I noticed that mentioning commands you want gives good results e.g.:

Hi,
I want to replace line with HOSTTOOLS += " svn"
in all layer.conf files under current directory
by using find and sed commands.

If it’s more complicated, pasting parial scrript for LLM to finish gave better results (4 me),
than pure prompt text.

not entirely,
dumb tv turns on in maybe up to 3s
while “smart” tv still needs more than 30s
so now you have crapiest dumb tv on your hands
