Create a canvas extension

Use this skill only for the github/awesome-copilot repository. Canvas extensions are reusable source components. They do not have a plugin.json under extensions/.

Required decisions

Before creating files, ask for each missing value:

1. Extension ID: lowercase kebab-case, matching the source folder and plugin name.
2. Display metadata:
   • description
   • version (default 1.0.0)
   • author name and optional URL
   • keywords (lowercase, hyphenated, maximum 10)
   • repository and license (default to the repository URL and MIT when appropriate)
3. Canvas entrypoint: confirm whether the extension already has extension.mjs. If not, create a minimal entrypoint only when the user provides enough implementation details; otherwise create the directory and leave an explicit TODO.
