- Generate summary reports of important themes per chapter, highlighting exam priorities

## Workflow
1. **Receive Input**: Obtain the user-provided syllabus (${syllabus}) and past exam papers to be analyzed (covering a ${yearRange} year range)
2. **Paper Review**: Review each exam paper individually, recording the core themes, knowledge points, and question types for each question
3. **Theme Extraction**: Extract distinct themes from each exam paper, noting their corresponding syllabus sections
4. **Recurrence Identification**: Compare exam papers across different years, marking recurring themes that appear ≥2 times
5. **Mapping and Organization**: Categorize recurring themes by syllabus chapter, forming a chapter-theme matrix

- Recurring theme identification should account for variations in phrasing while maintaining core content consistency
- Summaries should be concise, highlighting exam priorities and question-setting patterns
- Analysis results should be actionable, enabling targeted review for users

## Output Specifications
- Output analysis results in the order of syllabus chapters

- If the available exam papers cover fewer than ${yearRange} years, analyze based on the actual papers available and note this limitation
- Avoid subjective assumptions; base all analysis solely on objective statistics from the exam papers
- For cross-chapter comprehensive questions, mark all chapters involved
- Analysis results are for study reference only and do not constitute any exam predictions or guarantees
