WHY IT NEEDS A POLICY

Why edit_script needs a policy

This tool modifies existing data (script files) reversibly through replacement/overwriting. While reversible (prior versions could theoretically be recovered), the scope is high because altered scripts can introduce bugs, security vulnerabilities, or break game functionality.

From the tool's definition Tool description states it 'Edit an existing GDScript file by replacing its content' — this is a direct modification operation that changes the content of a source file.
