WHY IT NEEDS A POLICY

Why create_agent_wallet needs a policy

This tool creates new cryptographic wallet infrastructure that will be used for trading. While not irreversible (wallets can be revoked), it establishes persistent signing authority and commits the user to a new trading relationship. It spans Write and Execute: the state change (wallet creation) and authorization flow are Write-category side effects.

From the tool's definition Tool description explicitly states 'Create a new Pear Protocol agent wallet' and 'executes a state change.' This is wallet creation that modifies the user's trading infrastructure and requires subsequent user approval on Hyperliquid.
