WHY IT NEEDS A POLICY

Why share_form needs a policy

This tool creates a new artifact (a sharing URL) that persists and modifies the state of the system by enabling form data collection. It is reversible (URLs can be disabled/deleted) and has a write-like effect. Severity is medium because the blast radius is limited—misuse primarily affects form sharing and data collection workflows rather than financial operations or irreversible deletions.

From the tool's definition Tool description states it 'Creates an unique sharing URL to collect form data' — a create operation that generates a new shareable resource and enables data collection.
