How it works

工作原理

Navigates to
```

```
via the daemon.
Reads the page HTML.
Parses each story row (HN's stable
```
tr.athing
```
structure) into a typed
```
Story
```
record.
Emits a single JSON document on stdout.

通过守护进程导航至
```
https://news.ycombinator.com
```
。
读取页面HTML内容。
将每个帖子行（HN稳定的
```
tr.athing
```
结构）解析为类型化的
```
Story
```
记录。
在标准输出中输出单个JSON文档。

Why this is the reference skill

为何这是参考技能

hackernews-frontpage

is the smallest interesting browser-skill: no auth, stable HTML, deterministic output, file-fixture-friendly. Every Phase 1 component (SDK, scoped tokens, three-tier lookup, spawn lifecycle) is exercised by

$B skill run hackernews-frontpage

and the bundled

script.test.ts

When the HN HTML rotates and our selectors break, the test fails against the captured fixture before users notice. That's the point.

hackernews-frontpage

是最小型的实用浏览器技能：无需认证、HTML结构稳定、输出确定、支持文件测试用例。

$B skill run hackernews-frontpage

命令及配套的

script.test.ts

会用到第一阶段的所有组件（SDK、作用域令牌、三级查找、生成生命周期）。

当HN的HTML结构更新导致我们的选择器失效时，测试会在用户发现前就针对捕获的测试用例失败。这正是该工具的意义所在。
