Execute Button States Documentation

Overview

The Execute Button is a key component of MVP3 Sprint 2 that enables users to trigger simulated execution of their planned steps. This document describes the various states and behaviors of the execute button.

Button States

1. Initial State (Hidden)

• Visibility: visible=False
• Condition: When no action plan has been generated
• Behavior: Button is not displayed to the user
• CSS Classes: execute-button (when visible)

2. Ready State (Visible & Enabled)

• Visibility: visible=True
• Condition: When valid action plan exists and input fields are properly filled
• Text: "🚀 Execute Plan (Simulated)"
• Variant: primary (green gradient styling)
• Behavior: Clickable and ready for execution
• Visual: Green gradient background with hover effects

3. Executing State (Disabled)

• Visibility: visible=True
• Condition: During execution processing
• Text: "⏳ Executing..." (would be implemented in future enhancement)
• Behavior: Disabled to prevent multiple simultaneous executions
• Visual: Loading indicator or spinner (future enhancement)

4. Success State (Temporary)

• Visibility: visible=True
• Condition: After successful execution completion
• Text: "✅ Execution Complete" (would be implemented in future enhancement)
• Behavior: Brief success indication before returning to ready state
• Visual: Success styling (future enhancement)

5. Error State (Temporary)

• Visibility: visible=True
• Condition: After execution error
• Text: "❌ Execution Failed" (would be implemented in future enhancement)
• Behavior: Brief error indication before returning to ready state
• Visual: Error styling (future enhancement)

Button Behavior

Visibility Control

The execute button visibility is controlled by the handle_find_tools function:

• Hidden by default when no action plan exists
• Shown when a valid action plan is generated
• Remains visible throughout the input filling process

Click Handler

The button is wired to the handle_execute_plan function with the following inputs:

• query_input: Original user query
• *prompt_input_fields: All dynamic input field values

State Management

Current implementation includes:

• ✅ Visibility toggle: Based on action plan availability
• ✅ Click prevention: Through proper event handling
• ✅ Error handling: Graceful error display in results
• ⏳ Loading states: Planned for future enhancement
• ⏳ Visual feedback: Planned for future enhancement

CSS Styling

Base Styling

.execute-button {
    background: linear-gradient(135deg, #28a745 0%, #20c997 100%);
    margin-top: 16px;
}

Hover Effects

The button inherits hover effects from the general button styling:

• Slight upward translation (transform: translateY(-1px))
• Enhanced shadow for depth
• Smooth transitions

Integration Points

With Input Fields

• Button appears after input fields are generated
• Button state should reflect input validation (future enhancement)
• Button collects all input field values on click

With Results Display

• Execution results are displayed in execution_output_display component
• Results include comprehensive execution information
• Error messages are displayed in the same area

With Agent System

• Button triggers the StubExecutorAgent through handle_execute_plan
• Integrates with the planner to re-generate current plan
• Handles agent availability gracefully

Future Enhancements

Planned Improvements

1. Real-time Input Validation: Enable/disable based on input completeness
2. Loading States: Visual feedback during execution
3. Progress Indicators: Show execution progress
4. State Animations: Smooth transitions between states
5. Keyboard Shortcuts: Enable execution via keyboard
6. Confirmation Dialogs: For complex or destructive operations

Technical Considerations

• Button state should be reactive to input changes
• Loading states should prevent UI freezing
• Error states should provide actionable feedback
• Success states should guide next steps

Testing

Test Coverage

The execute button functionality is tested in tests/test_execute_button.py:

• ✅ Handler function existence
• ✅ Valid input processing
• ✅ Error handling (empty query, missing agents, no plan)
• ✅ Multiple input handling
• ✅ Performance requirements
• ✅ Result formatting

Manual Testing

To manually test the execute button:

1. Start the application: python app.py
2. Navigate to the Gradio UI
3. Enter a query and generate an action plan
4. Fill in any required input fields
5. Click the "🚀 Execute Plan (Simulated)" button
6. Verify execution results are displayed

API Integration

Gradio Event Binding

execute_button.click(
    fn=handle_execute_plan,
    inputs=[query_input, *prompt_input_fields],
    outputs=[execution_output_display],
    api_name="execute_plan",
)

Handler Function Signature

def handle_execute_plan(original_user_query: str, *prompt_field_values: str) -> str:
    """Execute the planned step with collected user inputs using StubExecutorAgent."""

Accessibility

Current Implementation

• Semantic button element with clear labeling
• Descriptive text indicating simulated execution
• Proper focus management through Gradio

Future Accessibility Enhancements

• ARIA labels for state changes
• Screen reader announcements for execution status
• Keyboard navigation support
• High contrast mode support

This documentation covers the MVP3 Sprint 2 implementation of the Execute Button. Future sprints will enhance the button with additional states, visual feedback, and improved user experience.
