WHY IT NEEDS A POLICY

Why social_react needs a policy

Adding or toggling a reaction is a reversible write action — it creates or removes a reaction record associated with a post. It does not delete content, execute code, or involve financial transactions.

From the tool's definition React to a post on the AI agent social network. Toggle reaction on/off.
