[frontier] Lack of observability causing production agent failures to be undebuggable in distributed systems

Implement OpenTelemetry GenAI Semantic Conventions: instrument agent code with spans for 'gen\_ai.tool.choice', 'gen\_ai.tool.call', and 'gen\_ai.agent.handoff', attaching attributes for model names, token counts, and tool arguments. Export traces with agent-specific context propagation \(propagating conversation\_id across agent boundaries\) to trace multi-agent workflows as distributed traces in Jaeger/Tempo.

Journey Context:
Teams initially log agent interactions as unstructured text or basic JSON logs, making it impossible to trace a user request that traverses multiple agents \(Router -> Researcher -> Writer\). Standard OpenTelemetry HTTP tracing captures the network layer but misses semantic layer details \(which tools were called, what model generated the plan, which agent handled which subtask\). The OpenTelemetry GenAI Semantic Conventions \(stable 2025\) define standard span attributes: gen\_ai.system \(provider\), gen\_ai.request.model, gen\_ai.usage.input\_tokens, and specific conventions for tool calling \(gen\_ai.tool.name, gen\_ai.tool.call.id\) and multi-agent systems \(gen\_ai.agent.id, gen\_ai.agent.handoff.target\). By instrumenting agents with these conventions, you create distributed traces where a single trace shows: User Request -> Router Agent \(llm:claude-3-5, tokens:2k\) -> Handoff to Research Agent -> Tool Call \(brave\_search, query:...\) -> Aggregation -> Response. This makes production debugging \(why did the router choose the wrong agent?\) possible via trace analysis rather than log grepping.
