When the skill finishes, it's marked as stopped, completed, or failed in that registry and then removed. Previously, a forked skill ran silently, sharing the caller's cancel control and without appearing in the task registry at all.\n\n**Why**\n\nThis makes background skill runs visible and individually cancellable like other tracked background tasks, rather than being invisible to whatever monitors or manages running tasks.\n\n- Flag `tengu_harbor`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.271; 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- Flag `tengu_lively_waffle`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.271; this account: on, anonymous baseline: on, compiled default: on) 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: Skills\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 3\/5"}
