Feed Patterns

Amethyst's "feed" abstraction is: a FeedFilter that decides which notes belong in a list, plus a FeedViewModel that exposes the current state reactively to the UI. Every scrollable list — home, profile, hashtag, bookmarks, notifications, DMs — is a variant of this.

When to Use This Skill

• Adding a new screen that shows a list of notes.
• Modifying an existing feed's filtering / ordering / inclusion rules.
• Investigating why a feed doesn't update after a mute/follow/bookmark change.
• Deciding whether to extend a ViewModel or write a new filter.
• Understanding the Android ⇄ Desktop sharing boundary for feeds.
