Scrape the Hacker News front page (titles, points, comment counts).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hacker News front-page scraper
Scrapes the Hacker News (`news.ycombinator.com`) front page and returns the
top 30 stories as JSON. Each story has its rank, title, link URL, point count,
and comment count.
## Usage
```
$ $B skill run hackernews-frontpage
{
"stories": [
{ "rank": 1, "title": "...", "url": "...", "points": 412, "comments": 87 },
...
],
"count": 30
}
```
## How it works
1. Navigates to `https://news.ycombinator.com` via the daemon.
2. Reads the page HTML.
3. Parses each story row (HN's stable `tr.athing` structure) into a typed
`Story` record.
4. Emits a single JSON document on stdout.
## Why this is the reference skill
`hackernews-frontpage` is the smallest interesting browser-skill: no auth,
stable HTML, deterministic output, file-fixture-friendly. Every Phase 1
component (SDK, scoped tokens, three-tier lookup, spawn lifecycle) is
exercised by `$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.Read the whole file at its exact version.
How to install
mdr add garrytan/gstack/hackernews-frontpage@sha256:1a4e91d00ffdbdd3The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
