Vault Agent allows client-side caching of tokens and leases. If the agent is shut down, those tokens and leases cached will be revoked.

The statement is false; Vault Agent manages tokens and leases to improve performance and reliability, but its shutdown does not trigger automatic revocation of those credentials on the Vault server.

Vault Agent's primary function includes caching and automatic renewal of tokens and leases; if the agent shuts down, the cached tokens and leases are not automatically revoked by Vault but remain valid on the Vault server until their natural expiration or explicit revocation.
