I wrote my own harness designed to feel like a unix util. If you're worried about security, mine is a single file shell script less than 1,000 loc. It only depends on llama-cli and a few posix shell tools. So it has no way to dial anywhere and no security problems hiding in some dependency.

But it's not optimized for coding specifically. It can edit files fine using Aider style edits. I've used it to write to do lists as a test. But I more designed it with the idea to be my personal debugging tool if I ran into any weird things while using Linux on a laptop.
