# Is your site ready for AI agents? Lighthouse now has an answer

**[iO tech\_hub](https://daily.dev/sources/iotechhub)** · 5 min read · 46 upvotes · 7 comments

## Summary

Google Lighthouse has added a new 'Agentic Browsing' category that audits how well websites work for user-facing AI agents. Unlike other Lighthouse categories, it provides pass/fail diagnostics rather than a 0-100 score. The audits cover four areas: presence of an llms.txt file (a robots.txt equivalent for AI agents), WebMCP integration (a Chrome Origin Trial API for explicitly exposing site actions to agents), accessibility tree quality (semantic HTML and ARIA labels that agents rely on for navigation), and Cumulative Layout Shift (CLS) stability to prevent agents from clicking wrong elements. The category is designed to be integrated into CI/CD pipelines as a quality gate on every deploy, treating agentic readiness as a first-class metric alongside performance and accessibility.

> Very smart choice. I'm pretty sure all web developers will be very happy that now they have to adapt their website to agents as well.

> Great addition! Checking for `llms.txt` and a stable accessibility tree is exactly what developers need to start thinking about as AI agents become more common. Looking forward to testing this in CI/CD

> A pass/fail category instead of a 0 to 100 score is the right call here, because agent-readiness is closer to a contract than a quality gradient: the llms.txt and WebMCP hooks either exist or they do not. The CLS audit being in scope is the detail I did not expect, and it is the smart one, since a layout shift a human ignores can make an agent click the wrong element. I suspect the accessibility-tree checks will end up doing more for real agents than most of the explicit agent APIs.
