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 | $0.00115 | $0.02781 |
| Sonnet 5 | $0.00046 | $0.01112 |
| Haiku 4.5 | $0.00023 | $0.00556 |
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 12d 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-agentis 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 ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

page-agent is a skill published in the GitHub repository tn5052/page-agent-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 231 tokens to every session and 5,562 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
