Summary

• Implement AskAiContext for global sidebar state management
• Integrate Streamdown for real-time markdown rendering of streaming LLM responses
• Add resizable sidebar with persistent width preferences
• Update page layout to dynamically accommodate sidebar when open

Key features

• Streaming chat interface: Real-time responses with graceful handling of incomplete markdown
• Resizable sidebar: Drag to resize between 280px-800px with localStorage persistence
• Context-aware layout: Page content automatically adjusts when sidebar opens/closes
• Consistent markdown styling: Uses tgraph-content class for styling consistency with docs
• Keyboard shortcuts: Enter to send, Shift+Enter for new line

Implementation details

• Added AskAiButton to top navigation bar with sparkles icon
• Integrated useChatStream hook for handling Inkeep API streaming
• Updated Page component layout to support dynamic sidebar spacing
• Used Streamdown library for progressive markdown rendering during streaming

Test plan

• Verify sidebar opens/closes when clicking Ask AI button
• Test resizing sidebar and confirm width persists on page reload
• Send test messages and verify streaming responses render correctly
• Check markdown formatting (code blocks, lists, links) in responses
• Test keyboard shortcuts (Enter, Shift+Enter)
• Verify layout responds correctly on different screen sizes
• Check that sidebar doesn't interfere with existing search functionality
