+### Tool Caching and Status Monitoring
+
+<div style="padding: 20px; background: #f0f7ff; border-radius: 8px; border-left: 4px solid #3498db; margin-top: 20px;">
+The DeepSeek Wrapper includes an advanced tool caching and status monitoring system that enhances performance and provides comprehensive visibility into the tool ecosystem.
+
+Key features of the tool caching system:
+- **Intelligent caching**: Automatically caches tool results based on input parameters
+- **Configurable TTL**: Time-to-live settings define how long cached results remain valid
+- **Cache statistics**: Detailed hit/miss metrics for performance monitoring
+- **Automatic cleanup**: Expired cache entries are automatically removed
+- **Manual control**: Clear individual or all tool caches directly from the UI
+
+The status monitoring system provides:
+- **Real-time tool status**: See which tools are ready, in error state, or not configured
+- **API key validation**: Automatic checking of API key validity
+- **Usage monitoring**: Track when tools were last used
+- **Cache visibility**: View cache size and performance metrics for each tool
+- **Visual indicators**: Color-coded status badges show tool health at a glance
+
+This comprehensive monitoring and caching system improves both performance and reliability:
+- **Reduced API costs**: Fewer redundant API calls to external services
+- **Faster responses**: Cached results return instantly without external API calls
+- **Rate limit protection**: Minimizes chances of hitting API rate limits
+- **Better debugging**: Clear visibility into tool status helps troubleshoot issues
+- **Enhanced reliability**: Retries and error handling improve overall stability
+
+The entire system is accessible through an intuitive UI panel, allowing non-technical users to monitor and manage tool performance without developer assistance.

+#### Tool Status and Caching
+
+The DeepSeek Wrapper includes a comprehensive tool status monitoring system and caching mechanism. These features enhance performance and provide better visibility into the tool system:
+
+1. **Tool Status Panel**: The Tools tab includes a status panel showing:
+   - Ready, error, and unconfigured tool counts
+   - Detailed status for each registered tool
+   - API key validation status
+   - Last usage information
+
+2. **Caching System**: Tools use an intelligent caching system to improve performance:
+   - Reduces redundant API calls for identical requests
+   - Configurable cache time-to-live (TTL) settings
+   - Cache hit/miss statistics for performance monitoring
+   - Automatic cleanup of expired cache entries
+
+![Tool Status Panel](images/tool-status-panel.png)
+
+The caching system provides several benefits:
+- Faster response times for repeated queries
+- Reduced API usage and associated costs
+- Less network traffic and lower latency
+- Protection against rate limiting on external APIs
+
+##### Managing Tool Caches
+
+You can manage the tool caching system directly from the UI:
+
+1. **View Cache Statistics**: See cache size, hit ratios, and history for each tool
+2. **Clear Individual Caches**: Each tool has a dedicated cache clear button
+3. **Clear All Caches**: Use the "Clear Tool Caches" button to reset all caches at once
+4. **Refresh Tool Status**: Update the status display to see the latest information
+
+> **Note**: Clearing the cache doesn't impact tool functionality but may result in slightly slower responses until the cache is rebuilt with new requests.
+
+##### Cache Settings
+
+The caching system uses these default settings:
+
+| Setting | Default Value | Description |
+|---------|---------------|-------------|
+| Cache Enabled | Yes | Whether caching is active for each tool |
+| Time-to-Live (TTL) | 300 seconds | How long cached results remain valid |
+| Cache Key | Request parameters | What determines a cache hit/miss |
+
+These settings provide an optimal balance between performance and freshness of information for most use cases.
