Runtime description

The following is the tool's own agent-facing description, reproduced from the reviewed registry. It can contain implementation terminology; it does not expand the public stability commitment.

Read the agent-facing description

Record and report LLM token/latency metrics — use to track efficiency and optimize context usage.
WORKFLOW: action=record during each LLM call, then action=report for readable summary.
Actions: record (log event), report (readable summary), json (machine-readable),
reset (clear data), status (storage info).
ANTIPATTERN: not for debugging code behavior — this tracks token/latency stats only.
record requires llm_input_tokens + llm_output_tokens.
