Trello 项目看板自动化管理

I have a 5-page PRD document at ~/docs/feature-prd.pdf. Please:

1. Read and analyze the PRD
2. Break it down into tasks for my Trello board "Product Development"
3. Create cards in the "To Do" list with:
   - Clear task titles
   - Detailed descriptions
   - Appropriate labels (frontend, backend, design, etc.)
   - Due dates based on priority
4. Add a checklist to each card for subtasks
5. Give me a summary of created cards
