FAQ

Frequently asked questions about diffray.

GitHub App Permissions​

What permissions does the diffray GitHub App request?​

The diffray GitHub App requests the following permissions:

Read access​

  • Repository contents - read code for analysis
  • Pull requests - get PR information
  • Repository metadata - basic repository information

Write access​

  • Pull requests - post comments with review results
  • Checks - create and update GitHub Check Runs
  • Issues (via labels) - add/remove status labels

What can diffray NOT do?​

diffray CANNOT:

  • Modify/delete your code
  • Create or delete branches
  • Merge pull requests
  • Change repository settings
  • Delete repositories

Does diffray store my code?​

No. Your code is processed in an ephemeral container during the review process and is completely destroyed after the review completes. diffray does not store or retain your source code.

Can I review the entire project at once?​

Unfortunately, this is not currently possible. diffray only reviews changes in pull requests, not the entire codebase.

What happens if I run out of reviews?​

  • New reviews won't start
  • You'll see an error message in GitHub Check Run
  • Upgrade to a higher package or wait for renewal

Reviews​

Can I cancel a running review?​

Not. Reviews run to completion or fail. If you close the PR, the review will still complete but won't post a comment.

Can I rerun a failed review?​

Yes! Add the diffray-review label to trigger a new review. Failed reviews are automatically refunded.

See: Rerunning Reviews

How do I disable reviews for a repository?​

Remove the repository from Dashboard → Repositories → Click "Remove" button.

Can I review PRs from forks?​

Currently, only PRs from branches in the same repository are supported. Fork PRs are not yet supported.

Why did my review fail with no error?​

Check Dashboard for actual error message. GitHub Check Run may not show all details.
