Is there documentation/guide/skills for developing Orca plugins?

### Details

Hi team,

I'm interested in developing plugins for Orca. Could you please let me know if there is any documentation, guide, or skills support for plugin development?

Specifically, I'd like to understand:
- The development approach/methodology for Orca plugins
- The plugin API and interfaces
- Any coding standards or specifications
- Whether there are official skills or templates available

Any pointers to docs, examples, or community resources would be greatly appreciated. Thanks!
