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 | $0.00039 | $0.01034 |
| Opus 5.5 | $0.00016 | $0.00414 |
| Sonnet 5.5 | $0.00008 | $0.00207 |
| Haiku 4.5 | $0.00004 | $0.00103 |
Grade A, and why
browser-scrape 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
浏览器抓取技能(AutoCLI)
复用用户本机 Chrome 的登录态抓取需要登录的站点(推特/X、知乎、Bilibili、Reddit、小红书等 55+ 平台)。不需要 cookie 配置、不需要 API key。
前置要求(由用户完成一次即可)
- 安装 AutoCLI Rust 二进制:参见 https://github.com/nashsu/AutoCLI(单文件 ~4.7MB,无运行时依赖)
- 装 autocli Chrome 扩展(仓库 README 里有下载链接和加载步骤)
- 保持 Chrome 运行并在目标站点处于登录态
autocli doctor应报告OK
如果 autocli doctor 失败,先提醒用户修复前置条件,不要继续抓取。
能力范围
AutoCLI 在 Prax 里通过普通 Bash 工具调用——它不是 MCP server,只是一个 CLI。只要 PATH 里能找到 autocli,任何 Prax agent 都能用。
常用命令(按频次排序)
# 诊断(第一次使用必跑)
autocli doctor
# 推特/X
autocli twitter timeline --limit 20 --format json
autocli twitter search --query "AI safety" --limit 10 --format json
# 知乎
autocli zhihu hot --limit 20 --format json
# Bilibili
autocli bilibili hot --limit 10 --format json
# Reddit
autocli reddit subreddit --name "MachineLearning" --limit 15 --format json
# 任意网页文章(不走登录态)
autocli read https://example.com/article --format md
autocli read https://example.com/article --format text -o /tmp/article.txt
--format json|md|text|yaml|csv任选;编程任务优先json,归档任务用md--limit N控制条数autocli --help查所有子命令;单平台用autocli twitter --help
典型抓取流程
用户让我"抓今天 X 上 AI 相关点赞 top 10 存到 Obsidian",我的动作:
autocli doctor确认前置条件autocli twitter timeline --limit 50 --format json拉最近推文- 本地过滤(按关键词/点赞数),用 Write 工具存到
.prax/vault/ai-news-hub/YYYY-MM-DD/下 - 每条一个 markdown 文件,header 带
tweet_id / author / likes / url / scraped_at - 完成后总结文件路径给用户
产出约定(配合 knowledge-compile 技能)
- 目录命名:
.prax/vault/<topic>/YYYY-MM-DD/(方便 Obsidian 按日期归档) - 文件命名:
<source>-<id>.md,例如twitter-17xxx.md - 文件 frontmatter:至少包含
source / url / scraped_at,供下游knowledge-compile编译 wiki 用 - 原始 JSON 保留:把
autocli ... --format json的原始输出同步存一份到raw/<source>-<stamp>.json,便于溯源
边界与禁区
- 不要用 AutoCLI 做 写操作(发帖/点赞/关注)除非用户明确要求;无脑批量操作会导致账号封禁
- 不要把登录 cookie 或扩展私钥外传
- 被站点频控或返回异常时先停下来报告,不要循环重试——可能会触发风控

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.
- 1mo ago First seen · 83 lines · 39 tokens per session scan A 42866d05a5f5
browser-scrape is a skill published in the GitHub repository ChanningLua/prax-agent (272 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 1,034 once invoked, about $0.0002 per session on Opus 5.5. 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.
