+# Phase 10 Plan 01: Node Autosizing Summary
+
+**Generate nodes auto-resize to match output image/video aspect ratio with constrained dimensions (200-500px width, 200-600px height)**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-01-12T00:53:24Z
+- **Completed:** 2026-01-12T00:55:46Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- Created node dimension calculation utility with image/video dimension extraction
+- GenerateImageNode auto-resizes when output image is set
+- GenerateVideoNode auto-resizes when output video is set
+- Aspect ratio maintained within size constraints
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create node dimension calculation utility** - `b0d0a4c` (feat)
+2. **Task 2: Auto-resize generate nodes on output** - `52efbea` (feat)
+
+## Files Created/Modified
+- `src/utils/nodeDimensions.ts` - Utility for image/video dimension extraction and node size calculation
+- `src/components/nodes/GenerateImageNode.tsx` - Added auto-resize effect on outputImage change
+- `src/components/nodes/GenerateVideoNode.tsx` - Added auto-resize effect on outputVideo change
+
+## Decisions Made
+- Node sizing constraints: min 200px, max 500px width; min 200px, max 600px height
+- Account for ~100px node chrome (header ~40px, controls ~60px)
+- Use requestAnimationFrame to avoid React Flow update conflicts during resize
+- Track previous output value to prevent redundant resize operations
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None
+
+## Next Phase Readiness
+- Phase 10 complete with 1/1 plans finished
+- Node autosizing working for both image and video generation nodes
+- Ready for Phase 11: UI Polish
