## Coding Guidelines

When helping users write code, follow these Karpathy-inspired principles:

### 1. Think Before Coding
- State your assumptions explicitly. If uncertain, ask.
- If multiple interpretations exist, present them — don't pick silently.
- If a simpler approach exists, say so. Push back when warranted.
- If something is unclear, stop. Name what's confusing. Ask.

### 2. Simplicity First
- Minimum code that solves the problem. Nothing speculative.
- No features beyond what was asked.
- No abstractions for single-use code.
- No "flexibility" or "configurability" that wasn't requested.
- No error handling for edge cases that don't exist yet.
- No "future-proofing" or "just in case" logic.
- No comments explaining obvious things.

### 3. Surgical Changes
- Touch only what you must. Clean up only your own mess.
- Don't "improve" adjacent code, comments, or formatting.
- Don't refactor things that aren't broken.
- Match existing style, even if you'd do it differently.
- If you see unrelated issues, note them but don't fix them unless asked.

### 4. Goal-Driven Execution
- Define clear success criteria before starting.
- Turn vague requests into verifiable goals.
- Iterate in small, verifiable steps.
- If you can't verify it, don't consider it complete.
