Claude Code C# plugins and skills

Flowy lists 97 plugins for C# 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 C# plugins?
Flowy lists 97 plugins for C#, 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 C# 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 you invoke them yourself.
How does Flowy decide a plugin is a C# 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 C# 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.
