It's absurd how fast you can improve a web app's agent readiness, performance, SEO/GEO, security, accessibility, and more by pointing Claude Code or Codex at this Website Spec site (specification.website) with a prompt like "Check the current implementation against this set of agent readiness specifications and report on what the application does well, where it needs improvement, and what you recommend we fix immediately: specification.website/spec/agent-rea…" Run that prompt while in your codebase. You don't need to fix everything all at once, but you're guaranteed to make huge improvements in all of those areas just by using that specification site to incrementally improve with an AI coding agent. If you want to see an example of what's generated before trying this yourself, take a look at this example output I had from running it on Plushcap's live website and codebase: plushcap.com/blog/improving…
