"Add from GitHub" missing from + menu in claude.ai chat despite working GitHub Integration

Screenshot

What were you trying to do?

Description:
The "Add from GitHub" option does not appear in the "+" menu of the claude.ai chat
interface, even though the GitHub Integration is fully set up and verified.

Current state (Settings → Connectors → GitHub Integration):

• GitHub account connected: ✅
• Claude GitHub App installed: ✅ (Repository access: All repositories)
• Check repository status: ✅ "Claude Code cloud sessions can work in pridebird/ObdanOne"

Steps to reproduce:

1. Install the Claude GitHub App on GitHub with "All repositories" access.
2. Connect GitHub in claude.ai → Settings → Connectors (all checks green).
3. Open a new chat on claude.ai and click the "+" button in the lower left.
4. "Add from GitHub" is not listed.

Expected: "Add from GitHub" appears in the + menu (as described in the docs)
so repository files can be attached to a chat.
Actual: The option is missing entirely.

Already tried:

• Hard refresh (Ctrl+Shift+R) and opening a new chat
• Disconnecting and reconnecting the GitHub Integration
• [Project knowledge "+" menu: GitHub option appears / does not appear]

Environment:

• Plan: [Free / Pro / Max / Team]
• Surface: claude.ai web
• Browser / OS: [e.g. Chrome 1xx / Windows 11]
• Date: 24 Sep 2026
