This looks like such a nice cli/tui talking/chat harness - an agent with which I can work on non-coding tasks (where it literally doesn't need any tool - maybe a read tool for few files in that folder, or not even that) - writing critique (w/ strict strict for on generation/suggestion), analysis, summary etc.

I've been so far using pi like this:

> pi --offline --no-extensions --no-skills --no-prompt-templates -nc -nt --thinking low --system-prompt "$(cat <custom purpose path for system/role prompt>)

Purpose was to reduce token usage to an absolute minimum (zero extra token) as often I use this per use API keys (and not my GLM key, which let's say, is a bit "different" when it comes to conversations).

Are there any other tools specifically designed for such tasks? Even though hax looks like the absolute bare minimum one can go while still being usable.

I wish there was also tools that would refuse and reject (or prevent) models from inserting "thinking" messages into responses. They keep appending those and that very soon that part starts snowballing on steroids.
