This is stage **4 of 5** of [the AGNT5 loop](/docs/get-started/loop.md). Every run produces a durable trace — open Studio and walk it step by step.

**What's in a trace:**

- Each step's input, output, and duration
- Model calls — prompt, response, token count, cost
- Retries — how many attempts, the error each time, the final outcome
- State at each checkpoint — what survives a worker restart
- Failure points — exactly which step raised, where replay would resume

**Where to look:**

- [Studio → Runs](https://app.agnt5.com/runs) — every invocation, searchable by workflow, status, input
- Click a run → drill into the trace tree → click any step for its full record

When you find a regression, jump to [Improve](/docs/get-started/improve.md) to capture it into an eval.
