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.

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 | $0.00052 | $0.00863 |
| Opus 5 | $0.00026 | $0.00432 |
| Sonnet 5 | $0.00010 | $0.00173 |
| Haiku 4.5 | $0.00005 | $0.00086 |
Grade A, and why
js-hn-ops-skill 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 11d 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.
What it actually says
js-hn-ops-skill
面向 news.ycombinator.com 的只读 + 仅改自身浏览器 URL skill，架构对齐 js-reddit-ops-skill / js-x-ops-skill：
- 数据获取：READ 优先走 Firebase 公开 API（
hacker-news.firebaseio.com/v0）与 Algolia（hn.algolia.com）；DOM 解析为兜底 - 安全分级：READ + INTERACTIVE 两档，永不 DESTRUCTIVE（不投票 / 不评论 / 不 submit）
依赖与前置
- Node.js 22+、JS Eyes 2.8.5+；JS Eyes Server 已启动且浏览器扩展已连接
- 宿主设置
security.allowRawEval: true以允许 bridge 注入；JS Eyes 2.5+ 会同步到扩展，扩展侧显式false仅作为强制关闭覆盖 - Chrome 要求 135+；Chrome 138+ 还需开启浏览器控制的 Allow User Scripts

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.
- 11d ago First seen · 84 lines · 52 tokens per session scan A a199c49217f2
js-hn-ops-skill is a skill published in the GitHub repository imjszhang/js-eyes (43 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 863 once invoked, about $0.0003 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 2026-08-30.
