Report #64306

[frontier] Agent traces are opaque black boxes: spans show 'LLM call' but hide semantic details \(prompt template version, retrieved chunks, tool input schema\), making production debugging impossible

Instrument agents with OpenTelemetry GenAI semantic conventions \(experimental\): use \`gen\_ai.system\` attribute to tag vendor, \`gen\_ai.usage.input\_tokens\`, \`gen\_ai.prompt.\*\` events for prompt content, and custom events for RAG retrieval \(\`db.chunks.retrieved\`\). Correlate spans across agent handoffs using \`tracecontext\` propagation. Visualize in Jaeger/Tempo with GenAI-specific queries \(latency by prompt template version\).

Journey Context:
Generic OTel traces lack GenAI semantics. Standardized attributes allow cross-tool observability \(LangSmith, Honeycomb, Datadog\). Critical for production agent ops. Tradeoff: instrumentation overhead vs. debuggability.
