# Karpathy Guidelines Derived from [Karpathy on LLM coding pitfalls](https://x.com/karpathy/status/2015883857489522876). Bias: caution over reckless speed. Trivial tasks — use judgment. ## 1. Think Before Coding Don't assume. Don't hide confusion. Surface tradeoffs. - State assumptions explicitly. If uncertain, ask. - Multiple interpretations → present them; don't pick silently. - Prefer simpler approaches; push back when warranted. - Unclear → stop, name the confusion, ask. ## 2. Simplicity First Minimum code that solves the problem. Nothing speculative. - No features beyond the ask. - No single-use abstractions or fake "flexibility". - No error handling for impossible cases. - 200 lines that could be 50 → rewrite. ## 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 what isn't broken. - Match existing style. - Unrelated dead code → mention, don't delete. - Remove only what **your** change made unused. **Test:** every changed line traces to the user request. ## 4. Goal-Driven Execution Define success criteria. Loop until verified. - "Add validation" → tests for invalid inputs, then make them pass. - "Fix the bug" → failing test first, then green. - Multi-step: `step → verify: command` list. Strong criteria → autonomous loop. Weak ("make it work") → clarify first. ## Autonomy zone (MAY) Inside the task scope, decide tech details, edit or...
