No-Numb

Quizzes you on the code Claude Code just wrote

github.com

I noticed I was shipping code I could not explain. No-Numb waits until the agent has edited a file, then makes it quiz me on what it just did. Get one wrong and it shows the answer and why, then asks again. The session does not move on until I pass. The friction is the point.

  • 32 stars and 100+ unique cloners on GitHub
  • Stop hook intercepts only turns that edited or wrote a file, so pure conversation is never quizzed
  • Questions arrive one at a time as multiple choice through Claude Code's native AskUserQuestion UI
  • A wrong answer shows the right one and explains why, then the quiz retakes lightly reworded so the key cannot be memorised
  • Two-key config surface: enabled as the forcing function, and depth for questions you can answer from the decisions versus ones that make you open the file
  • Shipped as an installable plugin with its own marketplace manifest

Bash, jq, Claude Code Hooks, Plugin Marketplace, Markdown Skills, JSON
