agent.budget.create

Spawn a child agent with a scoped multisig sub-vault and a policy envelope.

Spawn a child agent with a scoped multisig sub-vault and a policy envelope. The operation depends on the configured provisioning saga. Check whether the result is draft or active; a failure does not establish that every partial resource has been removed.
