Special tags modify how Agentastic's AI processes your requests. These system-level commands control display capture, model selection, and other core behaviors.
Screen Tags
The /screen tag enables AI to see and analyze content from your displays. Perfect for getting help with what's on your screen.
Basic Usage
/screen What's in this spreadsheet?
/screen Explain this error message
/screen Help me understand this diagram
Multi-Monitor Support
Specify which screen to capture:
/screen:0or/screen:active- Screen where launcher appears (default)/screen:1- Primary display/screen:2- Second monitor/screen:3- Third monitor
Examples
/screen:1 Analyze the chart on my main display
/screen:2 What's in the terminal on my second monitor
/screen:active Describe what you see
Screen Tag Tips
- Privacy First - Only enables when you use the tag
- Clear Context - AI sees exactly what you see
- Multiple Screens - Great for comparing displays
- Error Handling - Gracefully handles invalid screen numbers
Common Use Cases
- Debugging code - "What's wrong with this function?"
- Understanding UIs - "How do I use this application?"
- Reading content - "Summarize this article"
- Data analysis - "What patterns do you see in this data?"
Image Paste
You can now paste images directly into the launcher for visual analysis, without needing to enable screen capture.
How It Works
- Copy any image - From screenshots, web browsers, image editors, etc.
- Paste with Cmd+V - The image appears as
[📎 image.png]in your text - Ask your question - Type normally around the placeholder
- Send to AI - Press Enter to include the image with your prompt
Examples
# Analyze a screenshot
[Paste image] "What's the error in this screenshot?" [📎 image.png]
# Understand a diagram
[Paste image] "Explain this architecture diagram" [📎 image.png]
# Extract text from images
[Paste image] "What text is in this image?" [📎 image.png]
# Get help with UI
[Paste image] "How do I fix this layout issue?" [📎 image.png]
Key Features
- Visual indicator -
[📎 image.png]shows an image is attached - Automatic handling - Placeholder removed when sending
- Regular paste works - Cmd+V still pastes text when no image in clipboard
- One image at a time - New paste replaces previous image
Image Paste vs Screen Capture
| Feature | Image Paste | Screen Capture (/screen) |
|---|---|---|
| Activation | Cmd+V with image | /screen tag or Cmd+2 |
| Source | Clipboard | Live display |
| Privacy | Only shared image | Entire screen |
| Use Case | Specific images | Current screen content |
Model Tags
The /model tag lets you choose which AI model processes your request. Different models offer different trade-offs between speed and capability.
Available Models
Fast Model (/model:fast)
- Response time: <1 second
- Best for: Quick questions, simple tasks
- Token limit: Moderate
- Cost: Lowest
Smart Model (/model:smart)
- Response time: 1-2 seconds
- Best for: General purpose, balanced performance
- Token limit: Higher
- Cost: Moderate
Genius Model (/model:genius)
- Response time: 2-5 seconds
- Best for: Complex reasoning, creative tasks
- Token limit: Highest
- Cost: Premium
Model Selection Examples
/model:fast Quick grammar check
/model:smart Write a professional email
/model:genius Analyze this complex legal document
Automatic Model Selection
Without a /model tag, Agentastic automatically selects based on:
- Prompt complexity
- Task requirements
- Response time preferences
- Cost settings
Model Comparison
| Feature | Fast | Smart | Genius |
|---|---|---|---|
| Speed | ⚡⚡⚡ | ⚡⚡ | ⚡ |
| Accuracy | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ |
| Creativity | ⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ |
| Context Length | 4K | 16K | 32K |
| Best For | Quick tasks | General use | Complex work |
Vision Tags
The /vision tag is a shorthand for enabling visual analysis, similar to the eye icon in the launcher.

Best Practices
Screen Tags
- Specify screen numbers for multi-monitor setups
- Use
:activefor flexibility - Remember privacy - only capture what's needed
- Combine with specific questions
Model Tags
- Start with fast for simple tasks
- Upgrade to genius for complex work
- Consider cost/speed trade-offs
- Let auto-selection work when unsure
Format Tags
- Match format to destination
- Use markdown for rich content
- JSON for structured data
- Plain for maximum compatibility
Performance Considerations
Screen Capture Impact
- First capture: 100-200ms
- Subsequent captures: 50ms (cached)
- Large screens: May increase processing time
- Multiple screens: Parallel capture when possible
Model Performance
- Fast: Optimized for speed
- Smart: Balanced caching
- Genius: May queue during peak times
Troubleshooting
Tags Not Working
- Check spelling exactly
- Ensure proper format
/tag:option - Verify permissions granted
- Update to latest version
Slow Performance
- Use appropriate model for task
- Disable vision if not needed
- Specify single screen instead of all
- Clear cache if issues persist
Next Steps
- Explore Tool Tags for productivity features
- Learn about /agent and /search
