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 default in background or non-interactive shells (Claude Code tool calls). It hangs indefinitely waiting for user input.
ALWAYS use --approval-mode yolo for 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.
