Users migrating from Cursor to Claude Code may encounter issues as Claude Code does not support Cursor's rule system. Cursor utilizes `.cursorrules` and `.cursor/rules/*.mdc` files, which include glob matching and conditional application. In contrast, Claude Code relies on a single `CLAUDE.md` file where rules are plain Markdown sections. Migrating requires translating Cursor's glob-based and conditional rules into Claude Code's simpler, context-based instruction format, often necessitating shorter, more absolute phrasing to ensure the AI adheres to them.
