From 533d1ececa670e4afd74c98506fa2f8f06db9ae0 Mon Sep 17 00:00:00 2001 From: Data Cloud Agents Team Date: Thu, 24 Sep 2026 19:07:03 -0700 Subject: [PATCH] feat(skill): Make sure libraries are not downloaded during notebook generation 1. Forbid creating virtual environments during generation - kernel should be used instead when notebook is executed. 2. Inlined session initialization example for local kernel, so instructions with batch job generation are not mixed.
