What's Wrong?

Subject:

Issue: Creating a scheduled cloud routine (via claude.ai/code routines, RemoteTrigger API) that references a GitHub repository fails with:

What Should Happen?

Ask: How do we properly install/authorize the Claude GitHub App for this account so scheduled routines can reference this repo? The self-serve magic link appears broken or is not surfacing the expected flow.

Error Messages/Logs

HTTP 401
"Connect your GitHub account before saving a routine that uses a GitHub repository."

Steps to Reproduce

Steps already taken:

1. Followed the in-product guidance link https://claude.ai/code/onboarding?magic=github-app-setup — this does not trigger any GitHub OAuth or App-install flow. It just opens/resumes the current Claude Code chat session in the browser.
2. Checked github.com/settings/installations directly on the GitHub account in question — no app named "Claude" appears under Installed GitHub Apps (only ChatGPT Codex Connector, lovable.dev, Railway App, and Vercel are listed).
3. Searched GitHub Marketplace for "Claude Code" — only found unrelated GitHub Actions listings (Claude Code Action Official, Claude Code Base Action, etc.), not an installable GitHub App matching what the routine flow needs.
4. Retried the routine creation multiple times after each step above — same 401 every time.
