# Mango.Nop Libraries — Claude Code Instructions Before writing any code, read these files: 1. `.github/copilot-instructions.md` — Domain rules (single source of truth) 2. `docs/GLOSSARY.md` — Entity/DTO, data access, and service terminology 3. The relevant project's `README.md` for folder-specific context These libraries depend on **AyCode.Core** (DLL references — see HintPaths in .csproj for relative location). When a type is referenced but not defined here (e.g. `IEntityInt`, `IAcLoggerBase`, `AcBinarySerializer`, `ToonDescription`), look it up in AyCode.Core source. For core framework rules see `../AyCode.Core/CLAUDE.md`. When modifying code, update the corresponding README.md if it becomes out of sync with the code.
