Report #39811

[research] Agent costs spike unexpectedly, but it is unclear which specific tool or step is consuming the most tokens

Tag every LLM call in your telemetry with the specific tool context that triggered it, and aggregate token usage by tool name in your observability dashboard.

Journey Context:
Total token usage per run is a useless metric for optimization. A code-generation tool might use 10x the tokens of a routing tool. By propagating a tool\_name attribute in the OTel span for the LLM call, you can isolate cost centers. You might find that a poorly written prompt in a minor tool is consuming 60% of your token budget due to massive system prompts.
