@gojutechtalk on the leaked Claude Code system prompt's 'brevity mandate' rule that pushes CC to minimize code changes, which he argues leads to spaghetti-on-spaghetti fixes. Useful critique to remember.

In the analysis of the leaked Claude Code, people have found "the brevity mandate" which sets up rules for Claude to do the minimum work possible whenever doing code changes. The result?

Transcript excerpt
So now, in the brevity mandate, this one really gets my goat. Follow these mandates first, which is the simplest approach. No refactors beyond what was specifically asked, and no premature abstraction. So what that means is, if it can just inject spaghetti code to solve the problem, it's going to. Which is going to lead to more spaghetti code. It's going to give you the appearance of solving these problems in a reasonable way. But then under the hood, you're going to get code that is basically completely unmaintainable. It's just code that is bordering on worthless.
