Hello! I am Cecil Chang. This is my personal home page, in the spirit of the old web: plain hand-written HTML, no build step, no framework, no tracking — inspired by Fabrice Bellard's home page.
I write about AI agents, context engineering, note-taking, and occasionally economics and philosophy. My code lives on Codeberg. Reach me at mackintosh0516 at 163 dot com.
