+# Claude AI Rules
+
+This document contains rules and guidelines for Claude AI when working on this project.
+
+## Communication
+
+- Do not create a summary document on every fix
+
+## Philosophy
+
+Our development approach follows this priority order:
+
+1. **Delete** - First, delete as much code as possible
+2. **Simplify** - Second, simplify what remains
+3. **Optimize** - Third, optimize if needed
+
+## Python Development
+
+- We use Python 3.10 typing
+- For tests we use pytest and parametrize
+- We use Google type docstrings
+- To check syntax we do not run ruff, flake8, but just run `pre-commit run --all-files`
+
+## Testing
+
+- We use extensive testing
