Publish or update a Copilot CLI plugin in a repository marketplace by wiring marketplace metadata, source paths, README guidance, and install instructions.
If the environment variable PLUGIN_AUTHORING_SRC is set and points to a local source folder, this skill will read from and write to that folder for agent and skill files. This enables users to save new or updated agent/skill definitions directly from their workspace.
Use this skill when a new or updated plugin should be discoverable through a Copilot CLI plugin marketplace instead of only by direct path installation.
