description: Use when the user wants to use Google Gemini for analysis, large files or codebases, sandbox execution, or brainstorming. Runs headless Gemini CLI via a Node script (no MCP). Triggers on "use Gemini", "ask Gemini", "analyze with Gemini", "large file", "sandbox", "brainstorm with Gemini".

Omega Gemini CLI (headless)

This skill runs the Gemini CLI in headless mode so Antigravity can call Gemini from the project—no MCP server or MCP configuration required.

Overview

From the project root (the directory that contains .claude and .agent), run the headless script. It invokes gemini -p "..." with optional model, sandbox, and JSON flags and returns the response. Requires Node.js and Google Gemini CLI to be installed.

How to run Gemini

From the project root, run:

bash
node .claude/skills/omega-gemini-cli/scripts/ask-gemini.mjs "USER_PROMPT"

Optional flags (append to the command):

  • •--model gemini-2.5-flash (or another model) — reduce quota issues.
  • •--sandbox — sandbox mode for running code.
  • •--json — output JSON; the script prints the .response field.

Examples:

  • •Analysis: node .claude/skills/omega-gemini-cli/scripts/ask-gemini.mjs "Review @src/main.js for bugs"
  • •With model: node .claude/skills/omega-gemini-cli/scripts/ask-gemini.mjs "Summarize this" --model gemini-2.5-flash
  • •Stdin: echo "Explain recursion" | node .claude/skills/omega-gemini-cli/scripts/ask-gemini.mjs

When the user says "ask Gemini", "use Gemini", or similar, build the prompt from their request and any @ file refs, run this command from the project root, and return the script output.

When to use this skill

  • •Large files or codebases — Use Gemini's context for analysis.
  • •Second opinion / feedback — User wants Gemini's take on code or docs.
  • •Sandbox — Run or test code via Gemini (add --sandbox when supported).
  • •Brainstorming — Build a prompt that includes the challenge and optional method (e.g. SCAMPER) and run the script.

If Gemini CLI is not set up

If the script fails (e.g. "gemini not found"), direct the user to install Node.js and Gemini CLI and complete one-time auth. Setup can be verified by running from project root:

bash
node .claude/skills/omega-gemini-cli/scripts/verify-setup.mjs

Full installation and auth details: .claude/skills/omega-gemini-cli/references/installation.md and references/auth.md (same repo).

Shared scripts

Scripts are shared with the Claude and Codex skills: .claude/skills/omega-gemini-cli/scripts/. No duplicate copies are required for Antigravity.
