description	All-purpose Gemini 3 Pro client with Thinking enabled. Query, analyze files (MP4, PDF, images), YouTube videos, generate/edit images. Uses browser cookies - no API key required.

Gemini 3 Pro Assistant Provide access to Gemini 3 Pro with Thinking for queries, file analysis, and image generation A comprehensive Gemini 3 Pro skill using gemini-webapi for cookie-based authentication. Supports text queries, file analysis (video, PDF, images), YouTube analysis, and image generation/editing. Uses "Thinking with 3 Pro" mode by default for enhanced reasoning. General questions with Thinking enabled for complex reasoning Upload MP4 files for summarization, timestamp finding, content extraction Pass YouTube URLs for video understanding via extension Upload PDFs and documents for summarization and Q&A Upload images for description, OCR, analysis Create images from text prompts Modify existing images with natural language Automatic web search for current information View model's reasoning process with --show-thoughts

Chrome browser logged into gemini.google.com First time setup: cd ~/.claude/skills/gemini && python3 -m venv .venv && source .venv/bin/activate && pip install -r requirements.txt On macOS, allow Keychain access when prompted (first run)

Text query: ```bash ~/.claude/skills/gemini/webapi "Explain quantum computing" ```

Analyze video file:
```bash
~/.claude/skills/gemini/webapi "Summarize this video" --file video.mp4
```

Analyze YouTube video:
```bash
~/.claude/skills/gemini/webapi "What are the key points?" --youtube "https://youtube.com/watch?v=..."
```

Analyze document:
```bash
~/.claude/skills/gemini/webapi "Summarize this report" --file report.pdf
```

Generate image:
```bash
~/.claude/skills/gemini/webapi "A sunset over mountains" --generate-image sunset.png
```

Edit image:
```bash
~/.claude/skills/gemini/webapi "Make the sky purple" --edit photo.jpg --output edited.png
```

Show thinking process:
```bash
~/.claude/skills/gemini/webapi "Solve step by step: What is 15% of 240?" --show-thoughts
```

| Option | Description | |--------|-------------| | `--file, -f FILE` | Input file (MP4, PDF, PNG, JPG, etc.) | | `--youtube URL` | YouTube video URL to analyze | | `--generate-image FILE` | Generate image and save to FILE | | `--edit IMAGE` | Edit existing image (use with --output) | | `--output, -o FILE` | Output file path for image operations | | `--aspect RATIO` | Aspect ratio for images (16:9, 1:1, 4:3, 3:4) | | `--show-thoughts` | Display model's thinking process | | `--model MODEL` | Model to use (default: gemini-3.0-pro) | | `--json` | Output response as JSON | | `--retries N` | Number of retries for transient failures (default: 3) | | `--timeout SECS` | Client initialization timeout in seconds (default: 120) | | `--help, -h` | Show help | The client includes several reliability improvements: - **Retry with backoff**: Transient errors (timeouts, rate limits, 5xx) trigger automatic retries with exponential backoff - **Response stability checks**: Image generation waits for stable response before saving - **Extended timeouts**: Video file analysis automatically uses longer timeouts (180s) - **Detailed diagnostics**: Error messages include troubleshooting suggestions 1. User requests analysis, generation, or query 2. Determine appropriate mode (query, file analysis, image gen) 3. Construct command with appropriate flags 4. Run webapi script 5. Process and present results ```bash ~/.claude/skills/gemini/webapi "What are the implications of quantum computing for cryptography? Think through this carefully." --show-thoughts ```

Cookie or initialization errors, repeated init failures 1. Ensure you're logged into gemini.google.com in Chrome 2. On macOS, allow Keychain access when prompted 3. Try closing Chrome completely and reopening gemini.google.com 4. Clear Chrome cookies for gemini.google.com and re-login 5. Try increasing --timeout if failures are intermittent

<issue name="Transient/timeout errors">
  <symptom>Timeout, connection reset, or 5xx errors</symptom>
  <solution>The client automatically retries with backoff. If failures persist, try --retries 5 or --timeout 180. Check your network connection.</solution>
</issue>

<issue name="No images generated">
  <symptom>Script runs but no image output after retries</symptom>
  <solution>
    1. Rephrase prompt to be more explicit about wanting an image
    2. Some content may be filtered by safety systems
    3. Try simpler prompts first to verify the client works
    4. Check if the model returned text (may indicate why image failed)
  </solution>
</issue>

<issue name="Module not found">
  <symptom>ImportError for gemini_webapi</symptom>
  <solution>Run: cd ~/.claude/skills/gemini && source .venv/bin/activate && pip install -r requirements.txt</solution>
</issue>

<issue name="YouTube not working">
  <symptom>Cannot analyze YouTube video</symptom>
  <solution>Ensure YouTube extension is enabled in your Gemini web settings at gemini.google.com</solution>
</issue>

<issue name="No thinking shown">
  <symptom>--show-thoughts returns nothing</symptom>
  <solution>Thinking may be skipped for trivial queries. Try a more complex question, or the model may have used code execution instead.</solution>
</issue>

<issue name="Rate limiting">
  <symptom>Repeated failures with rate limit errors</symptom>
  <solution>Wait a few minutes before retrying. Consider spacing out requests. The client uses exponential backoff automatically.</solution>
</issue>

Always uses "Thinking with 3 Pro" mode for enhanced reasoning Google Search grounding is automatic - just ask about current events YouTube extension must be enabled in gemini.google.com settings Cookie-based auth - no API key needed, uses your Google account quota First run on macOS prompts for Keychain access
