Dev.to Machine Learning
About This Tutorial
Claude Code's CLAUDE.md enforces project rules, unlike Cursor's legacy.cursorrules. Structure with alwaysApply: true and split by domain. What Changed - The Legacy of.cursorrules and Claude Code's Approach Cursor's.cursorrules file is silently ignored in Agent Mode. But if you're migrating from Cursor, you need to know: CLAUDE.md is the only way to enforce rules in Claude Code's agentic workflows. Cursor's.cursorrules works in standard chat but not in Agent Mode. The newer system uses.cursor/rules/*.mdc files with YAML frontmatter.
