#
# Package the Superpowers Codex plugin as a rootless archive for portal upload.
#
# The Codex portal artifact differs from the old openai/plugins sync flow:
# it is a standalone archive, but it still needs the OpenAI-owned
# skills/*/agents/openai.yaml metadata that used to be preserved from the
# destination plugin repo. Seed that metadata from a prior official package.

Usage:
  scripts/package-codex-plugin.sh [options]

Options:
  --output PATH            Write archive to PATH.
                           Default: ../_tmp/sup-codex-packaging/superpowers-VERSION.zip
  --format FORMAT          Archive format: zip or tar.gz. Default: zip.
                           If --output ends in .zip, .tar.gz, or .tgz, that
                           extension is used when --format is omitted.
  --metadata-source PATH   Prior official package directory, .zip, or .tar.gz used to
                           seed skills/*/agents/openai.yaml.
                           Default: ../_tmp/sup-codex-packaging/superpowers,
                           falling back to superpowers.zip, then superpowers.tar.gz
  --ref REF                Git ref to package. Default: HEAD.
  --allow-dirty            Permit a dirty working tree. The archive still uses --ref.
  --keep-stage             Print and keep the temporary staging directory.
  -h, --help               Show this help.

The archive is rootless: .codex-plugin/, assets/, skills/, README.md, LICENSE,
and CODE_OF_CONDUCT.md sit at the archive root. Source-only repo files, hooks, tests,
docs, and other harness manifests are intentionally not shipped.
