I've not heard of that before but after looking into it I think they are solving different problems.

Dotprompt is a promt template that lives inside app code to standardize how we write prompts.

Axe is an execution runtime you run from the shell. There's no code to write (unless you want the LLM to run a script). You define the agent in TOML and run with `axe run <agent name> and pipe data into it.
