So how does it save me from having to read the man page?
How do I know if the command is safe to execute when I can't trust LLM output?
Also, for "safe" commands, how do I know that it is doing what I asked it to do (without reading man pages) when I can't trust LLM output?
Anything your script returns is "untrusted input" to me which requires careful scrutinization. Which means this adds more work, not lessens it. While also making running commands cost real money!
