widget-composition
Skill0 starsChanged 3 months agoNo licenceView on GitHub
Enforces Flutter widget composition — extract named const Widget classes never `Widget _buildX()` methods, lean build() (no I/O/formatting/domain math, precompute in the ViewModel), dumb Views that watch one Notifier and route intents via ref.read, StatelessWidget by default with every controller disposed, lazy `.builder` lists, cheapest-widget choices (SizedBox/ColoredBox/Align over Container), a strict key policy (ValueKey for reorderable lists, never GlobalKey), gesture→visible-focusable-fallback wiring, plus structural layout — full-bleed background vs SafeArea content, computed cell sizing, the GridView cross/main-axis spacing trap, EdgeInsetsDirectional, and resizeToAvoidBottomInset/IME handling. Use when building or refactoring any screen or widget, splitting a large build() into components, writing GridView/ListView/LayoutBuilder/SafeArea/Scaffold, wiring onTap/onLongPress/Draggable, choosing a key or data class, or reviewing widget code in a diff.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
7 rules. About 0 are common, 2 are distinctive, and 5 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈2
Distinctive · estimate
This author's own choices. Worth a look.
5
Very specific
Tied to their project's names, files or tools. Probably skip.
No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
