self-command GEMINI.md

Instructions for a Gemini CLI extension that lets the agent control its interface through tmux, a terminal multiplexer. It covers sending commands, waiting for tasks, and watching log files.

In plain words
What is it for?
Sending Gemini CLI commands, waiting for scheduled wake-ups, monitoring files, and managing the agent's terminal workspace.
Why use it?
It gives the agent a defined way to operate Gemini CLI and monitor longer-running work from the terminal.

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.

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

self-command 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 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.

Self Command Extension

This extension provides tools that allow the Gemini CLI agent to control its own interface via tmux, wait for tasks, monitor files, and manage the workspace.

Tools

1. self_command

Executes a Gemini CLI command programmatically.

Usage

Use this tool when you need to execute a Gemini CLI command, such as running a specific /command, listing files, or triggering other agent actions.

Tool Signature

self_command({
  command: string; // The command to send to Gemini (e.g., "/compress", "/help").
});

Response Returns a text message confirming the task has started, including a unique Request ID (e.g., [A1B2]). This ID will also appear in the completion notification.

Example

// To ask for help
self_command({ command: "/help" });

CRITICAL INSTRUCTION You MUST yield your turn immediately after calling this tool. Do not attempt to perform other actions.


2. gemini_sleep

Sleeps for a specified duration and then sends a wake-up notification.

Usage

Use this tool to pause execution while waiting for a task that you know will take a specific amount of time.

Single Active Sleep Policy: Only ONE sleep task can be active at a time. If you request a new sleep while one is already running, the system will choose the shorter duration:

  • If the new sleep ends sooner than the current one, the current sleep is cancelled and replaced by the new, shorter one.
  • If the new sleep ends later, the request is ignored, and the existing shorter sleep continues.

Recurring Sleep: You can set recurring: true to be woken up periodically (e.g., for monitoring).

  • Constraint: Recurring sleep requires a minimum interval of 3600 seconds (1 hour).

Tool Signature

gemini_sleep({
  seconds: number; // Number of seconds to sleep (or interval if recurring).
  recurring?: boolean; // Optional: If true, wakes repeatedly. Min 3600s.
});

CRITICAL INSTRUCTION You MUST yield your turn immediately after calling this tool.

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.
