Preview: Attribute blockers to the layer that needs fixing

This engineering preview describes a direction for tracing workflow blockers to the layer that needs investigation. It does not claim automatic root-cause certainty, and it is not a released diagnostic for every voice stack.

This capability is being developed with early-access and design-partner teams; availability depends on the voice stack and evaluation scope. Attribution is limited by the evidence that an agreed integration can expose, so some failures will remain uncertain or span more than one layer.

Move beyond the failed call

Knowing that a call failed is only the beginning of debugging. A missed workflow step might originate in speech recognition, model reasoning, prompt design, a tool call, policy logic, IVR behavior, latency, or telephony. It might also come from an incomplete evaluation requirement. Each possibility leads to a different owner and next action.

The attribution direction is to connect a failed requirement to the evidence observed around it. The system can then identify a supported layer or a short set of plausible layers rather than presenting every problem as an undifferentiated agent failure.

Keep observation and inference separate

Direct evidence should remain distinct from an inferred explanation. A trace may show that a tool received a particular argument. Audio and transcript evidence may show a recognition mismatch. A timing record may show a delayed response. Those observations can support attribution, but the explanation still needs to state what is known, what is inferred, and what evidence is missing.

That distinction is especially important when several components interact. An interruption failure could involve turn detection, prompt behavior, and premature tool submission. Choosing one cause without adequate evidence would create false precision. The useful result may instead be a layered hypothesis and a need for additional instrumentation or review.

Tie blockers to workflow requirements

Attribution begins with a clear failure definition. “The conversation was bad” is too broad to locate. “The agent submitted before confirming the appointment time after an interruption” ties the blocker to an expected workflow step, a condition, and an observable action.

From there, available audio, transcript, trace, tool, policy, and outcome evidence can be aligned around the relevant moment. The preview aims to preserve that chain so a reviewer can inspect why a layer was named. It does not replace the engineering investigation a team may need to confirm and resolve the issue.

Build reusable regressions carefully

Once a failure is understood and fixed, the scoped case can become a regression for a later release when the evidence and permissions allow it. The regression should retain the workflow requirement and relevant condition without implying that one case covers every variation of the problem.

The early-access site includes failure attribution and a reusable regression pack among the planned outputs of a Workflow Readiness Sprint. The depth of attribution possible in a sprint depends on stack access, observability, and evaluation scope.

Teams interested in this preview can join the early-access list with a work email. Joining requires only that email; the form does not collect agent, workflow, stack, or release details. If we follow up, we will ask for the relevant context and constraints before discussing a representative blocker, available evidence, fit, timing, or scope. Joining the list does not guarantee that a root cause can be isolated.
