Connect Codex to Google PageSpeed

Give an AI agent your Pagespeed node as a tool and it can measure a page's real performance itself instead of guessing at it. It can analyze a URL on mobile or desktop, pull the Performance, SEO, Accessibility, and Best Practices scores, read Core Web Vitals and lab metrics, and list the exact opportunities to fix, calling each one as a tool while it works. Wire it into a hosted coding agent in NoClick and it can audit a page, act on what it finds, and re-check the score afterward.

What you can build

Every morning, run a full analysis on your homepage and post the Performance score and Core Web Vitals to Slack so regressions get caught early.
When a deploy webhook fires, analyze the key landing pages on both mobile and desktop and flag any page whose Performance score drops below your threshold.
Pull the list of opportunities for a slow page, hand them to an AI step, and open a ticket with the ranked fixes.
On a weekly schedule, collect All Category Scores for a list of URLs and append them to a Google Sheet to track SEO and Accessibility over time.
Compare lab metrics against Origin Core Web Vitals for a URL to see whether real users experience the same speed your tests report.
Capture a screenshot and the Best Practices score for each new marketing page before launch and attach both to the review.
