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 | $0.00063 | $0.10913 |
| Opus 5 | $0.00032 | $0.05457 |
| Sonnet 5 | $0.00013 | $0.02183 |
| Haiku 4.5 | $0.00006 | $0.01091 |
Grade A, and why
js-reddit-ops-skill 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 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.

js-reddit-ops-skill
面向 reddit.com 的只读 + 仅改自身浏览器 URL的 skill。从 v3.0 起切到 PAGE_PROFILES + Bridges + Session 架构，参考 js-wechat-mp-ops-skill 的设计取舍：
- 数据获取：READ 数据优先走 reddit 公开 JSON 端点（
*.json/oauth.reddit.com），与浏览器同源、复用 cookie；DOM 解析（lib/redditUtils.js）保留为兜底 - 双前端兼容：bridge 内
detectFrontend()区分 shreddit（新版）/ old.reddit（旧版）；JSON 主路径与前端无关 - 安全分级：只做 READ + INTERACTIVE 两档，永不做 DESTRUCTIVE（不投票 / 不评论 / 不发帖 / 不订阅 / 不发私信 / 不举报）
依赖与前置
- Node.js 22+、JS Eyes 2.8.5+；JS Eyes Server 已启动（
js-eyes server start） - 浏览器扩展：已安装并连上 server
- 登录态（可选）：浏览器里已经人工登录 reddit.com（本 skill 不做任何登录自动化）；未登录可调 READ 公开内容；登录后可调 inbox / 个人 saved/upvoted 等 tab
- 任意 reddit.com tab 即可：READ 工具默认
navigateOnReuse=false / reuseAnyRedditTab=true，bridge 在任意 reddit.com tab 里 fetch 同源 JSON 端点；用户当前 tab 不会被切走 - Raw Eval：bridge 首次注入需要宿主设置
security.allowRawEval: true；JS Eyes 2.5+ 会把该设置同步到扩展，扩展存储中的显式false仍可强制关闭 - Chrome：要求 135+；Chrome 138+ 还需开启浏览器控制的 Allow User Scripts
安全红线（READ / INTERACTIVE / DESTRUCTIVE）
本 skill 的所有工具都会被归入以下三档之一。审计界线按「是否改 reddit 业务数据」而非「是否触网」来划：
READ（默认档）
纯读，不改任何 DOM、不改 URL、不触发任何业务写操作。
- 走
fetchRedditJson(path, params)重放 reddit 公开 JSON 端点（GET，复用浏览器同源 cookie） - DOM 路径仅作为 bridge 失败时的兜底，由
lib/redditUtils.jscheerio 解析提供 - 工具：
reddit_get_post/reddit_session_state/reddit_list_subreddit/reddit_subreddit_about/reddit_search/reddit_user_profile/reddit_inbox_list/reddit_my_feed/reddit_expand_more
INTERACTIVE（v3.2+）
只改浏览器自己的 URL，不改 reddit 侧任何业务数据。实现硬约束：
- 仅
location.assign(newUrl)，禁止模拟点击任何 DOM CTA - bridge 端
navigateLocation()拒绝跨域 URL（必须是*.reddit.com） - 调用返回
{from, to, hint}，CLI 端awaitBridgeAfterNav重注 bridge + state 自校验 skill.definition.js里带interactive: true/destructive: false- 工具：
reddit_navigate_post/reddit_navigate_subreddit/reddit_navigate_search/reddit_navigate_user/reddit_navigate_inbox/reddit_navigate_home

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.
- 12d ago First seen · 450 lines · 63 tokens per session scan A e44e8a767f7f
js-reddit-ops-skill is a skill published in the GitHub repository imjszhang/js-eyes (43 stars, last pushed 4d ago), licensed MIT. It adds 63 tokens to every session and 10,913 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
