SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you diagnose software failures, crashes, regressions, and performance slowdowns by turning symptoms into a clear root-cause investigation.

Core Features & Use Cases

It combines stack trace reading, log correlation, execution-path tracing, and hotspot analysis to narrow down where a bug starts and why it happens. Use it when an endpoint returns 500, a function behaves unexpectedly, a regression appears after recent changes, or a system gets slow under load. It is especially useful for tracing dependencies and call chains with GitNexus so you can confirm hypotheses before making a fix.

Quick Start

Use the xt-debugging skill to investigate this error, trace the failing execution path, and identify the most likely root cause.

FAQPage Schema
How do I find the root cause of a 500 error from a stack trace?

To find the root cause of a 500 error from a stack trace, this Skill traces execution paths and interprets error evidence. It correlates the stack trace with log timelines and call-chain dependencies to pinpoint the failing function.

What is the best way to debug an intermittent system failure or crash?

Debugging an intermittent system failure requires correlating logs and tracing execution paths. This Skill narrows down intermittent crashes by inspecting process-level execution, validating hypotheses, and detecting recent code changes.

How do I trace a performance bottleneck in a hot execution path?

Tracing a performance bottleneck in a hot execution path involves analyzing hotspots and call chains. This Skill applies performance profiling to identify slowdowns under load and confirm the exact bottleneck location before remediation.

Does root cause analysis require any specific environment setup?

Root cause analysis using this Skill requires fresh GitNexus indexing. You need to index the repository so the Skill can perform query and context tracing, inspect process-level execution, and detect changes accurately.

Can I use this to investigate regressions after recent code changes?

Yes, you can investigate regressions after recent code changes. The Skill applies change detection to identify what altered the behavior, then traces the failing execution path to validate the hypothesis before you apply fixes.
