When your GitHub checks fail, Codegen automatically wakes up to analyze the failures and fix your PR. This intelligent system monitors CI status and proactively resolves issues without manual intervention.

Codegen will try to fix broken checks 3x before “tapping out”

​
How Wake Up Works

Codegen continuously monitors your pull requests and automatically responds to check failures:

  • Automatic Detection: Monitors GitHub check runs and CI status in real-time
  • Intelligent Analysis: Analyzes build logs, test failures, and error messages to understand root causes
  • Targeted Fixes: Generates specific code changes to resolve the identified issues
  • Persistent Retry: Will attempt to fix issues up to 3 times per PR

​
What Triggers Wake Up

Wake up activates when:

  • CI Checks Fail: Any GitHub check run reports a failure status
  • Build Errors: Compilation, linting, or build process failures
  • Test Failures: Unit tests, integration tests, or automated test suites fail
  • Code Quality Issues: Static analysis tools report violations or warnings

​
The Auto-Fix Process

When Codegen wakes up to fix a failing PR, it follows this process:

  1. Detect Failure: Monitor check status and identify when builds break
  2. Analyze Logs: Grep through CI logs to understand specific failure points
  3. Generate Solution: Create targeted code changes to resolve identified issues
  4. Apply Fix: Automatically commit fixes to the same PR branch
  5. Re-validate: Monitor the new check run to ensure the fix was successful

​
Retry Logic

Codegen implements intelligent retry behavior:

  • Up to 3 attempts per PR to resolve failing checks
  • Progressive analysis - each retry incorporates learnings from previous attempts
  • Failure escalation - if 3 attempts fail, the issue is flagged for human review

​
GitHub Integration

The wake-up system integrates deeply with GitHub:

  • Check Run Annotations: Creates detailed feedback with line-specific suggestions
  • PR Comments: Adds contextual suggestions and explanations
  • Auto-Fix Actions: Provides one-click fix buttons in the GitHub UI
  • Status Updates: Real-time updates on fix progress and results

Wake up only activates for repositories where Codegen has write access and the feature is enabled. It respects your repository permissions and team workflows.

Benefits

  • Reduced Context Switching: No need to manually investigate and fix CI failures
  • Faster Iteration: PRs get fixed automatically, keeping development velocity high
  • Learning from Failures: Each fix improves Codegen’s understanding of your codebase
  • 24/7 Monitoring: Works around the clock to keep your PRs in good shape
