SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify and diagnose root causes of bugs by guiding a structured investigation through symptoms, traces, and code paths.

Core Features & Use Cases

Phase-driven debugging that traces from user reports to underlying causes.
Cross-checks changes and evidence to avoid premature fixes.
Use cases include errors, stack traces, regressions, and intermittent failures reported by users or monitors.

Quick Start

Describe the bug and ask me to investigate the root cause before proposing a fix.

FAQPage Schema

How do I find the root cause of a bug instead of just patching the symptom?▼

Root-cause debugging requires tracing symptoms through code paths and stack traces to the underlying cause. This Skill guides a structured four-phase investigation—investigate, analyze, hypothesize, implement—with guardrails to prevent premature fixes and ensure reliable resolutions.

What is the best way to debug intermittent failures reported by automated monitors?▼

Debugging intermittent failures involves cross-checking reported symptoms, traces, and recent code changes. This Skill applies a phase-driven workflow that surfaces testable hypotheses from monitor reports, ensuring you address the actual regression rather than applying a quick patch.

How do I stop repeating bugs from recurring in my codebase?▼

Repeating bugs often stem from unaddressed root causes. This Skill diagnoses regressions and errors by guiding a structured investigation through symptoms and traces, enforcing a disciplined workflow that surfaces testable hypotheses for a reliable fix.

Can I use a structured debugging workflow for diagnosing stack traces and user-reported errors?▼

Yes, this Skill is applicable to errors, stack traces, and regressions reported by users or monitors. It guides a structured investigation through symptoms and code paths, cross-checking evidence to avoid premature fixes and deliver reliable resolutions.

Why does fixing a bug too quickly sometimes cause the same issue to reappear?▼

Quick patches often address symptoms rather than the underlying root cause. This Skill prevents repeating bugs by enforcing a four-phase investigation workflow with guardrails, ensuring you hypothesize and test the actual code path failure before implementing a fix.
