Placeholder write-up. Replace this body with the real account.
The problem
An agent that can only read text is blind to most of what a computer actually holds. One that can read everything runs out of context immediately.
The approach
Treat context as a managed resource rather than a buffer: extract entities agentically, summarise selectively, and retrieve from memory on demand, so the working set stays small while the addressable set does not.
What I would do differently
