[BUG] Claude Code on the web — org repos not visible despite GitHub App installed with 'all repositories'

Summary

The Claude Code on the web repo picker only surfaces my personal GitHub account's repo (thriveflorida/lifebit-crm) and refuses to display repos from my org (Thrive-Mental-Health-LLC) — despite the Claude GitHub App being properly installed on the org with "All repositories" selected.

This blocks the @Claude-tag-in-Slack workflow entirely for org-owned repos, since that integration relies on the same picker.

Environment

• Claude account: nate@gothrivemh.com
• Plan: Max
• GitHub user: thriveflorida (Owner of Thrive-Mental-Health-LLC)
• Org: Thrive-Mental-Health-LLC (GitHub Enterprise Cloud, NOT EMU)
• Affected repos: Thrive-Mental-Health-LLC/ThriveEHR, Thrive-Mental-Health-LLC/ThriveSEO
• Visible repo (only one): thriveflorida/lifebit-crm

Verification done

I've verified every documented requirement from the Claude GitHub integration setup. Everything is correct on my side:

| Layer | State | How verified |
|---|---|---|
| Claude GitHub App on org | ✅ Installed, All repositories, suspended_at: null, updated 2026-05-10T11:37 | gh api orgs/Thrive-Mental-Health-LLC/installations |
| Claude GitHub App on personal user | ✅ Installed | Same API |
| OAuth grant for personal user | ✅ Says "Claude has been installed on 2 accounts you have access to: Thrive-Mental-Health-LLC and thriveflorida" | https://github.com/settings/connections/applications/Iv23liqTIFEtdIu6Vn1r |
| Authorized GitHub Apps tab | ✅ Claude listed, no SSO warning banner | https://github.com/settings/apps/authorizations |
| SAML SSO (org has it enabled) | ✅ No "needs authorization" warnings on either GitHub Apps page or SSO and organizations page | Verified via UI |
| ip_allow_list_enabled_setting | ✅ null (not enabled) — apps not blocked | gh api orgs/Thrive-Mental-Health-LLC |
| ip_allow_list_for_installed_apps_enabled_setting | ✅ null | Same |
| Repos accessible via GitHub App API | ✅ Both ThriveEHR + ThriveSEO returned | gh api orgs/Thrive-Mental-Health-LLC/installations then enumerate repositories |
| gh CLI from my laptop can access both repos | ✅ Works | gh repo list Thrive-Mental-Health-LLC |

Steps to reproduce

1. Sign in to claude.ai/code with nate@gothrivemh.com
2. Repo picker at the bottom shows: Default | </> lifebit-crm | main
3. Click lifebit-crm to open the picker
4. Picker shows search input + only one option: thriveflorida/lifebit-crm
5. Search for "ThriveEHR" or "Thrive-Mental-Health-LLC" → result: "No repos match. Repo missing? Install the Claude GitHub app in a private repository to access it here."
6. Click "Install the Claude GitHub app" → opens GitHub App install page → both thriveflorida and Thrive-Mental-Health-LLC show "Configure" (already installed)
7. Confirm via Configure button on Thrive-Mental-Health-LLC: "All repositories" radio is selected; click Save → redirects to claude.ai/settings/general (suggesting the webhook fired)
8. Hard refresh claude.ai/code: ThriveEHR still NOT in picker

Things that did NOT fix it

• ✗ Sign out + sign in to claude.ai
• ✗ Hard refresh (Cmd+Shift+R)
• ✗ Click Save on the org GitHub App config page (re-triggers webhook)
• ✗ Switch repo selection from "All" → "Selected" → "All" again

Effect on Slack-tagged @Claude

The Slack integration relies on this picker. When I @Claude in a #platform-updates channel asking about ThriveEHR code, the response is:

"No repositories found. Please connect your GitHub account at claude.ai and try again."

Which is misleading — the GitHub account IS connected; the repos just aren't surfacing.

Related issues (probably duplicates)

• #34523 — "No repositories found" on Claude Code mobile after GitHub App installation
• #27155 — GitHub repos not visible in Claude web despite app installed
• #54330 — Repos not appearing after reconnecting account (workaround: clone locally)
• #18467 — Personal repos not visible, only orgs work (opposite of this case)
• #12839 — Claude Code fails to sync after GitHub App reinstall
• #57396 — Personal repo not appearing despite reinstall

Workaround in use

I'm running my work via the Claude Code CLI instead, where the same repo IS accessible because file operations work directly. The web picker / Slack-tag workflow is the only blocked surface.

Ask

Whatever backend indexing job populates the per-user repo list on claude.ai/code — please check why my user (nate@gothrivemh.com, GitHub thriveflorida) isn't getting the org's installation merged into it. The org install has "All repositories"; the user is an Owner; SSO is fine; nothing on my side is blocking.
