WHY IT NEEDS A POLICY

Why generate_tests needs a policy

This tool creates test code artifacts for a codebase. It modifies the test suite by generating new test files, which is a Write operation (creates data reversibly). It does not execute arbitrary code in production, delete existing data, or trigger financial operations.

From the tool's definition Tool description states 'Gera suite de testes JUnit5/Mockito compilável' (Generates compilable JUnit5/Mockito test suite) - this creates new test files/code artifacts.
