The user is not watching in real time\". It is meant for sessions running without you watching. The check that decides whether this guidance applies used to return the full guidance text, or nothing. It now returns only yes or no. The guidance text is no longer written in that check.\n\nThe check still depends on a server-controlled setting that falls back to on when the server sends nothing. Readings taken before this release found it on, both for this site's account and for an anonymous one.\n\n**Why**\n\nThe autonomous-operation guidance may now reach Claude in a different way. That could change how Claude behaves in sessions you leave running on their own.\n\n- Flag `tengu_amber_sextant`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.312; this account: on, anonymous baseline: on, 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- Area: System Prompt\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
