When the forked agent finishes, its returned messages used to include everything it began with. By default it now leaves out the messages it inherited and returns only its own.\n\nA new `keepPreservedMessages` option brings back the inherited messages. A second option deals with cutting tool results.\n\n**Why**\n\nWhatever receives a forked agent's results now gets just what the fork added, unless it asks for the inherited messages too.\n\n- Flag `tengu_wild_tome`: 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: Subagents\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
