The monorepo release pipeline updates this GitHub repository but does not update the public directory. codex plugin add and marketplace upgrades manage local installations, not the public listing. Do not use the old packages/codex-plugin build directory, openai/plugins, or the portable cursor-plugin package for this upload.
