SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

page-agent helps you turn a complex web UI into something users can drive with plain natural language, without rewriting your frontend.

Core Features & Use Cases

  • In-page GUI agent: Reads the current page’s DOM as text and executes instructions like “click login and fill username as John”.
  • Single-script / npm embed: Ship as a single <script> tag for a quick demo or install it via npm for production.
  • LLM-backed DOM actions: Uses an OpenAI-compatible /v1/chat/completions endpoint to decide what DOM actions to take.

Example: Add an AI “copilot” to your admin panel so users can request tasks like “create an invoice for Acme Corp and email it” instead of clicking through multiple screens.

Quick Start

Tell an AI assistant to “Load the page-agent panel on this page, then click the login button and fill the username field with John.”

Frequently Asked Questions about page-agent

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add a natural language AI copilot to an existing web UI?

To add a natural language copilot to a web UI, embed a script or npm package that reads the DOM as text and translates instructions into executable actions. This allows users to control page elements without rewriting the frontend.

Can I automate DOM actions without browser extensions or screenshots?

Yes, you can automate DOM actions without extensions by converting live page structure into text for an LLM. The model processes the DOM directly to decide and execute operations, bypassing the need for visual screenshots.

Do I need an OpenAI-compatible API endpoint to drive browser agent interactions?

Yes, driving browser agent interactions requires an OpenAI-compatible chat-completions endpoint. You must configure the baseURL, model, and API key to reliably process DOM structure and execute UI actions.

How does a DOM automation agent handle complex multi-step admin tasks?

A DOM automation agent handles complex admin tasks by reading the page structure and issuing sequential executable UI actions. Users can request multi-step operations like creating invoices, which the agent executes by interacting with elements.

What is the best way to modernize legacy UIs for natural language control?

The best way to modernize legacy UIs for natural language control is embedding an in-page agent that translates text instructions into DOM operations. This avoids a complete frontend rewrite while adding conversational task execution.

Can I evaluate LLMs against DOM-based interaction scenarios?

Yes, you can evaluate LLMs against DOM-based interaction scenarios by providing the model with page structure as text. The agent executes actions based on the model's output, allowing assessment of its ability to navigate interfaces.
