What's Wrong?

2.0.30 "Deprecated output styles. Review options in /output-style and use CLAUDE.md or plugins instead" .

Please consult user's idea first when doing such big move. Personally I don't want this exchange because per the doc at "https://docs.claude.com/en/docs/claude-code/output-styles", instead of output-style, you will need to rely on sessionstart hook to control the style. This won't work as effective as the current output-style. For me, Claude by default is super chatty or verbose, and I like it to be extremely succinct, thus I have a custom output-style to control it which works very well. It won't say "you are absolutely right", and it will not even say a thing during its action until it needs clarification from me.

I want this feature to be retained. Who the hell decided this can be achieved via plugin? this is not the same. output-style override part of the system prompt for it to be effective. this is not the same as hook's prompt injection which will for sure loses its power after several rounds.

What Should Happen?

Keep output-style

Is this a regression?

Yes, this worked in a previous version
