There is a shortfall to our current approach to agent memory. Right now, we are just collecting flat facts across a flat memory surface and creating vectorized chains of ambiguity, then wondering why when we ask an agent why it did something the best answer we can get is a probabilistic half-hallucinated half-answer that does not address the actual details of the issue, because it is simply pattern matching to find untyped similarities.

So I built FlowScript.

FlowScript is a typed reasoning graph that your agent builds through tool calls during your everyday work. It is NOT a graph database. What it is is a small set of unique opinionated primitives: things like thoughts, questions, decisions, blockers, and each of those have typed relationships between them. Your agent calls the tools as it works and it builds this typed graph, and then afterwards you can query that structure to get actual deterministic answers using five queries: tensions, blocked, why, whatIf, alternatives.

What does this look like in practice? Here's an agent that has been reasoning about database choices for a few sessions:

  > mem.query.why("node_postgres_decision")

  PostgreSQL chosen
      ← "Need ACID for payment processing"
      ← "Original requirement: handle refunds atomically"
      ← "Stripe webhook failures in staging revealed race condition"

  > mem.query.tensions()

  ><[performance vs cost]
      "Redis: sub-ms reads critical for UX" vs "Redis cluster: $200/mo for 3 nodes"

The why chain traces back to the original constraint and the tension preserves the actual tradeoff being made. These are things no vector store can do, because they are NOT just flat facts, but are relationships and reasoning chains that are being captured in a deterministic way. Meaning you can actually go back and audit the actual reasoning of your agent, how it evolved over time, and see the actual tensions that were being balanced. No more opaque reasoning that is lost as soon as the polished answer is generated. Try that in any other memory system, I'll wait.

Other memory systems, when they come across a tension or a contradiction, for the most part they are just simply deleting that. And that is wrong because that tension is new knowledge. Knowledge that we need to actually keep for auditing and because it tells us about the evolution of the system and its cognition over time. So instead of deleting contradictions, we relate and create named relationships for them. Relationships you can query.

Every decision, every tension, every piece of reasoning is being deterministically captured into an audit trail and hash-encoded. Now, not only do you have a deterministic reasoning chain, but that reasoning chain is auditable. You can go back to any point within the time that you have audit logs for and deterministically review and understand the actual reasoning chain that your model was using. Something that no other system can offer. The EU AI Act is going to require exactly this kind of transparency by August 2026, and as far as I can tell, FlowScript is the first open source agent memory system that is designed to meet that bar.
