+"""Build the skills-only package the OpenAI plugin portal uploads.

+The portal's Skills step takes a ZIP whose root holds a portable Agent Plugins
+manifest and a skills/ directory. Everything inside comes from the canonical
+source, so this package can never describe workflows we do not ship. The build
+is byte-reproducible: entries are sorted and timestamps fixed, which lets
+scripts/validate.py fail when the committed ZIP drifts from the skills.
