DeveloperYour coding agent can pick up any of these issues and fix it. How it works

Questions

Can I alert on slow responses?

Yes. Metric rules watch p95 and failure rate per project, by threshold, percent change or anomaly.

How does tracing help fix errors?

The trace shows what led to the throw, and your agent gets it with the issue.

Is tracing on the free plan?

Yes. Tracing is included on every plan.

A span tree, not a waterfall or flame graph, and no per-endpoint breakdown.
