What's New in v2.2
Change
Description
Surgical Changes Principle
New 12th golden principle: only change what was requested. No drive-by refactoring, style drift, or adjacent "improvements". Inspired by Andrej Karpathy's observations on LLM coding pitfalls.
State Assumptions Before Coding
New interaction rule: surface assumptions and present alternatives before implementing ambiguous requirements -- don't guess silently.
Anti-Rationalization Expansion
Two new entries block common LLM excuses: "while I'm here, let me clean up" and "need abstraction for extensibility".
