Ask HN: Everybody and their dog is building an agentic CLI. Any command bins?

I just want to do something along the lines of

`agent.bin --init task.log` # logs all of my inputs and the agent's outputs

`agent.bin --set-rag rag.md` # optional if already set in config

`agent.bin --set-system-prompt system.md` # optional if already set in config

`agent.bin 'Build a single-page hero website for me'` # could also be --prompt

Then finally finishes with an ASCII art of a 'Task Finished' card with summary.

What's a good one? Is there a good one?
