From 5f95fac62631482a4887aaa720f33f393ebdbb62 Mon Sep 17 00:00:00 2001 From: Teknium <127238744+teknium1@users.noreply.github.com> Date: Tue, 20 Oct 2026 01:27:07 -0700 Subject: [PATCH] fix(tool_search): drop the managed-worker delegation diagnostic now that workers delegate there and to use kanban_create instead. With owner-reserved children that is false, so the 'delegation' entry and its helper go: a turn whose toolsets leave delegation off now gets the generic 'not available in this execution context' answer, in a worker or not, and a turn that has delegate_task keeps the ordinary 'call it directly' guidance.
