[BUG] Unable to connect claude to private github repository.

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Claude is unable to access a GitHub repo. In Claude settings > connectors GitHub integration is enabled. In the GitHub repo being accessed Settings > Applications > Claude > Repositories shows the repo as accessible. I have tried the add from GitHub function in Claude to send a link to the chat. Now Claude is suggesting filing this bug report to get a manual backend repository index reset for the account.

I am using both Claude and GitHub in browser.
My Claude email is lily.french@mymail.champlain.edu
My github username is LilyFrench10
The private repository is LilyFrench10/sec-480

### What Should Happen?

Claude should be able to access the repository.

### Error Messages/Logs

```shell
Here is a log generated by Claude for this problem
GitHub Connection Attempt Log

Session date: 2026-09-04 Repository in question: LilyFrench10/sec-480 Context: Chat interface (claude.ai), not Claude Code CLI/web

Attempt 1
Target: https://github.com/LilyFrench10/sec-480/tree/main
Method: web_fetch tool (Claude.ai's page-fetch capability)
Result: Failed
Error: ROBOTS_DISALLOWED — "Site disallows automated access. Use the search-result snippet, or find an alternative source."
Attempt 2
Target: https://github.com/LilyFrench10/TechJournal/tree/main
Method: web_fetch tool
Result: Failed
Error: Same as above — ROBOTS_DISALLOWED
Attempt 3
Target: https://github.com/LilyFrench10/sec-480.git
Method: web_fetch tool
Result: Failed
Error: Same as above — ROBOTS_DISALLOWED
Attempt 4
Target: LilyFrench10/sec-480 (indirect, via search)
Method: web_search — general web search for the repo name/owner
Result: No matching results returned for this specific repository
Attempt 5
Target: Same repo link, re-submitted by user
Method: No new fetch attempted — same ROBOTS_DISALLOWED limitation applies, so this was not re-run
Notes for a bug report
These failures are web_fetch limitations (GitHub disallows Claude.ai's page-fetching bot via robots.txt), which is a separate issue from the native GitHub integration ("Add from GitHub" / GitHub App).
User reports the native integration was used: repo was added via "Add from GitHub," and the Claude GitHub App is installed on GitHub with sec-480 explicitly listed under Repository access.
Despite that, the repo has not become accessible/browsable in this chat.
This matches a known, previously-reported pattern (see prior turn) of a backend repository-indexing issue affecting the GitHub App integration, distinct from the web_fetch robots-block above.
Suggested next step

File at github.com/anthropics/claude-code/issues with:

Claude account email
GitHub username
Repo: LilyFrench10/sec-480
Confirmation repo is listed under the app's Repository access
This log as supporting detail
```

### Steps to Reproduce

In Claude go to Settings, Connectors, and connect GitHub. In GitHub go to Settings > Applications and INstall Claude and give it access to the directory. In Claude chat add files, Add from GitHub, then select the repository.
I dont know if this is reproducible, others have done these same steps and have had no issue.

### Claude Model

Sonnet (default)

### Is this a regression?

I don't know

### Last Working Version

_No response_

### Claude Code Version

Claude Sonnet 5

### Platform

Anthropic API

### Operating System

Windows

### Terminal/Shell

Other

### Additional Information

_No response_

No source file, test, or entry point is named. Start by reproducing the Settings > Connectors GitHub flow and the Add from GitHub path, then investigate the backend repository-indexing or reset path described in the log. Done means the private repository becomes selectable and browsable in chat, while keeping the ROBOTS_DISALLOWED web-fetch limitation distinct.
