DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
When OAuth token operations fail, the specific error type is now captured and classified (expired token, invalid token, no organization, no account associated).
Evidence
New OAuth error classification (search for "Refresh token expired" or "No organization associated with this token")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
