Appreciate the kind words.

Re copy for agent, I originally had a build step that was build into diffui itself, but what I found was that:

1. People wanted their own agent with its own skills/extensions to do the work

2. People wanted to build in their own codebase / style

The copy for agent was a way to allow for that. I do have a MCP as well, but I find I actually really enjoy the process of doing visual exploration on the canvas first, then handing it off to an agent after.

Agree with both points, at least for folks who already have that infra (which I do). Made it much simpler than trying to "extract" things out of a tool that wanted to do everything.
