When a remotely controlled switch is on, it now also starts a second download of each attachment, a copy intended for the model. Before, it made only one download.\n\nThe limit on how much downloaded data Claude Code holds at once now counts what is actually held in memory.\n\nThe switch read on for this site's account and for an anonymous account in the most recent reading, taken before this release. It had been off in the reading before that.\n\n**Why**\n\nThis changes how images and files reach Claude in remote sessions, and holding two copies uses more memory, which the updated limit is set up to track.\n\n- Flag `tengu_functional_flute`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.323; 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: File Attachments\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
