Interesting.

In your Github, the JSON format shown for defining custom workflows is very simple. I wonder if that limits the detail in the state-related instructions and error messages you can send to a model.

For example, in state transitions, does your tool just tell the model something like "you are in 'act' mode and no longer in 'plan' mode, here are your new available tools"? Seems difficult to give it any more informative messages given how simple the workflow definitions are. Likewise when the model attempts to do something that's not supported for tools in the given phase.
