Gemini CLI

Use Gemini in one-shot mode with a positional prompt (avoid interactive mode).

Quick start

• gemini "Answer this question..."
• gemini --model <name> "Prompt..."
• gemini --output-format json "Return JSON"

File-output mode (for large token or explicit file return)

• When content is large (e.g. long article/story/report) or user explicitly asks for file output, use:
• python3 /Users/shichen/skills/gemini/gemini_file_runner.py --prompt "<prompt>"
• Default model: gemini-3-flash-preview
• For video parsing with large content (long video, dense transcripts, many segments), prefer gemini-3-flash-preview first.
• Script behavior:
  • Always saves Gemini output to a file under outputs/ in this skill directory.
  • Always returns file_path (absolute path) in JSON.
  • Optionally returns content when --include-content is provided.
• Optional args:
  • --model <model_name>
  • --output-format text|json
  • --output-file <filename>
  • --output-dir <dir>
  • --include-content

Required response contract for this mode

• Must include absolute file path from script JSON: file_path
• Content in response is optional and controlled by --include-content

Example

• User request: 使用 gemini 模型写 1000 字小说并输出文件给我
• Command:
  • python3 /Users/shichen/skills/gemini/gemini_file_runner.py --prompt "写一篇约 1000 字中文小说，主题是..." --output-file novel-1000-words.txt
• Expected JSON stdout:
  • {"ok":true,"file_path":"/Users/shichen/skills/gemini/outputs/novel-1000-words.txt"}

Video parsing example (large content)

• User request: 请解析这个长视频并输出文件
• Command:
  • python3 /Users/shichen/skills/gemini/gemini_file_runner.py --model gemini-3-flash-preview --prompt "解析视频内容并输出结构化总结..." --output-file video-analysis.txt

Extensions

• List: gemini --list-extensions
• Manage: gemini extensions <command>

Notes

• If auth is required, run gemini once interactively and follow the login flow.
• Avoid --yolo for safety.
