A CKEditor 5 callout-box plugin generated with Claude Code - an early experiment in letting an AI coding agent build a complete editor plugin, deployed live on Netlify.
Released: Tue Jun 24 2025
What's inside
A callout/admonition plugin for CKEditor 5 - and an early data point in a question I keep returning to: how well can an AI coding agent build a real editor plugin end to end? This one was generated with Claude Code and shipped to Netlify as-is.
Why it exists
It predates the official CKEditor support for AI coding agents, which made experiments like this dramatically more reliable - the before-picture, if you will.
