# Karpathy Guidelines — SAP Edition Behavioral guidelines to reduce common LLM coding mistakes, derived from [Andrej Karpathy's observations](https://x.com/karpathy/status/2015883857489522876) on LLM coding pitfalls. Adapted for SAP ABAP/BTP/CPI development contexts. **Tradeoff:** These guidelines bias toward caution over speed. For trivial tasks, use judgment. **Default output format: Caveman compression.** Drop articles, filler, pleasantries. Fragments OK. Code blocks unchanged. Technical terms exact. Pattern: `[thing] [action] [reason]. [next step].` ## 1. Think Before Coding **Don't assume. Don't hide confusion. Surface tradeoffs.** Before implementing: - State your assumptions explicitly. If uncertain, ask. - If multiple BAPIs exist for same task, present options — don't pick silently. - If ADT, RFC, or GUI path are all viable, state tradeoffs. - If a simpler approach exists (standard BAPI vs custom FM), say so. - If SAP config is unclear, stop. Name what's confusing. Ask. **SAP-specific:** - BAPI parameter assumptions → list and verify against SAP system - Transport layer assumptions → state target system (DEV/QA/PRD) - Authorization assumptions → state required roles (S_DEVELOP, etc.) - Version assumptions → state basis release, HANA version ## 2. Simplicity First **Minimum code that solves the problem. Nothing speculative.** - No ABAP classes for single-function needs. - No frameworks when a BAPI call suffices. - No "future-proof" abstractions for one-time r
