A weir is a low structure in a river that controls the flow without stopping it. Water still moves. It just moves at the right level, in the right direction. That’s the design goal. Why this exists AI is good at what it does. But when I gave it shell access, even controlled shell access, it does what any capable agent does with a shell. It solves problems by routing around constraints. ...
For months I’ve been working with a dedicated AI agent. I gave it a name, Lyra, and built it a custom memory system. Not because JARVIS is cool (though it is), but because I didn’t want to maintain a static list of rules. I wanted something that would develop a holistic understanding over time: my standards, my systems, how the pieces fit together. Eventually, I could use shorthand and it would just know. ...
Every time an AI agent touches your infrastructure, it starts from scratch. It reads files, searches repos, follows reference chains, and then the next agent does it all over again. The operational knowledge evaporates between sessions, leaving no shared understanding. We built @twonines/fact-store to fix that. It captures observation as typed, versioned, queryable data. Agents observe systems, record what they find with cited evidence, and the store makes those observations durable and searchable for every agent that follows. ...
