SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents guesswork-driven changes by guiding investigations from observed symptoms to verified root causes before any fix is proposed or implemented.

Core Features & Use Cases

  • Evidence-First Investigation: Reads failures completely, reproduces issues safely, and inspects the relevant code, configuration, and history.
  • Root-Cause Validation: Traces bad values and behavior across boundaries, forms one evidence-based hypothesis, and tests it with the smallest useful probe.
  • Controlled Remediation: Selects regression proof, applies the narrowest fix, runs targeted verification, and reports remaining risks or stalled progress.
  • Use Case: When a test intermittently fails or a build produces unexpected output, use the workflow to distinguish the originating defect from downstream symptoms before changing code.

Quick Start

Use the systematic-debugging skill to investigate the reported failure, identify and validate its root cause, and recommend the narrowest verified fix.

Frequently Asked Questions about systematic-debugging

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I find the root cause of software bugs instead of just patching symptoms?▼

To find the root cause of software bugs, you need an evidence-based investigation process that reproduces the issue, traces bad values across boundaries, and validates a single testable hypothesis before applying a fix.

What is the best way to investigate intermittent test failures and flaky behavior?▼

The best way to investigate intermittent test failures is to safely reproduce the issue and inspect relevant code, configuration, and history to distinguish the originating defect from downstream symptoms before changing code.

How do I debug build failures or unexpected output systematically?▼

To debug build failures systematically, read the failure completely, form one evidence-based hypothesis, test it with the smallest useful probe, and apply the narrowest fix with targeted verification.

Why should I validate a bug hypothesis before changing code?▼

Validating a bug hypothesis before changing code prevents guesswork-driven changes by ensuring you have regression proof and have identified the actual originating defect rather than just treating downstream symptoms.

Can I use systematic debugging for crashes across configuration and runtime boundaries?▼

Yes, systematic debugging applies to crashes, build failures, and unexpected output across code, configuration, tests, and runtime boundaries by tracing bad values and behavior across those boundaries.

What should I do if my bug investigation stalls and I cannot find a root cause?▼

If your bug investigation stalls, you should report the stalled progress and remaining risks, ensuring that any partial remediation is controlled, targeted, and supported by the evidence gathered so far.
