📄 Description

Summary

  • Added collapsible think block support for AI assistant messages
  • Supports both <think> and <details> tags for compatibility
  • Integrated seamlessly with existing StreamdownMarkdown component

Implementation Details

Components Created

  • ThinkBlockHeader: Displays thinking status with animated loading indicator, supports expand/collapse functionality
  • ThinkBlockContent: Renders think block content using Streamdown with smooth transitions

Core Features

  • Automatic detection of <think> and <details> tags at the beginning of messages
  • Real-time streaming support with "thinking" status animation
  • Auto-expands when thinking starts for better user experience
  • Smooth animations for expand/collapse transitions
  • Full internationalization support (en, zh, ja, fr, es, vi)

Technical Approach

The implementation extends the existing StreamdownMarkdown component to:

  1. Extract think block content from the message
  2. Render think blocks separately with appropriate styling
  3. Maintain streaming capabilities for both think and main content
  4. Handle incomplete/unclosed tags during streaming

Test Plan

  • Tested with <think> tags
  • Tested with <details> tags
  • Verified streaming behavior
  • Tested expand/collapse functionality
  • Verified all language translations display correctly
