WHY IT NEEDS A POLICY

Why invite_to_space needs a policy

Inviting members to a space is a reversible operation that modifies the collaboration structure and access permissions. While it affects user access and could have security implications if misused, it is not destructive (invitations can be revoked), does not move money, and does not execute arbitrary code. It falls under Write as it creates new collaborative relationships and modifies space membership.

From the tool's definition Tool name 'invite_to_space' and description indicate it adds new members to a space, which creates new access relationships in the system. Description states 'Owner/Admin権限が必要' (Owner/Admin permissions required), confirming it modifies collaborative access.
