Agent skill
gemini-system
Gemini CLI leverages 1M context for three roles: codebase analysis, external research (Google Search grounding), and multimodal file reading. MUST use when PDF, video, audio, or image files need content extraction. Also use for large-scale codebase understanding and external research/survey. Auto-triggers: file extensions .pdf, .mp4, .mov, .mp3, .wav, .m4a. Planning/design → use Codex instead.

SKILL.md
Gemini System — Analysis, Research & Multimodal
Gemini CLI は 1M context を活用し、大規模分析・リサーチ・マルチモーダル読取を担当する。
詳細ルール:
.claude/rules/gemini-delegation.md
Gemini の3つの役割
1. コードベース・リポジトリ理解
Gemini の 1M context でプロジェクト全体を分析する（Claude の 200K では収まらない場合）。
# プロジェクト構造の分析
gemini -p "Analyze this codebase: directory structure, key modules, patterns, dependencies, and architecture" 2>/dev/null
# 特定ファイルの詳細分析
gemini -p "Analyze this code: purpose, patterns, dependencies" < /path/to/file 2>/dev/null
2. 外部リサーチ・サーベイ
Gemini の Google Search grounding で最新情報を調査する。
# ライブラリ調査
gemini -p "Research: {library}. Latest version, features, constraints, best practices, pitfalls" 2>/dev/null
# ベストプラクティス調査
gemini -p "Research best practices for {topic}. Latest recommendations, patterns, anti-patterns" 2>/dev/null
# 技術比較
gemini -p "Compare {A} vs {B} for {use case}. Pros, cons, performance, community" 2>/dev/null
3. マルチモーダルファイル読取
PDF、動画、音声、画像ファイルの内容を抽出する。
# 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
| 対象 | 拡張子 |
|---|---|
.pdf |
|
| 動画 | .mp4, .mov, .avi, .mkv, .webm |
| 音声 | .mp3, .wav, .m4a, .flac, .ogg |
| 画像（高度分析） | .png, .jpg, .jpeg, .gif, .webp, .svg |
スクリーンショットの単純確認は Claude の Read ツールで直接可能。
Auto-Trigger（自動発動）
マルチモーダルファイルがタスクに登場した時点で、ユーザー指示を待たず自動で Gemini に渡す。
Gemini を使わないこと
| タスク | 正しい担当 |

| 設計・計画 | Codex |
| デバッグ | Codex |
| コード実装 | Claude / サブエージェント |
How to Use
Subagent Pattern（出力が大きい場合）
Task tool parameters:
- subagent_type: "gemini-explore"
- prompt: |
{task description}
gemini -p "{prompt}" 2>/dev/null
Save results to .claude/docs/research/{topic}.md
Return CONCISE summary (5-7 bullet points).
Direct Call（短い抽出の場合）
gemini -p "{what to extract/research}" 2>/dev/null
Language Protocol
- Ask Gemini in English
- Receive response in English
- Report to user in Japanese
