What

When Claude Code reads an authentication token from a file at a known location, a failed read now reports a reason instead of just "no token": the file was empty, missing, unreadable due to permissions, or failed for another cause.

Details
  • Callers can distinguish "no token configured" from "token exists but cannot be read", which previously looked identical.
Evidence

Read ${s} from well-known file ${e}

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
