What is Crush?
Crush is a coding agent for the terminal, made by Charm. Its fetch tool requests pages from the developer's own machine and identifies itself only as crush/1.0, without the AI model it runs on.

- Class
- Coding agent fetching docs
- Verification
- User agent onlyCrush runs on its user's own machine. DevTune identifies it by user agent, and requests carrying that user agent come from that person's own network, so they usually can't be authenticated.
On your site
When it requests a page itself, often documentation a developer's coding task needs, the request carries its user agent. AI Traffic counts those page requests as answer fetches, and counts coding-agent answer fetches on their own too.
AI Traffic setup
Connect a crawler sensor (Cloudflare pull, edge middleware or a Vercel log drain) to see which pages Crush requests on your site.
