WHY IT NEEDS A POLICY

Why agent_handshake needs a policy

The name suggests an initialization or coordination action between agents, which could be a Read or Write operation, but without a description it's impossible to determine side effects. Given the server context (curated knowledge API, skill packs) and sibling tools, this likely performs some form of session/identity negotiation. With no description to confirm, confidence is low and Other is the safest classification.

From the tool's definition Tool name is 'agent_handshake'; description is empty or uninformative.
