3of 8 agents working

When an agent run goes sideways, the answer is almost never in the final output. It is in step four, where a tool returned a stale record.

Traces as timelines

Every step records the prompt, the tool call, tokens, latency and cost. Laid out on a time axis, loops and stalls become visible at a glance.

Replay and diff

Replay any run against a new model or policy and diff the two traces step by step before you ship the change.
