It applies when your latest message came from the Claude iOS app, Android app, desktop app or website. Its text is \"The user's latest message came from the Claude\" followed by the app's name. It is added ahead of the workflow keyword notes and sits behind a feature check.\n\nA related flag, `tengu_rosy_llama`, returned off from the flag server for this site's account and for the anonymous baseline. Those readings were not taken under this release.\n\n**Why**\n\nThis gives the model a new piece of context, so it can know which Claude client you are typing on.\n\n- Flag `tengu_rosy_llama`: Off in both readings (read for one account on one subscription tier against v2.1.319; 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: Claude Apps\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 4\/5\n- Scope: individual\n- Heads-up: no\n- Present in the build but not switched on"}
