## What it does

The skill separates read and write flows into two distinct transports. Browsing top stories, filtering by domain, and fetching discussion trees go directly through the Algolia Search API and Firebase. No browser runs during reads. Note that raw text fields like `comment_text` return HTML fragments.

Write actions run through a browser page session. Upvoting stories or posting replies requires an active login state. Deleting comments works as well, but only within the two-hour window enforced by Hacker News.

# Hacker News

## Overview
Tech news aggregator by Y Combinator. Reads via Algolia Search API and Firebase API (node-direct). Writes via browser page context.

## Workflows

### Browse and read a story
1. `getTopStories` → pick story → note `objectID`
2. `getStoryDetail(id)` → title, url, points, author, nested comment tree

### Upvote a story
1. `getTopStories` → pick story → `objectID`
2. `upvoteStory(id=objectID)` → `{ok, id}` (requires login)
3. `unvoteStory(id=${prev.upvoteStory.id})` → `{ok, id}` — reverses the upvote (only valid while upvoted)

### Comment on a story
1. `getStoryDetail(id)` → `item.id`
2. `addComment(parent=item.id, text)` → `{ok, parent, id}` — `id` is the new comment's id (requires login)
3. `deleteComment(id=${prev.addComment.id})` → `{ok, id}` — must be within HN's ~2-hour delete window

### Reply to a comment
1. `getStoryDetail(id)` → `children[]` → pick comment → `comment.id`
2. `addComment(parent=comment.id, text)` → `{ok, parent, id}` — posts reply (requires login)

### Explore a user
1. `getUserProfile(id)` → karma, created, about
2. `getUserSubmissions(id)` → stories they posted
3. `getUserComments(id)` → their comment history

### Find stories from a domain
1. `getStoriesByDomain(query)` → all stories linking to that domain

### Read latest activity
1. `getNewComments` → newest comments across all stories
