From 0d77a4023c7b5e21cb1980ef0d38e7863d83d80b Mon Sep 17 00:00:00 2001 From: mudler-agent Date: Tue, 20 Oct 2026 13:14:49 +0200 Subject: [PATCH] fix(sound): enumerate expansion keys (#12787) List the existing keyscale vocabulary in the expansion tool schema. Keep optional keys omitted when unspecified and retain server validation. Quote rejected keys in validation errors, with a bounded prefix, so a failed request exposes the invalid notation without other arguments.
