1 in 6 adults worldwide care for an aging or chronically ill relative — managing their loved one's healthcare across a stack of paper, three portals, and four specialists who never talk to each other. Drug interactions go unflagged. Kidney trends are spotted six months late. Appeals expire silently.

CareCoord is a five-agent medical document coordinator built entirely on Claude Opus 4.7's Managed Agents API. Photograph anything — pill bottles, lab printouts, insurance denial letters, appointment cards, in any language — and five specialist agents (Medication, Insurance, Medical, Appointments, Orchestrator) analyze in parallel. The orchestrator finds the cross-domain connections no single specialist sees: the kidney decline + the diuretic-NSAID pair + the denied claim still inside its appeal window are ONE event, not three.

From that single analysis the engine renders five distinct documents from structured tool calls — caregiver brief (grade 6), SBAR clinical handoff, insurance appeal, attorney evidence pack, bedside note (grade 4) — re-rendered instantly when you toggle audience.

Every load-bearing Opus 4.7 Managed Agents primitive ships in production: agents, environments, sessions, custom tools, memory filesystem, outcomes, xhigh thinking, permission policies, prompt caching, SSE streaming. 417 tests across 35 files, zero live API calls. Demo Mode runs in 60 seconds with $0 LLM spend.
