I swear to god... What Claude Code version introduced this "system reminder"?

They had obnoxious "output efficiency" instructions in previous versions. The community was patching it out via shell script.

It actually improved Opus's performance too.

A few days later, they deleted the instructions targeted by this script, breaking it.

Now they're doing this?
