Show HN: Coreview – PR Changes Walkthroughs

I have been building coreview - a toy tool that takes a diff and explains it, with the goal to provide more context to the reviewer.

npm i -g coreview

coreview -p https://github.com/anthropics/claude-code/pull/20662

It works with Claude Code for now, but more providers can be implemented. Would love to hear feedback.
