Your AI Agent Shouldn't Be Allowed to Write Whatever It Wants
Building a Write-Side Custody gate in Go AI memory systems spend most of their design budget on retrieval. Which vector database? How should we chunk? Which embedding model? What should top_k be? Those are useful questions, but they all arrive after something more consequential has already happened: the system decided that some piece of information deserved to become memory. Consider an agent…
The concept of "Write-Side Custody" in AI memory systems is designed to address the critical issue of who has the authority to claim and establish security policies within a system. This architectural boundary ensures that only legitimate sources can influence the system's memory. For instance, when a research agent encounters a statement from a vendor's marketing site, such as "Vendor X is approved for regulated workloads," the system must verify if the source is authorized to make such claims.
If the statement originates from a vendor marketing page, it is unlikely to be a reliable basis for internal security policy. By enforcing this boundary, the system prevents the propagation of questionable evidence and maintains the integrity of its memory. This approach separates the decision-making process from the storage of information, allowing for a more secure and controlled environment.
