Is it possible to use the SDK to manage plugins?

[GordonSmith]

Specifically I am thinking of adding a VSCode extension that wraps the "marketplace" add/remove install type capability and rather than calling cli via stdin/out I thought it would be nicer to use the SDK?

From the --help:

Marketplace Management:
  copilot plugin marketplace add <source>    - Add a marketplace (e.g., owner/repo)
  copilot plugin marketplace remove <name>   - Remove a marketplace
  copilot plugin marketplace list            - List registered marketplaces
  copilot plugin marketplace browse <name>   - Browse plugins in a marketplace

Plugin Management:
  copilot plugin install <plugin>@<market>   - Install a plugin from marketplace
  copilot plugin install owner/repo          - Install directly from GitHub repo
  copilot plugin install owner/repo:path     - Install from repo subdirectory
  copilot plugin install <url>               - Install directly from git URL
  copilot plugin uninstall <plugin>@<market> - Uninstall a marketplace plugin
  copilot plugin uninstall <plugin>          - Uninstall a directly installed plugin
  copilot plugin update <plugin>@<market>    - Update a marketplace plugin
  copilot plugin update <plugin>             - Update a directly installed plugin
  copilot plugin list                        - List installed plugins

Examples:
  copilot plugin marketplace add anthropics/skills
  copilot plugin install document-skills@anthropic-agent-skills
  copilot plugin install owner/my-plugin
  copilot plugin install owner/repo:plugins/my-plugin
  copilot plugin update document-skills@anthropic-agent-skills
  copilot plugin update my-plugin
  copilot plugin uninstall my-plugin
