Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, valid manifest defaults, and personal-marketplace entries by default. Use when Codex needs to create a new personal plugin, add optional plugin structure, generate or update marketplace entries for plugin ordering and availability metadata, or update an existing local plugin during development with the CLI-driven cachebuster and reinstall flow.

From README

Plugin Creator Run the scaffold script: Edit /.codex-plugin/plugin.json when the request gives specific metadata. The scaffold starts with valid defaults and must not contain [TODO: ...] placeholders. Generate or update the personal marketplace entry when the plugin should appear in Codex UI ordering: Only specify --marketplace-name when the default personal marketplace name is already taken or installed and you need to seed a different new marketplace file: Only use a repo/team marketplace when the user specifically asks for that destination: When the user specifies a marketplace path, make sure that marketplace is actually installed before telling the user to reinstall from it. The default personal marketplace file at /.agents/plugins/marketplace.json is discovered implicitly, but other marketplace paths are not. On Windows, use the equivalent path under the user profile.
