WHY IT NEEDS A POLICY

Why generate-frontend-client needs a policy

This tool generates client-side code artifacts. Code generation is a write operation because it creates new files/output that modify the project structure. However, the severity is low because: (1) the generated code is not executed by the tool itself, merely produced as an artifact; (2) it has no direct side effects on running systems or data; (3) reversal is trivial (delete generated files).

From the tool's definition The tool description indicates it 'Generate[s] a TypeScript client' which is a code generation operation. The tool creates (writes) new TypeScript client code that will be consumed by frontend applications.
