SpockFetch: the page reader of Spock (https://spock.chat), an AI assistant.

What it does
  When a user asks Spock about something on the web, Spock reads the pages that question
  needs, on that user's behalf, in real time. It fetches one page per need. It does not
  crawl, build an index, or use pages to train models.

How to recognise it
  User-Agent: SpockFetch/1.0 (+https://spock.chat)
  Every request is signed with Web Bot Auth (RFC 9421); the key directory is at
  https://agent.spock.chat/.well-known/http-message-signatures-directory
  Pages that need JavaScript are opened in a browser session in the requesting user's
  own sandbox.

What it respects
  robots.txt rules addressed to SpockFetch.
  Content-Signal: ai-input=no (the site's pages are not read as AI input).
  A block or challenge from the site: Spock stops and tells the user. It does not retry
  through other networks or disguise itself.
