A browser-based framework that lets users control a web page with natural-language instructions. It reads the page’s text and structure and uses an OpenAI-compatible language model to perform actions.

Use it to add natural-language controls to web applications, automate DOM-based page actions, and connect the page to a compatible language-model provider.

It lets a web page offer text-based automation without a separate automation server or screenshot analysis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00231	$0.05562
Opus 5.5	$0.00092	$0.02225
Sonnet 5.5	$0.00046	$0.01112
Haiku 4.5	$0.00023	$0.00556

Measured 2mo ago against content hash c2b846349717, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

page-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Alibaba PageAgent — Client-Side GUI Agent Framework

Auto-activation: This skill activates when page-agent is detected in project dependencies or when implementing natural language web automation.

What is PageAgent?

PageAgent is a purely client-side web automation framework powered by LLMs. It converts natural language commands into DOM operations through an iterative Re-act (Reasoning + Acting) loop. Unlike server-side tools (Selenium, Playwright) or screenshot-based approaches, PageAgent:

Runs entirely within the webpage as JavaScript code
Uses text-based DOM analysis (no screenshots, no vision models)
Requires zero backend infrastructure
Supports any OpenAI-compatible LLM provider

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
