Gemini System — Multimodal File Processing

Gemini CLI is specialized for multimodal file processing (PDF, video, audio, image).

Detailed rules: .claude/rules/gemini-delegation.md Research/codebase analysis: Use general-purpose subagent (Opus) instead — Opus now supports 1M context.

Multimodal File Processing

Extract content from PDF, video, audio, and image files.

# PDF
gemini -p "Extract: {what to extract}" < /path/to/file.pdf 2>/dev/null

# Video
gemini -p "Summarize: key concepts, timestamps" < /path/to/video.mp4 2>/dev/null

# Audio
gemini -p "Transcribe and summarize: decisions, action items" < /path/to/audio.mp3 2>/dev/null

# Image (diagrams, charts)
gemini -p "Analyze: components, relationships, data flow" < /path/to/diagram.png 2>/dev/null

Simple screenshot inspection can be done directly with Claude's Read tool.

Auto-Trigger

When multimodal files appear in a task, automatically pass them to Gemini without waiting for user instructions.

How to Use

Subagent Pattern (for large outputs)

Task tool parameters:
- subagent_type: "gemini-explore"
- prompt: |
    {task description}

    gemini -p "{prompt}" < /path/to/file 2>/dev/null

    Return CONCISE summary (5-7 bullet points).

Direct Call (for short extractions)

gemini -p "{what to extract}" < /path/to/file 2>/dev/null
