Agent C audits form validation. An hour later, they report conflicting results. Agent A saw a working cart. Agent B saw missing prices. Agent C's form validation report contradicts Agent A's observations. What went wrong? They weren't looking at the same page. They weren't in sync. This is the coordination problem in parallel multi-agent systems. When agents execute browser tasks simultaneously, they diverge on visual reality. One agent sees the page in state X. Another sees state Y. They make contradictory decisions. Your workflow fails. The Root Cause: Text-Only Coordination Today's multi-agent systems coordinate using API responses and HTML parsing. Agent A parses: "Cart total: $99". Agent B parses: "Price tag not found". Agent C parses: "Form field is visible". But they never actually saw the
