Claude for Product Builders: 32 Claude skills for taking one idea from a question to a prototype real users can try, and on to a build, change or stop decision, in eight stages: frame it with a problem frame, an idea one-pager and a prototype test card with a dated pass line; spec it with a prototype brief, a screen-by-screen user flow and a prototype spec; build a clickable prototype in Claude Design; make one flow really work in Claude Code; check it is safe to show with a secrets and keys check, a personal data check, an access and sharing check and a pre-share sign-off; test it with five real target users; hand it to engineering with everything faked written down; then get a decision from a named person. For product managers and product designers who want to build a prototype themselves, and founders shaping a first product. Claude builds the prototype, real users test it and engineers own what ships.

Want this mark on your plugin in our catalog?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works
You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.
Data comes from public marketplace files in GitHub repositories of their authors. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
