WHY IT NEEDS A POLICY

Why add_variable needs a policy

This tool performs reversible data creation and modification (Write category). Severity is medium because unintended variable additions or replacements in a script editor could break script logic or introduce unintended behaviors, but changes are reversible through additional edits and do not cause permanent deletion or financial impact.

From the tool's definition add_variable allows creating or modifying variables within the 247afk block editor. The description explicitly states it can 'Add a new variable or replace an existing one', which are create and update operations.
