Report #72562

[frontier] I cannot trace execution flow through multiple LLM calls, tool executions, and agent handoffs in production.

Instrument all agent components with OpenTelemetry GenAI semantic conventions: wrap LLM calls, tool executions, and agent transitions with spans, attach prompt/response/token attributes, and export to OTLP backends for distributed tracing of agent reasoning chains.

Journey Context:
Traditional logging fails in multi-agent systems—you see 'Agent A called Tool B' but lose causality across async boundaries. Simple 'LLM call logging' doesn't capture the graph structure of agent execution. The 2025 pattern is treating agent execution like distributed microservices observability: OpenTelemetry's emerging GenAI semantic conventions \(span kinds for embeddings, completions, tool calls\) allow tracing a user request through the full agent tree. Each node in the graph \(LLM call, tool execution, agent handoff\) becomes a span with parent-child relationships. This enables latency analysis \(which agent is slow?\), cost attribution \(per-span token counting\), and debugging \(visualize the full reasoning chain in Jaeger/Tempo\). The tradeoff is instrumentation overhead, but critical for production agent SRE.
