← idempotent / no-retry — say whether re-running an action is safe
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-17.5 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -18.5 to -17.5
The result is on the helpful side of this metric's neutral point.
