That list can now include one more capability, added when an extra check passes. Before, the list came from two sources plus one condition.\n\nThe same step also reads a remote switch about automatic enabling for editors. It is off when the server sends nothing. The flag server has answered on for this site's account and for an anonymous baseline since a reading on 2026-10-07.\n\n**Why**\n\nPrograms that drive Claude Code, such as code editors, may learn of one more thing Claude Code supports at the start of a session.\n\n- Flag `tengu_ide_rc_auto_enable`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.312; this account: on, anonymous baseline: on, 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: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
