Could you build this?
Partial Trace viewing and replay UI are vibe-codeable, but reliably finding the step that caused a wrong answer and making replays deterministic requires novel causal-attribution methods.
What it would actually take: The stack would be an agent-tracing SDK (OpenTelemetry-style spans), a replay engine that records and re-executes model and tool calls, and a web UI. The hard part is root-cause attribution, which needs counterfactual evaluation and LLM-judge calibration. That calls for evaluation-research experience and real agent workloads to validate.
