So the auto create plugin script you used needs to be updated. Originally I thought most of the plugins were going to be protocols.

You can delete the definition.py file and then move the plugin code up a level from the v1_0 folder.

Then in places where the agent uses the --plugin config the plugin name would be cheqd instead of cheqd.v1_0.

Sorry about that. Hope it's not too much work to update, and I'll try and update the script to avoid this for the next person.

Did a quick over and it's looking really good 👍 Will try and find some time to go over it closer.
