- generate_question: Creates custom quiz challenges filtered by specific topics, difficulty levels, or question formats.
- evaluate_answer: Analyzes your responses to open-ended design problems, providing a 1-10 score, technical critique, and actionable suggestions for improvement.
Use Cases
- Targeted Review: Use get_topics to identify your weaker areas, then call generate_question with a specific topic filter like "caching" or "databases" to drill down on those concepts.
- Interview Simulation: Practice responding to open-ended architecture prompts, then use evaluate_answer to receive a detailed breakdown of your trade-off analysis and structural quality.
- Progress Tracking: Regularly generate questions to measure your improvement across different difficulty levels, using the rubric coverage feedback to identify gaps in your design methodology.
