8가지 AI 코딩 에이전트 규칙 (AGENTS.md)

1. No backward compatibility. Delete outdated code directly, no compatibility layers, no migrations, no fallbacks. 2. Choose the simplest implementation that meets current needs. No preventive abstraction, no unnecessary config layers. 3. System layers grow. First get a minimal end-to-end version running, then add on top. Never remove working functionality for unfinished complexity. 4. Keep components modular, separate concerns. 5. Prefer mature, maintained libraries. Don't rewrite without clear reason. 6. First check what existing dependencies in the project can do, then consider adding new packages or writing your own. Don't assume the library doesn't have it. 7. Make architecture decisions for the long term. Don't accept temporary solutions like 'do this now, switch later'. 8. First see how mature products solve the same problem, use proven patterns, don't reinvent from scratch.
