WHY IT NEEDS A POLICY

Why clio_update_matter needs a policy

PATCH is a partial update operation that modifies existing matter data reversibly. It does not delete or create records, and there is no financial transaction involved. Misuse could alter legal matter details (status, billing info, assigned attorneys), which has moderate blast radius in a law firm context.

From the tool's definition PATCH a matter. Pass only the fields you want to change.
