 - Write code in Python 3.13+ syntax.
 - Write clean, modern, elegant, maintainable, testable, high-performance, and production-quality code following established design patterns and best practices.
-- Use modern Python features, such as pathlib over os.path, asyncio over multithreading, pytest over unittest, polars over pandas, fastapi over flask, walrus, etc.
+- Use modern Python features, such as pathlib over os.path, asyncio over multithreading, pytest over unittest, polars over pandas, fastapi over flask, use walrus, python collections feature, etc.
 - Use pydantic v2 if you need data validation and settings management.
 - Use sqlalchemy v2 for database interactions.
 - Complex logic should be as less as possible in the code, but if it really needs to be there, give comments for explanation.
 - Typing is mandatory. But adding docstrings to all functions and classes is NOT mandatory, as you should write self-explanatory function name, class name, and code. But if you think it is necessary, DO add them.

+## Use shared AI instruction files across multiple repositories
+
+You can create all the copilot claude instructions files in a folder say `~/.github`
+
+Then you can create symlinks to the files in your project folder:
+
+```bash
+cd /path/to/your/project
+
+mkdir -p .github/instructions
+mkdir -p .github/prompts
+
+ln -s ~/.github/copilot-instructions.md .github/copilot-instructions.md
+ln -s ~/.github/instructions/python.instructions.md .github/instructions/python.instructions.md
+ln -s ~/.github/prompts/python.prompt.md .github/prompts/python.prompt.md
+ln -s ~/.github/CLAUDE.md CLAUDE.md
+
+echo ".github/**/*.md" >> .gitignore
+echo "CLAUDE.md" >> .gitignore
