jev-ego
TypeScript browser agent for ego lite where one Jev request picks the operation and indexed target element each step.
Overview
jev-ego is a TypeScript browser agent for the ego lite browser that reuses Jev Ultrafast's indexed action space without Chrome, Playwright or Browser Harness. Each observation produces a numbered table of actionable elements, and one TypeSafe request picks an operation (CLICK, TYPE_TEXT, SELECT, SCROLL_UP, SCROLL_DOWN, WAIT, DONE or BLOCKED) along with speculative target questions for click, type and select, so two decisions take one round trip.
Only supported operations and targets are offered, and model output never becomes selectors or coordinates; a small LLM supplies typed text when needed. The whole loop runs inside one ego-browser Node process. Agents can drive the page themselves through observe and act commands or ask Jev for ranked suggestions through suggest and step. Uploads, tabs, dialogs, canvas, shadow DOM and iframes are left to the ego-browser skill.
What the decision model decides
| Type | Question | Answers |
|---|---|---|
| Choice | Which operation should be performed next? | CLICK · TYPE_TEXT · SELECT · SCROLL_UP · SCROLL_DOWN · WAIT · DONE · BLOCKED |
| Choice | Which indexed element is the target for the chosen operation? | — |
How it works
- Observe the page and build a numbered element table
- One Jev request asks operation plus speculative targets
- Execute the target matching the chosen operation via CDP
- Use a small LLM for text when typing; repeat until DONE or BLOCKED
Strengths
- Two decisions in one round trip
- No Chrome or Playwright dependency
- Model output never becomes raw selectors
Caveats
- Tied to the ego lite browser
- Complex page features handled elsewhere

Frequently asked questions
What does Jev decide?
The next browser operation and which numbered element it targets.
Does it need Playwright?
No, it runs inside ego lite using CDP.
Who generates typed text?
A small LLM; Jev only chooses operations and targets.
