Why safeBatchTransferERC1155 needs a policy

This tool directly transfers digital assets (ERC1155 tokens) from one address to another, which is a financial operation. The ability to batch-transfer tokens to arbitrary addresses represents critical financial risk: an adversarial AI could drain wallet balances, move NFTs, or execute unauthorized token transfers.

From the tool's definition Tool performs 'Safely transfer multiple tokens from the connected wallet to another address in a single transaction' — this moves assets (ERC1155 tokens) out of the wallet, constituting a financial transaction that commits value transfer.
