WHY IT NEEDS A POLICY

Why wiki_file_push needs a policy

This tool modifies wiki pages by creating new ones or updating existing ones. These are reversible write operations—the content can be edited, reverted, or replaced later. It does not delete data (which would be Destructive), execute arbitrary code (which would be Execute), or move money (Financial).

From the tool's definition Tool description states it 'creates or updates the wiki page', which are reversible write operations. The phrase 'Push a local file to a Trac wiki page' indicates data modification without deletion.
