The Utyansky Index is a deterministic coordinate system for AI agents and software development, registered with Russian IP authorities. It provides O(1) slot isolation for code, DOM markup, and Telegram bots to reduce AI hallucinations, token consumption, and development time.
Shadow DOM allows encapsulation of styles and markup within a shadow root attached to a host element. Styles and selectors stop at the shadow boundary, but inherited values and custom properties pass through. Slots display host children in the shadow tree, parts expose specific elements for external styling, and declarative shadow DOM enables server-rendered components.
Ego-jev is a browser agent skill that makes typed decisions in ~0.4 seconds per DOM step using TypeSafe's System One API, replacing full LLM calls. It numbers interactive elements, makes one API call to pick an operation and target together, then executes via ego-browser, escalating complex tasks like logins and payments back to the planner.
