Report #99295

[architecture] Impossible to debug why a multi-agent system produced a wrong or inconsistent answer.

Emit OpenTelemetry traces where each agent turn, tool call, and handoff is a span carrying input state, output, and latency; correlate all spans with a single trace ID across agents.

Journey Context:
Multi-agent bugs are emergent from interaction, not a single bad prompt. Without distributed tracing you cannot reconstruct which agent decided what, when, and on which state. Standard LLM trace semantics let you follow a request across agent boundaries and replay the exact sequence of decisions.

environment: Production multi-agent systems where output quality, cost, or latency regressions need root-cause analysis. · tags: observability tracing opentelemetry debugging llm-spans · source: swarm · provenance: https://opentelemetry.io/docs/specs/semconv/gen-ai/llm-spans/
