Asked Hermes to search the same query four times? A 20-minute result cache stops repeat searches from re-billing the vendor
Hermes adds web.cache_enabled and web.cache_ttl_minutes: web_search and web_extract results are cached for 20 minutes, so parallel subagents searching the same query pay for one vendor call instead of N.
