+# Pre-commit Configuration for Code Quality Management
+# =================================================
+#
+# This configuration establishes automated code quality checks that run at different
+# git hook stages. It ensures consistent code style, identifies potential security
+# issues, and maintains high code quality standards across the project.
+#
+# Installation and Usage
+# ---------------------
+# 1. Install pre-commit in your development environment:
+#    pip install pre-commit
+#
+# 2. Install the git hooks:
+#    pre-commit install
+#
+# 3. To run all checks manually:
+#    pre-commit run --all-files
+
+# Default hook types installed by 'pre-commit install'
+default_install_hook_types:
+  - pre-commit
+
+# Specify the Python version for consistency across a team
+default_language_version:
+  python: python3.12
+

+  # Standard Pre-commit Hooks
