WHY IT NEEDS A POLICY

Why generate-test-cases needs a policy

Based on the tool name and server context (Playwright-based UI and API testing with test case generation from requirements or API specs), this tool likely generates/creates test case files. With no description to confirm, the most reasonable inference is Write (creates test files). Confidence is low due to empty description. Could be Read if it only previews/returns test cases without saving them.
