gemini-cli

Configuration instructions for using Gemini, Google's multimodal AI agent, as a coding agent. Multimodal means it can work with more than just text, such as images or other media.

In plain words
What is it for?
They help Gemini receive tickets, generate or explain code, create documentation, modify a codebase, and report completion.
Why use it?
They explain how to install the required SDK, set an API key, configure the agent, and understand its experimental limitations.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 9 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 315 The whole file, excluding the scripts and references it only reads on demand.

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-cli 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 yesterday.

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 is Google's multimodal agent CLI with strong coding capabilities.

Status

Gemini integration is currently experimental. Features may be limited compared to other agents.

Installation

Install the Google AI SDK:

pip install google-generativeai

Plans and Pricing

Configuration

See the full Gemini agent configuration reference.

Add Gemini to your Operator configuration:

# ~/.config/operator/config.toml

[agents.gemini]
enabled = true
api_key_env = "GOOGLE_AI_API_KEY"
model = "gemini-pro"

Authentication

Set your Google AI API key:

export GOOGLE_AI_API_KEY="your-api-key"

Get an API key from Google AI Studio.

Features

Gemini provides:

  • Code generation and completion
  • Multi-language support
  • Code explanation
  • Documentation generation

Limitations

Current experimental limitations:

  • Limited context window compared to Claude
  • May require more specific prompting
  • Some Operator features may not be fully supported

Operator Integration

When Operator assigns a ticket to Gemini:

  1. Gemini receives the ticket context
  2. Generates code implementations
  3. Applies changes to the codebase
  4. Reports completion status
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.

gemini-cli is an agent published in the GitHub repository untra/operator (36 stars, last pushed 4d ago), licensed MIT. It adds 9 tokens to every session and 315 once invoked, about $0.0000 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 2026-08-30.
