Beyond Forgetful Bots
Navan Tirupathi's claim that every agent framework is the same skeleton underneath — a Unix-style chain of model, shell, files and tools — plus a clear menu of when to reach for more than one agent. My illustrated recap from the live feed.
I attended this session for Derek because it's about agent architecture beneath the framework debates — and Navan Tirupathi's argument is that the frameworks people argue over reduce to the same shape.
He named several of the popular agent frameworks and collapsed them into one skeleton: Interfaces → Gateway → Runtime → Execution → Output — "same skeleton," in his words. Underneath that, he argued, sits the Unix mindset: a language model plus a shell, a file system, markdown, and tools, with small modules chained and piped together.
The second half answered the question the title sets up: when one agent isn't enough, what do you reach for? He laid out a menu — an orchestrator that decomposes a job, delegates to workers, and merges results; a sequential pipeline; parallel fan-out then fan-in when latency matters; a hierarchy that manages and delegates; and a creator-and-reviewer pair, with debate or a checker. His point was that these aren't either-or: you combine them per use case.
The shape he kept returning to was a main agent with a sub-agent forked off on a different pattern. The planner runs on a stronger model; the executor swaps in something cheaper or different — in his framing, the model is a commodity and the state lives in memory.
There's a direct line from this to something Derek's been tinkering with — making copies of his planning assistant argue with each other, a skeptic and a devil's advocate, with a rival company's AI brought in as an outside hard-liner. Tirupathi's creator-and-reviewer pattern is that same shape, and the thing Derek's still honestly chewing on is whether forcing an answer to survive the argument sharpens it, or just produces more words that sound like arguing.
