We present <strong>CompanionCast</strong>, a general framework for orchestrating multiple specialized AI agents as social collaborators within a live shared context, integrating multimodal event detection, rolling context caching, and spatial audio to enhance co-presence. Validated through sports viewing, pilot studies with soccer fans show that CompanionCast significantly improves perceived social presence and emotional sharing compared to solitary viewing. This work was conducted in part during a Ph.D. research internship at Dolby Laboratories and accepted at the ACM CHI 2026 Workshop on Human-Agent Collaboration.</p>
