SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The fix skill provides a rigorous workflow for diagnosing and repairing software bugs without widening the blast radius of a change.

Core Features & Use Cases

  • Root-cause analysis that separates symptoms from the actual defect.
  • Scoped implementation with behavior contracts and regression-proof testing.
  • Use it for failing tests, production incidents, broken APIs, and subtle regressions that need a minimal safe repair.

Quick Start

Ask the fix skill to investigate the bug, confirm the root cause, and implement the smallest safe repair with regression tests.

FAQPage Schema
How do I diagnose and repair software bugs from tracebacks and issue references?▼

The fix workflow diagnoses software bugs by analyzing tracebacks and issue references to isolate the root cause from symptoms. It then applies a scoped correction using behavior contracts and differential testing to ensure a minimal safe repair.

What is the best way to fix failing tests and production incidents without causing regressions?▼

Fixing failing tests and production incidents safely requires root-cause analysis and scoped implementation with behavior contracts. This approach prevents widening the blast radius of a change by validating the repair using regression-proof testing.

Can I use this bugfix workflow for broken APIs and subtle code regressions?▼

Yes, this bugfix workflow handles broken APIs and subtle code regressions by applying differential testing and behavior contracts. It validates the minimal safe repair to ensure the scoped correction resolves the defect without side effects.

How does root-cause analysis separate symptoms from the actual code defect?▼

Root-cause analysis separates symptoms from the actual code defect by investigating tracebacks and issue references to find the true origin. This enables a minimal safe repair instead of merely patching the observable symptoms of the failure.

Do I need regression-proof testing to validate a scoped correction for my code?▼

Yes, regression-proof testing is required to validate a scoped correction for your code. It confirms the bugfix resolves the defect without introducing new failures, utilizing differential testing and behavior contracts to prevent widening the blast radius.
