What probably matters to youSection of the release
What
The self-hosted runner tools now check up front that you are on Anthropic's own API and signed in with claude login. An API key is not accepted. Failures carry the HTTP status, and 401 or 403 responses append a hint pointing at claude login and ANTHROPIC_BASE_URL.
Details
The API base is ANTHROPIC_BASE_URL with trailing slashes stripped, falling back to the built-in Anthropic API URL.
These tools are only reachable from the setup and doctor wizards.
Evidence
Self-hosted runner management is only available on the first-party Anthropic API provider.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
