Behavioral guidelines to reduce common LLM coding mistakes through explicit assumptions, simplicity, and verifiable success criteria.

- Emphasizes surfacing assumptions and tradeoffs upfront rather than making silent decisions or hiding confusion

- Advocates for minimum viable code with no speculative features, abstractions, or error handling beyond what was requested

- Requires surgical, focused edits that touch only what's necessary and match existing code style without improving adjacent code

- Transforms tasks into verifiable goals with explicit success criteria and multi-step plans that enable independent verification loops

Karpathy Guidelines

Behavioral guidelines to reduce common LLM coding mistakes, derived from Andrej Karpathy's observations on LLM coding pitfalls.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

- 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.
