What is the CI/CD Agent?

CI failures shouldn’t break your momentum. TierZero CI/CD Agent diagnoses build failures, detects flaky tests, and tracks CI health metrics, so your team ships instead of debugging pipelines.

​
Key Capabilities

​
CI Failure Diagnosis

When a build fails, TierZero reads the logs, identifies the root cause, and tells you what broke and why. No more scrolling through 500 lines of build output to find the one error that matters.
  • Intelligent log parsing: Parses build logs across CI providers to pinpoint the exact failure, filtering out noise from thousands of output lines.
  • Error attribution: Correlates failures with recent code changes, environment diffs, and dependency updates to identify the root cause.
  • Fix suggestions: Recommends specific fixes based on the failure pattern, from missing env vars to version conflicts.

​
Flaky Test Detection

Flaky tests are never “just flaky.” TierZero collects evidence across hundreds of historical failures to identify the pattern.
  • Statistical detection: Analyzes pass/fail patterns across runs to identify flaky tests with high confidence, not just “did it fail once.”
  • Quarantine: Isolate flaky tests and page issue owner so that the build train keeps chugging.
  • Production-informed test validation: Prioritizes tests by production failure correlation to focus CI resources on tests that catch real production issues.

​
CI Health Tracking

Track the metrics that matter: PR Merge to Live time, build success rates, and pipeline throughput.
  • PR Merge to Live tracking: Create new baselines or integrate with your existing dashboards. Measure well so you can improve.
  • Build success trends: Tracks success rates over time so regressions don’t become the norm.

​
Automated Fix PRs

When CI Agent diagnoses a failure, it can propose fix PRs automatically.
  • Notifies the PR owner with the diagnosis
  • Opens a fix PR ready for review and merge
  • Approval required before merge (human-in-the-loop)

​
Use Cases

​
Reduce CI Debugging Time

  • Challenge: Engineers spend 20+ hours per week debugging pipeline failures.
  • How it works: CI/CD Agent parses build logs, correlates with code changes, and surfaces the root cause with a fix suggestion.
  • Outcome: 20+ hours saved per week across the team.

​
Faster PR Merge to Live

  • Challenge: Flaky tests and intermittent failures slow down the merge pipeline.
  • How it works: Flaky tests get detected and quarantined. CI health metrics surface bottlenecks.
  • Outcome: 27% faster PR Merge to Live on average.

​
Focus CI Resources on What Matters

  • Challenge: CI runs thousands of tests, but not all are equally valuable.
  • How it works: Production-informed test validation prioritizes tests that correlate with real production failures.
  • Outcome: CI resources focused on high-value tests, fewer false positives.

​
How to Set Up

  1. Navigate to CI/CD in the sidebar
  2. Connect your code integrations (GitHub, GitLab, or Bitbucket)
  3. Connect your CI/CD platform (Buildkite or GitHub Actions)
  4. Configure which pipelines and repositories to monitor
  5. Set up notification channels for failure diagnoses

​
Best Practices

1. Start with Highest-Traffic Pipelines
  • Focus on the pipelines that affect the most engineers first
  • Maximize impact and build confidence in the agent’s diagnoses
2. Review Flaky Test Quarantine Decisions
  • Periodically review quarantined tests to ensure they get fixed, not forgotten
  • Track quarantine age and escalate long-standing flaky tests
3. Use CI Health Metrics to Drive Improvement
  • Set team goals around PR Merge to Live time and build success rates
  • Use trends to justify investment in CI infrastructure improvements
