What are the best Claude Code Slack plugins?

Flowy lists 5 plugins for Slack, 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 Slack 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 Slack 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 Slack 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.
