Loop: is the website ready for AI agents

loop.ru·checked November 11, 2026
68.5out of 100
Has issues

Agents read the site but miss some important things.

Paste the task into Claude Code, Cursor or another agent with access to the site’s code.

  • Agent access: 100
  • Discoverability: 81
  • Content for models: 42
  • AI bot rules: 64
  • API and protocols: 41

Fix these first

First, what gets in agents’ way the most.

  1. 01

    The site serves Markdown when an agent asks

    Failed

    When the homepage is requested with “Accept: text/markdown”, return Markdown with “Content-Type: text/markdown” and “Vary: Accept”. Keep serving HTML for ordinary requests.

    An agent can ask for a page in Markdown instead of HTML and spend far less of its budget on markup.
