Gemini Skill
Priorities
Approval mode correctness > Model selection > Background execution safety
Goal
Execute Gemini CLI for comprehensive code review, plan analysis, or large-context processing tasks. Ask user for model selection via AskUserQuestion. Choose approval mode based on execution context (yolo for background, default for interactive terminal only). Load CLI reference for detailed command patterns, troubleshooting, and use cases.
Constraints
- NEVER use
--approval-mode defaultin background or non-interactive shells (Claude Code tool calls). It hangs indefinitely waiting for user input. - ALWAYS use
--approval-mode yolofor automated/background tasks or wrap with timeout:timeout 300 gemini ... - Ask user for model selection via AskUserQuestion before running commands.
- Requires Gemini CLI v0.16.0+ for Gemini 3 model support.
- After Gemini completes, inform user they can start a new session for follow-up analysis.
Model Selection
Ask user which model to use via AskUserQuestion:
| Model | Best for | Context window | Key features |
|---|---|---|---|
gemini-3-pro-preview | Flagship: Complex reasoning, coding, agentic tasks | 1M input / 64k output | Vibe coding, 76.2% SWE-bench, $2-4/M input |
gemini-3-flash | Sub-second latency, speed-critical applications | 1M input / 64k output | Distilled from 3 Pro, TPU-optimized |
gemini-2.5-pro | Legacy: Strong all-around performance | 1M input / 65k output | Thinking mode, mature stability |
gemini-2.5-flash | Legacy: Cost-efficient, high-volume tasks | 1M input / 65k output | Best price ($0.15/M), thinking mode |
gemini-2.5-flash-lite | Legacy: Fastest processing, high throughput | 1M input / 65k output | Maximum speed, minimal latency |
Gemini 3 Advantages: 35% higher accuracy in software engineering, state-of-the-art on SWE-bench (76.2%), knowledge cutoff January 2025.
