Two of its sections can be switched on or off remotely by Anthropic:\n\n- a section about reduced delegation, which is on unless it is switched off remotely\n\n- a section about tool parameters, which is off unless it is switched on remotely\n\nBoth switches existed before. The code that reads them was reorganised, but apart from internal renaming there is no clear difference in how these sections are included.\n\n**Why**\n\nIn practice, nothing about these two sections appears to have changed, and there is nothing you need to do.\n\n- Flag `tengu_slate_bittern`: Not enough to say (read for one account on one subscription tier against v2.1.310; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Flag `tengu_silent_harbor`: Off in both readings (read for one account on one subscription tier against v2.1.310; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: System Prompt\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
