David Dias has been working on “Front-End Checklist” stuff for a decade, and it looks like this latest version of it a little over a year. There is loads of good general advice in it that can be easy to forget:
- Did you do a print stylesheet?
- Did you accidentally lazy load (or not preload) the hero image?
- Are you respecting reduced motion preferences?
Now it’s all AI’d up, which makes sense, having a skill and MCP so your agent can check your sites against all this advice.
