Web Auth Skill

Web 身份认证 Skill

Authenticate to websites by opening a headed browser for the user to complete login manually. The agent monitors for success and persists the authenticated session.

通过启动可视化浏览器让用户手动完成登录，实现网站身份认证。Agent会监控认证是否成功，并保留已认证的会话。

Shell Quoting

Shell 引号规则

Double-quote all URL arguments containing

, or

to prevent shell glob expansion or backgrounding in zsh and bash.

bash

undefined

所有包含

、

或

的URL参数都要使用双引号包裹，以避免在zsh和bash中触发shell通配符扩展或后台执行。

bash

undefined

Correct

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth myapp --url "https://myapp.com/login?redirect=/dashboard"

Wrong - ? triggers shell glob expansion

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth myapp --url https://myapp.com/login?redirect=/dashboard

undefined

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth myapp --url https://myapp.com/login?redirect=/dashboard

Auth Handoff Protocol

认证交接协议

1. Start Session (Optional)

1. 启动会话（可选）

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start <session-name>

Sessions auto-create on first use, so explicit creation is optional.

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start <session-name>

会话会在首次使用时自动创建，因此显式创建是可选的。

2. Start Auth Flow

2. 启动认证流程

For known providers, use

--provider

to auto-configure login URL and success detection:

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --provider <provider>

Available providers: github, google, microsoft, x (alias: twitter), reddit, discord, slack, linkedin, gitlab, atlassian, aws-console (alias: aws), notion.

For custom or self-hosted providers, create a JSON file following the same schema as the built-in providers and pass it via

--providers-file

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --provider my-corp --providers-file ./custom-providers.json

For one-off custom sites, specify the URL and success conditions manually:

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --url <login-url> [--success-url <url>] [--success-selector <selector>] [--timeout <seconds>]

You can combine

--provider

with explicit flags to override specific settings (CLI flags win).

Display auto-detection: If a local display is available, this opens a headed browser window. On remote servers (no display), it automatically falls back to VNC mode - launching Chrome in a virtual framebuffer with a noVNC web viewer.

Use

--vnc

to force VNC mode. Requires:

Xvfb

x11vnc

websockify

novnc

Headed mode (local display):

A browser window has opened at <login-url>. Please complete the login process there.

VNC mode (remote/headless): The command outputs a

vncUrl

- tell the user to open it in their browser to interact with the remote Chrome. If on a private network, they need to forward the port first:

ssh -L <port>:localhost:<port> <server>

对于已知的服务商，使用

--provider

参数自动配置登录URL和成功检测规则：

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --provider <provider>

支持的服务商：github, google, microsoft, x（别名：twitter）, reddit, discord, slack, linkedin, gitlab, atlassian, aws-console（别名：aws）, notion。

对于自定义或自托管的服务商，创建一个与内置服务商 schema 一致的JSON文件，并通过

--providers-file

参数传入：

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --provider my-corp --providers-file ./custom-providers.json

对于一次性的自定义站点，手动指定URL和成功条件：

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth <session-name> --url <login-url> [--success-url <url>] [--success-selector <selector>] [--timeout <seconds>]

你可以将

--provider

与显式参数结合使用，以覆盖特定配置（CLI参数优先级更高）。

显示方式自动检测：如果本地有可用显示器，会启动可视化浏览器窗口。在远程服务器（无显示器）上，会自动回退到VNC模式——在虚拟帧缓冲中启动Chrome，并提供noVNC网页查看器。

使用

--vnc

参数可强制启用VNC模式。依赖项：

Xvfb

x11vnc

websockify

novnc

。

可视化模式（本地显示器）：

已在 <login-url> 打开浏览器窗口，请在此完成登录流程。

VNC模式（远程/无头环境）：命令会输出一个

vncUrl

——告知用户在浏览器中打开该链接以与远程Chrome交互。如果在私有网络中，用户需要先转发端口：

ssh -L <port>:localhost:<port> <server>

3. Parse Result

3. 解析结果

The command returns JSON:

{ "ok": true, "session": "name", "url": "..." }

- Auth successful, session saved

{ "ok": true, "session": "name", "url": "...", "headlessVerification": {...} }

- Auth successful with post-auth verification result

{ "ok": false, "error": "auth_timeout" }

- User did not complete auth in time

{ "ok": false, "error": "auth_error", "message": "..." }

- Something went wrong

```
{ "ok": false, "error": "no_display" }
```
- No display and VNC deps not installed
```
{ "captchaDetected": true }
```
- CAPTCHA was detected during auth
```
{ "vncUrl": "http://..." }
```
- VNC mode: URL for user to authenticate through

Post-Auth Verification: If

verifyUrl

is configured for the provider (or passed via

--verify-url

), the system automatically launches a headless browser after successful auth to confirm the target service is accessible. The optional

headlessVerification

field contains:

json

{
  "ok": true,
  "url": "https://api.github.com/user",
  "currentUrl": "https://api.github.com/user",
  "status": 200,
  "reason": "selector_found",
  "duration": 1523
}

```
ok
```
: Whether the target service is accessible with the authenticated session
```
url
```
: The verification URL that was tested
```
currentUrl
```
: The final URL after any redirects
```
status
```
: HTTP status code (if available)

reason

: One of

selector_found

status_ok

selector_not_found

redirected_to_login

navigation_timeout

, or

browser_error

```
duration
```
: Verification time in milliseconds

If verification fails (

ok: false

), the auth flow still succeeds - the verification is informational only.

