+  --event-action="created"
+```

 ## Running Tests
 
 ### Prerequisites
 
-Install Node.js and npm, then install Jest:
+Install Python 3.11+ and uv for dependency management:
 
 ```bash
-npm install
+# Install uv (if not already installed)
+curl -LsSf https://astral.sh/uv/install.sh | sh
+
+# Install dependencies
+uv sync
 ```
 
 ### Test Commands
 
 ```bash
 # Run all tests
-npm test
-
-# Run tests in watch mode (reruns on file changes)
-npm test:watch
+uv run pytest
 
 # Run tests with coverage report
-npm test:coverage
+uv run pytest --cov=. --cov-report=html
+
+# Run tests in verbose mode
+uv run pytest -v
 ```
 
 ## Test Suite
 
 The test suite includes both unit tests and integration tests:
 
-### Unit Tests (`approval.test.js`)
+### Unit Tests (`test_approval.py`)
 
 Tests individual methods and functionality of the ApprovalManager class.
 
-### Integration Tests (`workflow-integration.test.js`)
+### Integration Tests (`test_workflow_integration.py`)
 
 End-to-end tests that simulate complete workflow scenarios as they would run in GitHub Actions.
