## How to resolve

### GitHub not connected

1. Follow the `auth_url` in the response to connect your GitHub account to Warp.
2. Complete the OAuth authorization flow.
3. Retry the task.

### Repository inaccessible

1. Follow the `auth_url` to install or reconfigure the Warp GitHub App.
2. Ensure the app has access to all repositories listed in `inaccessible_repos`.
3. Retry the task.

If you are using a **team API key** (service account), ensure the Warp GitHub App is installed on the organization that owns the repositories.

### Account matching failed

1. Ensure your Slack or Linear account is associated with the same email as your Warp account.
2. If using Slack, verify the Warp Slack integration is installed in your workspace.
3. Contact your team admin if the issue persists.
