What's Wrong?

Using Claude Code (remote/cloud session) with the GitHub connector attached to a personal repo I own. Read access works fine. All write operations fail with 403 Resource not accessible by integration:

git push over the session's git proxy → 403 on git-receive-pack
GitHub API POST /repos/{owner}/{repo}/git/refs (create branch) → 403
GitHub API PUT /repos/{owner}/{repo}/contents/{path} (create/update file) → 403

Fully uninstalled the GitHub App/OAuth grant on GitHub's side and reconnected the connector from claude.ai settings. After reconnect, read access returned but write access still failed with the identical error — no fresh consent screen for repo write scope was shown during reconnect. claude.ai/admin-settings (for managing GitHub App permissions) redirects to "available on Team/Enterprise plans only," suggesting write access may be plan-gated with no path to grant it on a personal plan, but this isn't stated anywhere in the connector UI itself.

Expected: either write access should be grantable during the connect/reconnect flow, or the product should clearly state write access requires Team/Enterprise before a user spends time debugging permissions.

What Should Happen?

When I reconnect Github,it should allow me to grant write access.

Error Messages/Logs

fatal: unable to access 'https://github.com/XYZ/': The requested URL returned error: 403

Steps to Reproduce

1. Grant read access to Github - Claude connector
2. Use Claude on the web, ask it to create a PR, it'll fail
3. You reconnect the Github - Claude connector, nothing changed. No way to grant write access.
