[BUG] GitHub connector: repo selected via "Add from GitHub" never reaches the conversation

What's Wrong?

GitHub Integration shows as connected at the account level, and I can successfully select a repository through the "Add from GitHub" picker in a Claude web chat. But the selected repo never reaches the conversation. Claude has no GitHub tools available to call, and the repo's contents are never synced into the session — so Claude can't list my repos or read any files from the repo I selected. This happens even for a repo I explicitly picked (e.g. a private repo owner/repo), despite the connector showing a connected checkmark in Settings → Connectors.

What Should Happen?

After I select a repository via "Add from GitHub" in a Claude web chat, that repo's contents should be available to Claude in the conversation, and/or the GitHub connector's tools should be callable — so Claude can actually list my repositories and read files from the repo I selected.

Error Messages/Logs

Steps to Reproduce

1. Confirm GitHub Integration is connected (Settings → Connectors shows a connected checkmark).
2. Open a Claude web chat conversation.
3. Use "Add from GitHub" and select a repository (e.g. a private repo owner/repo).
4. Ask Claude to act on that repo — e.g. "list my repos" or "list the files in this repo."
5. Observe that Claude reports it has no GitHub tools available and cannot see the selected repo; the repo's contents are never synced into the conversation.
