WHY IT NEEDS A POLICY

Why set-withdrawal-address needs a policy

This tool writes/modifies blockchain state by changing where delegation rewards are directed, which is a Write-category action (reversible configuration update). It is not destructive since the change can be undone by setting a different address. Severity is medium because while it doesn't directly move funds, misconfiguration could redirect rewards to an unintended address, creating financial exposure.

From the tool's definition Tool name 'set-withdrawal-address' and description 'Set reward withdrawal address for delegation rewards' indicate the tool modifies account configuration on the Osmosis blockchain.
