Report #87466

[research] OpenTelemetry traces for agents are unreadable because they lack LLM-specific context, making it impossible to debug why an agent chose a specific action

Enrich LLM and tool spans with semantic attributes: gen\_ai.request.model, gen\_ai.prompt, gen\_ai.completion, gen\_ai.usage.input\_tokens, and tool.name / tool.args. Do not rely on default HTTP spans.

Journey Context:
Standard HTTP instrumentation just shows a request to an LLM API endpoint. It doesn't show what system prompt was used, what tools were available, or what the model 'thought'. Without adding GenAI semantic conventions to the spans, debugging an agent failure requires reproducing the exact state and re-running, which is often impossible. Explicit span attributes bridge the gap between observability and evals.