命令返回JSON格式的结果：

{ "ok": true, "session": "name", "url": "..." }

- 认证成功，会话已保存

{ "ok": true, "session": "name", "url": "...", "headlessVerification": {...} }

- 认证成功，附带认证后验证结果

```
{ "ok": false, "error": "auth_timeout" }
```
- 用户未在规定时间内完成认证

{ "ok": false, "error": "auth_error", "message": "..." }

- 认证过程中出现错误

```
{ "ok": false, "error": "no_display" }
```
- 无可用显示器且未安装VNC依赖项
```
{ "captchaDetected": true }
```
- 认证过程中检测到CAPTCHA
```
{ "vncUrl": "http://..." }
```
- VNC模式：供用户完成认证的URL

认证后验证：如果服务商配置了

verifyUrl

（或通过

--verify-url

参数传入），系统会在认证成功后自动启动无头浏览器，确认目标服务是否可访问。可选的

headlessVerification

字段包含以下内容：

json

{
  "ok": true,
  "url": "https://api.github.com/user",
  "currentUrl": "https://api.github.com/user",
  "status": 200,
  "reason": "selector_found",
  "duration": 1523
}

```
ok
```
: 使用已认证会话是否可访问目标服务
```
url
```
: 测试使用的验证URL
```
currentUrl
```
: 重定向后的最终URL
```
status
```
: HTTP状态码（若可用）

reason

: 取值为

selector_found

、

status_ok

、

selector_not_found

、

redirected_to_login

、

navigation_timeout

或

browser_error

之一

```
duration
```
: 验证耗时（毫秒）

如果验证失败（

ok: false

），认证流程仍视为成功——验证仅作为参考信息。

4. Handle Failures

4. 处理失败情况

On timeout: Ask the user if they want to retry with a longer timeout.

On error: Check the error message. Common issues:

Browser not found: Dependencies should auto-install on first run. If disabled (
```
WEB_CTL_SKIP_AUTO_INSTALL=1
```
), install manually:
```
npm install && npx playwright install chromium
```
Session locked: Another process is using this session

超时：询问用户是否需要延长超时时间后重试。

错误：查看错误信息。常见问题：

未找到浏览器：首次运行时应自动安装依赖项。如果禁用了自动安装（
```
WEB_CTL_SKIP_AUTO_INSTALL=1
```
），请手动安装：
```
npm install && npx playwright install chromium
```
会话锁定：另一个进程正在使用该会话

5. Verify Auth

5. 验证认证状态

After successful auth, verify the session is still authenticated:

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session verify <session-name> --url <protected-page-url>

For known providers, use

--provider

to use the pre-configured success URL and selectors:

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session verify <session-name> --provider <provider>

The command returns structured JSON:

```
{ "ok": true, "authenticated": true }
```
- Session is valid

{ "ok": false, "authenticated": false, "reason": "..." }

- Session is not authenticated

{ "ok": false, "error": "session_not_found" }

- Session does not exist

{ "ok": false, "error": "session_expired" }

- Session has expired

认证成功后，验证会话是否仍处于已认证状态：

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session verify <session-name> --url <protected-page-url>

对于已知服务商，使用

--provider

参数以使用预配置的成功URL和选择器：

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session verify <session-name> --provider <provider>

命令返回结构化JSON：

```
{ "ok": true, "authenticated": true }
```
- 会话有效

{ "ok": false, "authenticated": false, "reason": "..." }

- 会话未处于已认证状态

{ "ok": false, "error": "session_not_found" }

- 会话不存在

{ "ok": false, "error": "session_expired" }

- 会话已过期

Example: X/Twitter Login (with provider)

示例：X/Twitter登录（使用服务商配置）

bash

undefined

bash

undefined

Start session

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start twitter

Auth using pre-built provider

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth twitter --provider twitter

Verify - check if we see the home timeline

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js run twitter goto "https://x.com/home" node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js run twitter snapshot

undefined

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js run twitter goto "https://x.com/home" node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js run twitter snapshot

undefined

Example: GitHub Login (with provider)

示例：GitHub登录（使用服务商配置）

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start github
node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth github --provider github

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start github
node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth github --provider github

Example: Custom Site (manual config)

示例：自定义站点（手动配置）

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start myapp
node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth myapp --url "https://myapp.com/login" --success-url "https://myapp.com/dashboard"

bash

node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session start myapp
node /Users/avifen/.agentsys/plugins/web-ctl/scripts/web-ctl.js session auth myapp --url "https://myapp.com/login" --success-url "https://myapp.com/dashboard"
