SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps developers identify the root cause of consistent CI test failures by analyzing logs, bisecting commit histories, and evaluating hardware or environment factors.

Core Features & Use Cases

  • Failure Signature Extraction: Fetches and summarizes CI failure details from logs or test outputs.
  • Commit Bisection: Identifies the commit range where regressions first appeared.
  • Remote Reproduction: Assists in reproducing failures on a remote GPU server for further debugging.
  • Use Case: A developer notices a flaky test failure and uses this Skill to trace whether it's caused by code changes or hardware differences, then reproduces the issue remotely to validate fixes.

Quick Start

Use this Skill to analyze CI logs, bisect the commit history, and reproduce errors on remote host for efficient troubleshooting.

FAQPage Schema
How do I diagnose CI test regressions and find the root cause?

Diagnose CI test regressions by extracting failure signatures from logs or test outputs, bisecting the commit history to find where the regression first appeared, and evaluating hardware factors to identify the root cause.

What is the best way to trace a flaky test failure caused by code changes or hardware differences?

Trace flaky test failures by extracting failure signatures, bisecting commits to detect code regressions, and reproducing the issue on a remote GPU server to determine if hardware differences caused the failure.

Can I reproduce CI failures on a remote GPU server for further debugging?

Yes, you can reproduce CI failures on a remote GPU server. The Skill assists in remote reproduction by extracting failure signatures and evaluating hardware factors to validate fixes and enable further debugging.

How do I bisect commit histories to find where consistent CI test failures first appeared?

Bisect commit histories by extracting failure signatures from CI logs and analyzing the commit range to identify exactly where the regression first appeared for quick root cause identification.

Do I need specific hardware to reproduce issues found in CI logs?

You need a remote GPU server to reproduce issues found in CI logs. The Skill assists in reproducing failures on remote GPU hardware to evaluate environment factors and validate troubleshooting fixes.

Why does my CI test regression persist even after reverting recent code changes?

A CI test regression may persist due to hardware or environment differences rather than code changes. Extracting failure signatures and reproducing the issue on a remote GPU server helps evaluate these environmental factors.
