How Rootshift works.
Rootshift is the delivery system Rootstrap uses to build its clients’ products. You get it by working with Rootstrap. These guides explain what it is, how it works, and what it replaces.
- What is Rootshift?
Rootshift is the AI-native software delivery system Rootstrap uses to build its clients' products: a validated Ground Truth of the business, a fleet of agents that build and review against it, gates that refuse unverified work, and a record of every run.
- What is a Ground Truth?
A Ground Truth is a versioned, structured, owned, and validated model of how a business works, in seven parts, precise enough that a person and an AI agent can both build against it and verify against it.
- Ground Truth vs spec-driven development
Spec-driven development gives AI agents a spec; context engineering decides what an agent sees. A Ground Truth adds what both leave out: who says it is true, whether it was approved, and what happens when two sources disagree.
- What replaces Agile and Scrum
Agile and Scrum rationed one scarce thing, engineering hours. Agents removed that scarcity, so Rootshift deprecates them. Here is what replaces each one: Ground Truth, capabilities, delivery loops, evals and gates, and the record.

Definitions of the terms Rootshift uses: Ground Truth, capability, open decision, builder brief, fresh-context builder, independent review, gates, evidence class, the record, and the operator.
- Why AI-native delivery needs a shared Ground Truth
The foundational essay. Agile solved a problem that no longer exists; a real takeover, six weeks in, and the seven-part Ground Truth that holds it together.
