WHY IT NEEDS A POLICY

Why imap_apply_sorting_rules needs a policy

Applying sorting rules modifies email organization state reversibly (emails can be re-sorted or rules removed), making this a Write operation rather than a Read operation. While not destructive or financial, misuse could result in email misorganization affecting multiple accounts. Confidence is moderate (0.75) because the tool description is empty, requiring inference from the tool name and server capabilities.

From the tool's definition Tool name 'imap_apply_sorting_rules' indicates modification of email organization rules; server description states the wrapper 'enables users to read, search, and send emails' and 'supports secure AES-256 encryption,' suggesting state-changing operations.
