Behind a remotely controlled switch, some of these mentioned files are no longer added to the list of files Claude is told you referred to.\n\nThe switch is off unless it is turned on remotely. The flag server returned it off for this site's account and for the anonymous baseline. No reading has been taken under this release yet.\n\n**Why**\n\nThis may be a quiet trial of a change to how some @-mentioned files are passed to Claude. With the switch off, nothing changes.\n\n- Flag `tengu_twinkly_babbage`: Off in both readings (read for one account on one subscription tier against v2.1.321; 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: File Mentions\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
