PR Quiz

What it does

PR Quiz transforms pull request reviews into an interactive learning experience. Give it a public GitHub PR URL or a local repository path, and it analyzes the diff and presents side-by-side code comparisons. You choose which approach is better and explain your reasoning, making code review a two-way learning tool rather than a passive read.

Key features

• Interactive code comparisons — See two versions side by side without knowing which is the PR change, forcing genuine critical thinking
• Flexible input — Works with any public GitHub PR URL or local repository path
• Reasoning prompts — Explain why you picked one approach over the other; the agent reveals the source and discusses trade-offs
• MCP Apps inline UI — Renders directly inside Claude via the io.modelcontextprotocol/ui capability, no browser tab needed
• Highlight.js syntax highlighting — Code comparisons rendered with full language-aware colouring
