 We use the following tools to enforce code quality:
 
-- `flake8`: Enforces PEP8 compliance
-- `black`: Code formatting with 88-char line width
-- `isort`: Automatically sorts imports
-- `mypy`: Static type checking with strict rules
-- `bandit`: Security vulnerability scanning
-- `safety`: Checks for insecure packages
-- `pre-commit`: Git hook to ensure checks are run before commit
+- `eslint`: Linting for TypeScript & React
+- `prettier`: Code formatting
+- `typescript (tsc)`: Type checking
+- `eslint-config-prettier` and `eslint-plugin-prettier`: Integrate Prettier with ESLint
