When a CI/CD pipeline fails on a pull request, CodeRabbit reads the failure output and posts inline comments with suggested fixes — directly on the lines of code that caused the failure. This works across multiple CI/CD platforms: GitHub Actions, GitLab CI/CD, CircleCI, and Azure DevOps Pipelines.

​
How it works

  1. A pull request is opened or updated and your CI/CD pipelines run.
  2. CodeRabbit waits for pipelines to finish (up to a configurable timeout).
  3. CodeRabbit reads the failure logs and identifies the root cause.
  4. Inline comments with suggested fixes are posted on the relevant lines of code.

Supported platforms

PlatformHow CodeRabbit reads pipeline output
GitHub ActionsVia GitHub Checks — configure timeout under reviews.tools.github-checks
GitLab CI/CDVia GitLab pipeline API, including GitLab Advanced Security SAST/DAST findings
CircleCIVia CircleCI pipeline API (requires integration)
Azure DevOps PipelinesVia Azure DevOps Checks API
For GitHub Actions specifically, the timeout and enable/disable behavior is controlled by the github-checks tool configuration.

​
What failures are analyzed

CI/CD pipeline analysis covers a broad range of failure types:
  • Build failures — Docker, Node.js, Java, Python, Go module errors
  • Test failures — unit, integration, and end-to-end test output
  • Security scan findings — SAST and DAST output from tools like GitLab Advanced Security or custom pipeline steps
  • Infrastructure-as-code validation — Terraform, Kubernetes, Ansible, and CloudFormation errors
  • Linter and code quality output — any linter running as a pipeline step

​
Configuration

For GitHub Actions, control how long CodeRabbit waits for checks to finish using reviews.tools.github-checks.timeout_ms. If your pipelines take longer than 15 minutes, trigger a manual review once they finish:

For all other platforms (GitLab, CircleCI, Azure DevOps), CodeRabbit reads pipeline output automatically with no additional configuration required.

What’s next

GitHub Checks configuration

Configure the timeout and enable/disable behavior for GitHub Actions pipeline analysis.

CircleCI integration

Connect your CircleCI account so CodeRabbit can read pipeline failure logs and post inline fix suggestions.

Pre-Merge Checks

Define custom quality gates that block merges until your standards are met.
