Release Notes

New Audit Rules — Agent Experience (AX)

Three new rules in the Agent Experience category, focused on how well your site serves AI agents and crawlers (242 rules total):

  • ax/llms-txt — detects /llms.txt (and /llms-full.txt) at the domain root and checks its basic Markdown format. An emerging standard that gives AI agents a curated, machine-readable map of your site.
  • ax/markdown-response — checks whether your site serves text/markdown via content negotiation (or exposes a .md variant of the homepage). Agents increasingly prefer clean Markdown over rendered HTML.
  • ax/content-without-js — flags significant main content that only appears in the JS-rendered DOM and is invisible to agents that read raw HTML.

Improvements

  • MCP server — API-key authentication with scope-gated tools for the local stdio server.
  • Faster cloud rendering — render submissions are batched and poll loops coalesced for quicker audits.
  • Faster large-site crawls — URL dispatch and row cleanup are batched to cut overhead on big sites.
  • More accurate domain detection — refreshed the bundled Public Suffix List snapshot.

Fixes

  • Cloud audits that stall past their deadline are now finalized automatically instead of hanging.
  • More efficient handling of error and empty pages during analysis.
