About

rubber-duck is a plugin bundle for AI coding tools published by mo-inkhan. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-20.

In its own words, on Claude Code: claude-plugins-community:

rubber-duck is a Socratic thinking partner for Claude Code. Inspired by the classic rubber duck debugging technique—but with a duck that actually talks back—it helps you think through problems instead of just handing you answers. While most AI tools focus on writing code for you, rubber-duck is designed to help you learn it. Rather than giving you the fix, it asks the right question at the right time—guiding you step by step, at your own pace. Use Claude when you need to ship fast. Use rubber-duck when you want to understand what you’re building. The best developers use both.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.

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 the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
