What it does
Site Cookie Login is an agent skill from bifrost-proxy/bifrost. Open a target website, wait for user login, verify login with required cookies plus an HTTP probe, and save cookies into .env for later automation. Use this when a site needs controlled browser login, cookie persistence, and automatic login-state checks.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/config.template.json`, `scripts/package-lock.json` and `scripts/package.json`).
The repository describes itself as: Bifrost 是一个用 Rust 编写的高性能、AI 友好的代理服务器，它提供强大的请求拦截、修改和规则配置能力，支持 TLS 解密、脚本扩展等高级功能，支持强大的模糊搜索，支持导入导出分享，支持一键重放请求，支持Coding Agent 自主管理。提供类似 postman 的请求管理和验证能力，无缝和代理能力集成。 The licence is MIT.

Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit e8ed138. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 4 files in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
npmnode
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Site Cookie Login loads about 600 tokens when it runs, and up to ~753 if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 175 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

- description
- Open a target website, wait for user login, verify login with required cookies plus an HTTP probe, and save cookies into .env for later automation. Use this when a site needs controlled browser login, cookie persistence, and automatic login-state checks.
Site Cookie Login
通用的「浏览器登录 → 抓 Cookie → 校验登录态 → 持久化」能力，可接入任意需要浏览器登录的站点。
适用场景
- 目标站点不提供 API Token，只能通过浏览器登录获取 Cookie
- 需要把登录态 Cookie 落盘供后续自动化脚本使用
- 需要在 Cookie 失效时自动触发重新登录
核心流程
- 用可视浏览器（Puppeteer）打开目标站点登录页
- 等待用户在浏览器中完成登录（支持手动触发检测）
- 从浏览器抓取目标域的全部 Cookie
- 检查必需 Cookie 是否存在（
requiredCookies） - 用 HTTP 探针请求一个需要鉴权的接口，验证登录态真实可用（
verify） - 校验通过后将 Cookie 保存到指定文件
快速使用
1. 安装依赖
cd .trae/skills/site-cookie-login/scripts
npm install2. 创建站点配置
复制模板并按目标站点修改参数：
cp .trae/skills/site-cookie-login/references/config.template.json .env/<your-site>-login.json3. 执行登录
node .trae/skills/site-cookie-login/scripts/site-login.js --config .env/<your-site>-login.json配置文件说明
配置模板位于 references/config.template.json，所有 <placeholder> 需替换为实际值。
基础字段
| 字段 | 说明 |
|---|---|
name | 站点显示名称，用于日志输出 |
url | 浏览器打开的登录页 URL |
domain | 目标 Cookie 的域名（用于从浏览器筛选 Cookie） |
outputFile | Cookie 输出文件路径（建议使用相对路径，如 .env/.cookie.<site>） |
timeout | 等待登录的超时时间（毫秒），默认 300000（5 分钟） |
Cookie 相关
| 字段 | 说明 |
|---|---|
requiredCookies | 字符串数组，判定登录成功必须存在的 Cookie 名 |
mergeCookieFiles | 可选，额外的 Cookie 文件路径数组，会与浏览器抓取的 Cookie 合并（如 SSO 共享的 Cookie） |
验证探针（verify）
用于通过 HTTP 请求验证 Cookie 是否真正有效：
| 字段 | 说明 |
|---|---|
url | 需要鉴权的 API 端点 |
method | HTTP 方法（GET / POST 等） |
headers | 请求头（Cookie 由脚本自动注入，无需手动填写） |
body | 请求体，留 null 表示无 body |
successStatuses | 视为成功的 HTTP 状态码数组，如 [200] |
rejectBodyIncludes | 响应体中包含任一字符串则判定失败（如 "not login"） |
successBodyIncludes | 响应体中需包含任一字符串才判定成功，留空数组表示不检查 |
验证策略
建议同时启用两层校验以确保可靠性：
- Cookie 存在性检查：通过
requiredCookies确认关键 Cookie 已获取 - HTTP 探针验证：通过
verify发送真实 API 请求确认登录态有效
仅配置 requiredCookies 而不配置 verify 也可以工作，但无法保证 Cookie 未过期。
接入新站点的工作流
- 分析目标站点：在浏览器 DevTools 中登录目标站点，观察哪些 Cookie 是登录态的关键标识
- 找到鉴权接口：在 Network 面板找一个需要登录才能正常响应的 API，用于做登录态探针
- 创建配置文件：基于模板填写站点信息、必需 Cookie、验证接口
- 测试登录流程：运行
site-login.js，确认 Cookie 能正常落盘 - 集成到业务脚本：让业务脚本读取输出的 Cookie 文件，在鉴权失败时可复用此 skill 重新登录
