What’s changing:
The CircleCI GitHub App now subscribes to pull_request_review_comment events from GitHub.
What to expect: If you have the CircleCI GitHub App installed, you received an email from GitHub notifying you of this change. When you click “Review permission request” in the email, you’ll see the notice below.

Action required – You’ll need to accept this permission request before CircleCI can start processing these events for your organization. Click “Accept new permissions” in the email or visit your GitHub App settings to approve the change.
The notice shows “unchanged permissions” because the GitHub permissions needed for this event were already granted to the CircleCI App—we’re simply subscribing to an additional event type using those existing permissions.
Why we’re making this change: This event subscription enables two new capabilities:
- Chunk interactions: Trigger pipelines and invoke AI agents directly from PR comments (e.g.,
@chunk-ai fix flaky tests) - Future trigger options: Configure pipelines to run based on specific PR comments
