/install-github-app now recognizes SAML SSO enforcement and explains how to re-authorize
/install-github-app, which installs the Claude GitHub App for a repository, now recognizes when a repository access check fails because of SAML single sign-on (SSO) enforcement. Instead of showing a generic failure, it shows "Single sign-on authorization needed" with instructions to either re-authorize the GitHub CLI login and authorize the organization for SSO, or configure SSO on a personal access token.
Organizations that enforce SAML SSO on GitHub previously got an unhelpful generic error during setup. Now the command tells the user exactly what's blocking access and how to fix it.

Anthropic's documentation has since written up /install-github-app, on Error reference.
Fixed /install-github-app reporting a SAML single sign-on block as "admin permissions required"
