CAPRA is a multi-agent LLM system that generates personalized, template-compliant LaTeX feedback on software architecture deliverables. It uses specialized agents, PyMuPDF, and gpt-4o to extract and analyze text and UML diagrams, with evidence anchoring and consistency management to ensure reliability. A preliminary evaluation of 10 student reports shows CAPRA met 88.8% of eight criteria and achieved moderate inter-rater agreement (kappa = 0.582), with each report processed in under 4 minutes.
