What we write about
Four threads, one voice.
Engineering
Architecture, planner, MCPs, agents. How the executor really works, why the planner is the model it is, what bring-your-own MCP looks like when it ships.
The world of agents
Essays from Agents City. Charter-level thinking, the economy of Flows, what we believe comes after the chatbot era.
Lessons
Founder reflections. What worked, what we burned, what we'd do differently.
