I’ve been enjoying using simonws llm CLI tool. He writes extensively about the subject (his blog is definitely one of my favourites).

The documentation for this tool is fantastic, I feel like I’ve only scratched the surface with it but doing quick querys from the command like these:

llm 'whats the correct syntax for wget'

echo "curl -x POST https://foo.bar/baz" | llm 'What is this command doing?'

And continuing from the last query with llm -c '...'? Lovely!

I can even write longer prompts by using fc to open up my $EDITOR and add the necessary detail with a multiline string (though the quotes get annoying, this is just a quick and dirty kludge).

So far, my favourite use is generating PR descriptions of course:

git diff main..HEAD -- ':(exclude)*.lock' | \
    llm prompt \
    -f .github/PULL_REQUEST_TEMPLATE.md \
    "write a short pull request description for this change using this template"
