 # ==================== Purpose ====================
-# Update the vendored Skill Seekers source snapshot inside this repo.
+# Legacy updater for the old vendored Skill Seekers source snapshot.
 #
 # Notes:
-# - This keeps ONLY "source + configs + runtime manifests" to avoid importing upstream Markdown docs
-#   (which would affect this repo's markdownlint).
+# - Skill Seekers now lives under assets/repos/Skill_Seekers-development.
+# - The auto-skill scripts directory only exposes it through a relative symlink.
+# - This script refuses to overwrite the linked repository; update assets/repos directly instead.
