SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you perform disciplined root-cause debugging so you stop relying on guesswork and start producing evidence-backed explanations that prevent regressions.

Core Features & Use Cases

  • Root-cause-first workflow: Establish the earliest divergence from expected behavior before proposing any changes.
  • Evidence-driven investigation: Use differential analysis, regression hunting, and file:line-style evidence to justify conclusions.
  • Reproduction and verification loop: Build a reliable failing signal, minimize the failing case, then create/fix with a failing test and fresh verification.
  • Structured debug reporting: Emit a consistent Debug Report (and optional postmortem) to communicate SYMPTOM, ROOT CAUSE, FIX, EVIDENCE, REGRESSION, RELATED, and STATUS.

Quick Start

Ask the skill to debug a broken test or failing CLI run by sharing the full error output and steps to reproduce, then follow it to produce a root-cause statement with evidence and a verified fix plan.

FAQPage Schema
How do I find the root cause of a flaky test or intermittent bug?

To find the root cause of a flaky test, you must build a minimal deterministic reproduction loop and apply differential comparison across versions, data, environment, and timing to validate evidence-backed conclusions.

What is the best way to debug a CI failure or regression?

The best way to debug a CI failure or regression is to read full stack traces first, establish the earliest divergence from expected behavior, form ranked hypotheses, and validate one change at a time.

How do I structure a postmortem or debug report for a broken test?

To structure a debug report or postmortem for a broken test, emit a consistent format covering SYMPTOM, ROOT CAUSE, FIX, EVIDENCE, REGRESSION, RELATED, and STATUS to communicate findings clearly.

Can I use evidence-based debugging for CLI or REPL problems?

Yes, you can use evidence-based debugging for CLI or REPL problems by turning symptoms into justified conclusions using file:line-style evidence and differential analysis to pinpoint the exact failure.

Why does my test failure require a minimal deterministic repro step?

Your test failure requires a minimal deterministic repro step because it provides a reliable failing signal, allowing you to form ranked hypotheses, validate one change at a time, and prevent future regressions.

Does root-cause analysis work for triage without reading full stack traces?

No, root-cause analysis for triage requires reading full stack traces first to establish the earliest divergence from expected behavior before proposing any code changes or fixes.
