omega-gemini-cli

当用户希望使用Google Gemini进行分析、处理大型文件或代码库、执行沙盒环境，或进行头脑风暴时使用此功能。通过Node脚本运行无头Gemini CLI（无需MCP）。可通过“使用Gemini”“用Gemini分析”“大型文件”“沙盒”“用Gemini头脑风暴”等触发词来启动。对于不需要Gemini参与的常规代码编辑，请勿使用此功能；仅适用于那些能从Gemini的上下文理解或第二模型中获益的任务。

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". Do not use for general code edits that do not require Gemini; use for tasks that benefit from Gemini's context or a second model.

Omega Gemini CLI (headless)

This skill follows the Agent Skills open standard. Codex discovers it from REPO scope at $REPO_ROOT/.agents/skills/. It runs the Gemini CLI in headless mode so Codex can call Gemini from the project—no MCP server or MCP configuration required.

Overview

From the project root (the directory that contains .claude and .agents), 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

Input: A user prompt (and optional @ file refs). Output: The script’s stdout (Gemini’s response).

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
  1. •Build the prompt from the user’s request and any @ file refs. 2. Run the command above from the project root. 3. Return the script’s stdout to the user as Gemini’s response.

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 live in the Claude skill at .claude/skills/omega-gemini-cli/references/installation.md and references/auth.md (same repo).

Shared scripts

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