Measure a skill/behaviour's real trigger rate across prompts × trials. Defaults
to the real claude CLI (claudeEvalDriver); pass { evalDriver } to drive a
second harness — e.g. measureTriggerRate(spec, { evalDriver: codexEvalDriver })
from vigiles/codex (the eval-tier analog of runHarnessTest's { adapter }).
Requires that harness's binary + auth.
Measure whether a skill's description actually FIRES (recall + precision) by running real prompts against a real model. Spends money.
⚠️
paid_overstates slightly: an injectedevalDriverreplaces the billed path, andstubSkillBodiesmakes the default path much cheaper without making it free. The DEFAULT path bills.
