WHAT IT DOES

What unrepostPost does on Xdevplatform/xmcp

WHY IT NEEDS A POLICY

Why unrepostPost needs a policy

This tool modifies data by undoing a repost action, which is a reversible write operation. It is not destructive because unreposting can be reversed by reposting. It is not execute or financial in nature. While the blast radius is limited to the user's own repost state, the ability to modify content sharing state warrants medium severity.

From the tool's definition The tool 'unrepostPost' performs a reversal action—removing a repost—which modifies the state of social media content. The operation is reversible (a user can repost again), distinguishing it from permanent deletion.
