WHAT IT DOES

What batch_apply_template does on Solidworks

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

WHY IT NEEDS A POLICY

Why batch_apply_template needs a policy

The tool modifies drawing files by applying templates to them. This constitutes a Write operation as it creates or updates data (drawing properties/formatting) in a reversible manner. The blast radius is medium because it affects multiple files at once, but the operation is not destructive (templates can be reapplied or reverted) and does not involve irreversible deletion, code execution, or financial operations.

From the tool's definition Tool applies templates to multiple drawing files, modifying their properties and formatting. This is a reversible modification operation affecting multiple files.
