From c2fed34354e112007a021ecae0207e43ebfb4ad3 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 1 Oct 2026 23:36:28 +0000 Subject: [PATCH 1/2] Remove npm from the agent runtime image and stop hiding npm/Go from Trivy npm was installed in its own layer and never removed, so it shipped in the image, and the Trivy skip-dirs entry for usr/lib/node_modules/npm hid exactly what customers' scanners report. Nothing runs npm or npx at runtime (the agent execs the installed snyk-broker bin), so fold the Node install, npm upgrade and snyk-broker install into one RUN and delete npm/npx at its end. It must be the same layer, because the nodejs package itself installs npm. Also drop usr/local/go from skip-dirs: the Go toolchain ships for scaffold apps, so its stdlib CVEs are real findings customers see.
