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". |
