Why I Built xAgent
I started building xAgent in April 2025.
The original idea was straightforward: build a task-oriented Agent that could run work on its own and turn AI into real automation. Looking back, that sentence sounds simple. Most of what I have done over the past year has been filling in everything hidden inside the words “run work on its own.”
The first version used a single Agent. I quickly ran into a problem: once the prompt focused its attention on one kind of work, the Agent could do that work well but handle other tasks terribly. Fix one side and it would forget the other. Ask it to pay attention to everything and it would end up paying proper attention to nothing.
That led me to multiple Agents, each responsible for a different part of the work and able to collaborate with the others. The idea worked, but as soon as they started running together, the next problem became obvious: tokens were too expensive.
