       | Anyway, even if you give your agent permission, there's no secure
       | way to know whether what they're asking to is what they'll
       | actually do, etc.

       | system where I can then have each one pulled out and `claude
       | -p`'d but I'd rather just integrate an open coding agent into the
       | loop because it's less janky and then I'll have it try to fix the
       | problem and propose a PR for me to review. If anyone else has
       | used pi.dev or opencode or aider in this mode (completely non-
       | interactive until the PR) I'd be curious to hear.

       | It's a great harness for use with smaller parameter size models
       | given the system prompt is quite a bit shorter vs Claude or Codex
       | (and it uses a nice small set of tools by default).

       | My current fave harness. I've been using it to great effect,
       | since it is self-extensible, and added support for it to
       | https://github.com/rcarmo/vibes because it is so much faster than
       | ACP.

       | Is that an official term "coding harness"

       | Wondering if you wanted a similar interface (though a GUI not
       | just CLI) where it's not for coding what would you call that?
       | 
       | Same idea cycle through models, ask question, drag-drop images,
       | etc...
