Claude Code Jest plugins and skills

Flowy lists 32 plugins for Jest work in Claude Code. Each one bundles skills a Claude Code agent can load while you work. Every listing shows what is inside before you install, who built it, and whether it is Auto-invoked, meaning a FLOW.md router fires the right skill as you prompt instead of leaving them dormant.

FAQ

What are the best Claude Code Jest plugins?
Flowy lists 32 plugins for Jest, ranked by fit and signal rather than raw install count. Open any listing to read every skill in full before you install it.
Do these Jest skills run automatically?
The Auto-invoked ones do. They ship a FLOW.md router and a hook, so Claude Code loads the matching skill as you prompt. Indexed listings install normally, and their skills fire only when Claude picks them from their descriptions.
How does Flowy decide a plugin is a Jest plugin?
The tag is derived from the plugin's own content, its skill names, descriptions, README and file types, not from a tag someone typed. A plugin appears here only when its real content matches.
Are these Jest plugins free?
Yes. Flowy is free and open source with nothing gated. You can read every skill before installing, and each listing links to its upstream repository and its creator.
