Your agent traces are your best eval data.
The most important failures only show up in production, and they rarely make it into your test set.
DigitalOcean's Signals flags sessions where users got frustrated or tools failed and turns them into evals with one click. Simulations then replay them against your fix on your agent's real harness before it ships.
If you're running agents in production, you need this loop.
