What's Wrong?

Summary
The GitHub integration connector in Claude settings completes OAuth
authorization but never triggers the GitHub App installation
step, so repository write access (Contents: Read & write) is never
granted. This blocks Claude Code (web/remote sessions) from pushing
commits to a user's repos even though the session reports those repos
as "in scope."
Environment
Product: Claude Code on the web / remote execution session
Affected connector: Settings → Connectors → "GitHub Integration"
GitHub account: personal account (not an org)
Session had two repos pre-scoped as sources: both freshly created,
fully empty (no commits/branches yet)
Actual behavior
Reconnecting only re-adds "Claude" to the GitHub Authorized OAuth
Apps list. It never surfaces GitHub's App-installation /
repository-picker screen.
The GitHub App itself remains uninstalled on the account (confirmed
via the app's own authorization page: "Claude has not been installed
on any accounts you have access to").
As a result, all repository write operations fail, while read
operations succeed:

Impact
Any Claude Code web/remote session whose GitHub App installation is in
this stuck state can browse/read repos (and the session setup even
lists them as valid "sources") but can never actually commit or push,
with no actionable in-product path to fix it — the only connector
control available is Disconnect, which just repeats the same broken
OAuth-only reconnect.
Suggested fix
Make the Connectors → GitHub Integration "connect/reconnect" flow
explicitly route through GitHub's App installation URL (the
repository-picker step), not just the OAuth authorize consent
screen, so users can't end up authorized-but-not-installed.
Alternatively, detect this specific state (OAuth authorized, App not
installed) and surface an explicit in-product error/CTA instead of
showing the connector as fully "connected" with a green check.

What Should Happen?

Expected behavior
Reconnecting the GitHub Integration connector should walk the user
through the full GitHub App flow: OAuth authorize and app
install/repository selection (the picker where you choose "All
repositories" or specific repos, and grant Contents: Read & write).
After that, Claude Code should be able to push commits/branches to the
selected repos.

Error Messages/Logs

`mcp__github__create_or_update_file` → `403 Resource not accessible by integration` on
`PUT /repos/<owner>/<repo>/contents/<path>`
`mcp__github__push_files` → same 403, `failed to initialize repository: failed to create initial file`
Direct `git push` through the session's local git credential proxy
(`http://127.0.0.1:<port>/git/...`) → `403` as well
By contrast, `git clone` of the same (empty) repo, and
`mcp__github__list_branches` / `get_file_contents`, all succeed —
confirming this is a write-permission gap, not a connectivity or
proxy issue (the session's agent-proxy status endpoint showed no
recorded egress-policy denials either).

Steps to Reproduce

Steps to reproduce
Start a Claude Code on the web session with a GitHub repo (or repos)
attached as sources.
Ask Claude to push a commit to one of the repos on a feature branch.
Observe the push fail.
In Claude Settings → Connectors, open "GitHub Integration" — it
shows as connected (green checkmark), with only a Disconnect
button, no repository-access management link.
Click Disconnect, then Add → reconnect GitHub.
Complete the GitHub OAuth consent screen.
Check github.com/settings/connections/applications (Authorized
OAuth Apps) — "Claude" is listed there, authorized.
Check github.com/settings/installations (Installed GitHub Apps) —
"Claude" does not appear (or shows "never used" / "not
installed on any accounts you have access to" on the app's own
authorization page).
