gemini

gemini is a skill for Claude Code, Codex from the-open-agent/openagent. It costs 17 tokens per session (169 once invoked), scanned A, original, Apache-2.0.

Instructions for using the Gemini command-line program to ask questions, create summaries, generate output, and manage extensions. A command-line program is a tool operated by typing commands in a terminal.

In plain words
What is it for?
Use it for one-shot questions, summaries, generated responses, structured JSON output, and listing or managing Gemini extensions.
Why use it?
It gives an agent a consistent way to run Gemini for one request at a time and return results in text or JSON. It also explains the basic authentication and extension commands.

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 4d 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

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.

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.
