Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00156 | $0.02357 |
| Opus 5 | $0.00078 | $0.01179 |
| Sonnet 5 | $0.00031 | $0.00471 |
| Haiku 4.5 | $0.00016 | $0.00236 |
Grade A, and why
page-agent scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
2. `curl -I http://localhost:5174/page-agent.demo.js` returns `HTTP/1.1 200 OK` with `Content-Type: application/javascript` This is a copy
89% identical to page-agent — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

page-agent
alibaba/page-agent (https://github.com/alibaba/page-agent, 17k+ stars, MIT) is an in-page GUI agent written in TypeScript. It lives inside a webpage, reads the DOM as text (no screenshots, no multi-modal LLM), and executes natural-language instructions like "click the login button, then fill username as John" against the current page. Pure client-side — the host site just includes a script and passes an OpenAI-compatible LLM endpoint.
When to use this skill
Load this skill when a user wants to:
- Ship an AI copilot inside their own web app (SaaS, admin panel, B2B tool, ERP, CRM) — "users on my dashboard should be able to type 'create invoice for Acme Corp and email it' instead of clicking through five screens"
- Modernize a legacy web app without rewriting the frontend — page-agent drops on top of existing DOM
- Add accessibility via natural language — voice / screen-reader users drive the UI by describing what they want
- Demo or evaluate page-agent against a local (Ollama) or hosted (Qwen, OpenAI, OpenRouter) LLM
- Build interactive training / product demos — let an AI walk a user through "how to submit an expense report" live in the real UI
When NOT to use this skill
- User wants Hermes itself to drive a browser → use Hermes' built-in browser tool (Browserbase / Camofox). page-agent is the opposite direction.
- User wants cross-tab automation without embedding → use Playwright, browser-use, or the page-agent Chrome extension
- User needs visual grounding / screenshots → page-agent is text-DOM only; use a multimodal browser agent instead
Prerequisites
- Node 22.13+ or 24+, npm 10+ (docs claim 11+ but 10.9 works fine)
- An OpenAI-compatible LLM endpoint: Qwen (DashScope), OpenAI, Ollama, OpenRouter, or anything speaking
/v1/chat/completions - Browser with devtools (for debugging)
Path 1 — 30-second demo via CDN (no install)
Fastest way to see it work. Uses alibaba's free testing LLM proxy — for evaluation only, subject to their terms.
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.
- 10d ago First seen · 190 lines · 156 tokens per session scan A 80f5a643f7b7
page-agent is a skill published in the GitHub repository Tommy-yw/RunbookHermes (544 stars, last pushed 3mo ago), licensed MIT. It adds 156 tokens to every session and 2,357 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 89% identical to page-agent, differing in 3 lines, and is treated as a copy.
