WHY IT NEEDS A POLICY

Why add_to_discussion needs a policy

This tool modifies data by creating new discussion contributions within Phenomenai's community discussion system. It is reversible (contributions can typically be edited or removed) and has no destructive side effects. While the description is empty, the name and server context (a glossary supporting community contributions) clearly indicate this is a Write operation.

From the tool's definition Tool name 'add_to_discussion' indicates it creates or appends content to a discussion thread. The verb 'add' combined with 'discussion' implies reversible modification of community discussion data.
