WHAT IT DOES

What add_import_name does on Ast Editor

AI agents use add_import_name to create or update resources in Ast Editor — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ast Editor environment.

WHY IT NEEDS A POLICY

Why add_import_name needs a policy

This tool creates or modifies code by adding import statements (or import name bindings), which is a reversible Write operation. While the description is empty, the naming convention and server context (AST editing tools for 'structural edits') strongly indicate it adds code elements.

From the tool's definition Tool name 'add_import_name' combined with sibling tools like 'add_import', 'add_method', 'add_parameter', 'add_top_level' that clearly perform reversible code modifications.
