+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+The Drawfast tool has been temporarily disabled due to output issues that need debugging.
+
+## Background
+Drawfast is a real-time AI image generation tool that generates images as users draw. The tool has been disabled in Board.tsx pending debugging.
+
+## Files to investigate
+- `src/shapes/DrawfastShapeUtil.tsx` - Shape rendering and state
+- `src/tools/DrawfastTool.ts` - Tool interaction logic
+- `src/hooks/useLiveImage.tsx` - Live image generation hook
+
+## To re-enable
+1. Uncomment imports in Board.tsx (lines 50-52)
+2. Uncomment DrawfastShape in customShapeUtils array (line 173)
+3. Uncomment DrawfastTool in customTools array (line 199)
+<!-- SECTION:DESCRIPTION:END -->
