From a3291302278bce038e007dfeac239baa9ff26b44 Mon Sep 17 00:00:00 2001 From: mimran-khan Date: Thu, 27 Aug 2026 01:33:56 +0530 Subject: [PATCH 1/4] fix(tier3): keep --no-llm negative cases off-skill The default template asked what the skill does by name, which is an explicit invocation, not a negative case.
