+# Source repo request workflow for NVSkills CI (signing pipeline).
+# Triggered by a maintainer/admin commenting `/nvskills-ci` on a PR
+# that changes skills/, OR by the signature-push back from
+# nv-nvskill-ci[bot].
+#
+# Inlined version (provided by NVCARPS team) — no `uses:` reusable
+# workflow call to avoid the public→internal access restriction.
+# Instead, dispatches NVIDIA/nvskills-ci:nvskills-ci.yml via the GitHub
+# REST API with the NVSKILLS_CI_DISPATCH_TOKEN secret.
+#
+# Onboarding tracked in NVBug 6209970.
