Report #79441

[research] Observability stack only captures LLM inputs/outputs and tool calls, missing the agent's internal reasoning, making debugging impossible when the agent takes a weird action

Force the agent to emit its reasoning as a structured span\_event \(e.g., agent.thought\) before every tool call. Include the intent and expected\_outcome in the span attributes.

Journey Context:
Black-box agents are undebuggable. If an agent calls delete\_file, you need to know why. Standard OpenTelemetry LLM spans just show the prompt/completion. By requiring the agent to output its reasoning as a structured telemetry event, you create a searchable, filterable log of intent, which is crucial for post-mortem evals and identifying where the agent's logic diverged from reality.
