How Airglow identifies it
- DeclaredIt names itself in the User-Agent:
Claude-User.
Every visit in Airglow says which of these applied, so you can decide how much to trust it.
Seeing it on your site
It usually reads pages without running JavaScript, so Airglow counts every visit through a server connection (Cloudflare). When it does run JavaScript, the script sees and replays it too.
Allowing or blocking Claude-User
Claude-User reads the Claude-User group in your robots.txt. To keep it out of the whole site:
User-agent: Claude-User Disallow: /
Anthropic runs a separate bot for each purpose, so blocking Claude-User doesn't block its other agents listed below.
Airglow shows, for every agent that visits, whether your robots.txt lets it in, and helps you write rules by purpose (training, search, acting for a person).
