Vision Control Skill

Vision Control Skill

Control the user's computer through visual understanding with mouse and keyboard simulation.

Core Workflow

1. Capture screen with grid overlay - Take screenshot with coordinate grid
2. Analyze visual content - Determine what needs to be clicked
3. Identify target coordinates - Find grid cell containing the target
4. Execute click - Perform mouse click at the specified location

Scripts

capture_grid.py

Captures a screenshot with grid overlay. By default, saves to a temporary file with automatic timestamping. Optionally accepts a custom output path.

python scripts/capture_grid.py [output_path]

Examples:

python scripts/capture_grid.py                    # Auto-saves to temp directory
python scripts/capture_grid.py screen_grid.png    # Save to specific path

Use this to get a visual representation of the screen with coordinate labels.

click_location.py

Performs mouse clicks at the specified grid coordinate. Supports left-click, right-click, and double-click. Automatically captures a screenshot, performs the action, and cleans up the temporary screenshot file.

python scripts/click_location.py <grid_command> [--action ACTION] [--keep]

Examples:

python scripts/click_location.py S3                    # Left click
python scripts/click_location.py S3/2 --action right   # Right click at quadrant
python scripts/click_location.py A1 --action double    # Double click
python scripts/click_location.py M5 --keep             # Click and keep screenshot

Grid format: [COLUMN][ROW] or [COLUMN][ROW]/[QUADRANT]

• Columns: A-Z (left to right)
• Rows: 1-15 (top to bottom)
• Quadrants: 1=top-left, 2=top-right, 3=bottom-left, 4=bottom-right

Options:

• --action click|right|double: Mouse action type (default: click)
• --keep: Preserve the screenshot file instead of auto-deleting (useful for debugging)

mouse_action.py

Comprehensive mouse control script supporting all mouse actions: click, right-click, double-click, move, drag, and scroll.

python scripts/mouse_action.py <action> <args...> [--keep]

Actions:

• click <grid> - Left click at grid location
• right <grid> - Right click at grid location
• double <grid> - Double click at grid location
• move <grid> - Move cursor to grid location (no click)
• drag <from> <to> - Drag from one grid to another
• scroll <grid> <amount> - Scroll at grid location (positive=up, negative=down)

Examples:

python scripts/mouse_action.py click S3        # Left click
python scripts/mouse_action.py right S3/2      # Right click at quadrant
python scripts/mouse_action.py double A1       # Double click
python scripts/mouse_action.py move M8         # Move cursor without clicking
python scripts/mouse_action.py drag S3 T5      # Drag from S3 to T5
python scripts/mouse_action.py scroll M8 5     # Scroll up 5 units
python scripts/mouse_action.py scroll M8 -3    # Scroll down 3 units

keyboard_input.py

Comprehensive keyboard control script supporting text typing, key presses, and keyboard shortcuts.

python scripts/keyboard_input.py <action> <args...>

Actions:

• type <text> - Type text at current cursor position
• press <key> - Press a single key (enter, tab, esc, etc.)
• hotkey <key1+key2+...> - Press keyboard shortcut
• click-type <grid> <text> - Click at grid location then type text

Examples:

python scripts/keyboard_input.py type "Hello World"
python scripts/keyboard_input.py press enter
python scripts/keyboard_input.py press tab
python scripts/keyboard_input.py hotkey ctrl+c
python scripts/keyboard_input.py hotkey ctrl+shift+v
python scripts/keyboard_input.py click-type M8 "search query"

Common keys: enter, tab, esc, space, backspace, delete, up, down, left, right, home, end, pageup, pagedown, f1-f12

vision_control_core.py

Mouse Methods:

• click_at_grid(command, button='left', clicks=1) - Click at grid location
• right_click_at_grid(command) - Right click at grid location
• double_click_at_grid(command) - Double click at grid location
• move_to_grid(command, duration=0.5) - Move cursor to grid location
• drag_to_grid(from_command, to_command, duration=1.0) - Drag between locations
• scroll_at_grid(command, amount) - Scroll at grid location

Keyboard Methods:

• type_text(text, interval=0.0) - Type text at current position

• cleanup_screenshot() - Clean up temporary screenshot

Can be imported for custom workflows.

Typical Usage Patterns

Basic Click

When a user asks to click something on their screen:

1. Run capture_grid.py to get a screenshot with grid overlay (saved to temp directory)
2. Present the image to analyze where the target element is located
3. Identify the grid cell (e.g., "S3") or cell with quadrant (e.g., "S3/2")
4. Run click_location.py or mouse_action.py with the identified coordinate
5. Confirm the action was successful

Right-Click Menu

When a user needs to open a context menu:

1. Capture screen with capture_grid.py
2. Identify the target location
3. Run mouse_action.py right <grid> to right-click

Drag and Drop

When a user needs to drag something:

1. Capture screen with capture_grid.py
2. Identify source and target locations
3. Run mouse_action.py drag <from> <to>

Scrolling

When a user needs to scroll:

1. Capture screen with capture_grid.py
2. Identify where to scroll
3. Run mouse_action.py scroll <grid> <amount> (positive=up, negative=down)

Typing Text

When a user needs to type or enter text:

1. For typing at current cursor: Run keyboard_input.py type "text"
2. For filling a form field:
   • Capture screen with capture_grid.py
   • Identify the input field location
   • Run keyboard_input.py click-type <grid> "text"

Keyboard Shortcuts

When a user needs to use keyboard shortcuts:

1. Run keyboard_input.py hotkey <keys> (e.g., ctrl+c, ctrl+v, alt+tab)
2. Common shortcuts: Copy (ctrl+c), Paste (ctrl+v), Save (ctrl+s), Undo (ctrl+z)

Screenshot Management

The skill uses automatic temporary file management:

• Auto-temp storage: Screenshots are saved to the system temp directory with timestamps
• Auto-cleanup: click_location.py automatically deletes screenshots after clicking
• Privacy-friendly: No screenshot clutter on disk
• Debug mode: Use --keep flag to preserve screenshots when troubleshooting

Temp file format: vision_control_YYYYMMDD_HHMMSS_microseconds.png

Reference Documentation

• Grid System: See grid_system.md for coordinate system and quadrant layout
• Keyboard Actions: See keyboard_actions.md for comprehensive keyboard reference, key names, and shortcuts

Safety Considerations

• This skill performs actual mouse actions on the user's system
• Always confirm the target location before performing actions
• Be aware that actions may trigger immediate effects in applications
• Consider asking for user confirmation before critical or destructive actions
• Drag operations may take 1+ seconds to complete
