FAQ

What are the best Claude Code Code Generation plugins?
Flowy lists 19 plugins for Code Generation, 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 Code Generation 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 Code Generation 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 Code Generation 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.
