and follow the login flow.
  • Avoid --yolo for safety.
Changes

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.
