Suitable tasks

Connect an incorrect answer to the retrieval, model call or tool steps that produced it.

Limits and checks

A trace can contain sensitive inputs, documents and outputs. Define what is recorded before instrumentation.

A repeatable trial

Using fictional data, trigger a missing reference and a tool error. Check their distinction in the trace and masking of a test confidential marker.

How to decide

Keep instrumentation when it explains failures without retaining more data than needed.

Frequently asked questions

Does a successful trace prove a correct answer?

No. Technical success and output quality need separate criteria.
