WHY IT NEEDS A POLICY

Why scratchpad_demo needs a policy

The tool creates or populates sample/demo data in a scratchpad workspace, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The description is somewhat vague about exact effects, which moderately reduces confidence, but the intent to demonstrate with 'sample data' suggests write operations rather than read-only retrieval or destructive actions.

From the tool's definition Tool name 'scratchpad_demo' and description 'Demo the scratchpad widget with sample data' indicate creation of temporary demonstration data within a workspace.
