Report #50672

[research] Agent runs are black boxes; impossible to debug silent failures or infinite loops in production

Instrument agent runs with OpenTelemetry \(OTel\) spans for every LLM call, tool execution, and handoff. Attach token usage, latency, and prompt versions as span attributes to enable filtering and root-cause analysis.

Journey Context:
Just logging the input and output of an agent is useless when it fails. You need to know \*why\* it called a tool or \*what\* it hallucinated. OTel provides a standard for distributed tracing that maps perfectly to agent architectures: a trace for the run, spans for steps, and attributes for metadata. People often build custom logging, which fails at scale and lacks the tooling \(like Jaeger/Datadog\) to visualize nested agent handoffs.
