Claude Code can now show a warning when the combined size of these files goes over a limit. The warning gives the total number of characters and the limit.\n\nThe warning appears only when a server-controlled switch, off unless it is switched on remotely, allows it and a further check on your environment passes.\n\n**Why**\n\nIt tells you when your instruction files have grown too large, so you can trim them.\n\n- Flag `tengu_jolly_aurora`: Not enough to say (read for one account on one subscription tier against v2.1.288; this account: no value returned, anonymous baseline: no value returned, 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: Memory\n- Names: `CLAUDE.md`\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
