Thoughts on Claude Code's Workflow feature

I like the idea of Claude’s workflow thingy but since it’s writing code, it keeps failing with these kind of errors:

In addition, the UI of Claude feels a bit overwhelming to me.

There’s also some strong validations around making the workflow deterministic and I wonder if it could still be handled? I’m also curious on why they’re not giving guidance to the model about this and/or linting workflow code to have this be caught before the harness runs the workflow.
