Now and then it checks that the reused data matches what it should be, and catches wrong data before sending. How often that check runs is now scaled by a number set remotely by Anthropic, between 0.1 and 1. Any value outside that range counts as 1. Whether the first check happens in a session is now decided once per session, rather than by fixed limits.\n\n**Why**\n\nAnthropic can now raise or lower how often these checks run without shipping a new version. Nothing you do changes.\n\n- Area: API Requests\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
