Describe the build in one prompt
Start with intent, not a parts list: "weekend canyon car, streetable, needs to handle first." BuildX takes the goal, the car, and the constraints, and turns them into a concrete plan instead of forty open browser tabs.
A staged, forkable plan
The output is a build plan in stages — what to do first, what depends on what, and where the money goes. Fork a plan to explore a different direction without losing the original; every version stays comparable.
Routed to the right tool
Each step dispatches to the tool built for it: calibration questions to TunerX, custom parts and looks to DesignX, fitment math to the calculators. BuildX is the orchestrator that keeps the project moving between them.
An orchestrator, not a replacement
BuildX doesn't redo what the other tools do — it sequences them. The plan lives in one place while the specialist tools do the deep work, so the build stays coherent from first idea to final bolt.
