SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill enables evidence-based debugging by instrumenting software to reveal actual runtime behavior rather than guesses.

Core Features & Use Cases

Instrumentation-first debugging: add logs, assertions, and traces to reveal actual runtime behavior.
Evidence-based hypothesis: collect data to explain symptoms and disprove guesses.
Cross-context debugging: applicable to CLI programs, APIs, files, and environment issues to identify root causes.

Quick Start

Reproduce the issue with instrumentation enabled to capture input values and state changes.
Insert targeted debug statements to surface function entry/exit, branches taken, and external responses.
Run, collect outputs, and form a testable hypothesis to guide fixes.

FAQPage Schema

What is evidence-based debugging and when should I use it?▼

Evidence-based debugging is a technique that instruments software to reveal actual runtime behavior instead of relying on guesses. You should use it when you need to reproduce symptoms, collect input values, and form testable hypotheses to identify root causes.

How do I debug using logs and stack traces to find a root cause?▼

To debug using logs and stack traces, reproduce the issue with instrumentation enabled to capture state changes. Insert targeted debug statements to trace function entry, exit, and branches, then collect outputs to form a testable hypothesis for your fix.

Can I use observability debugging for CLI programs and APIs?▼

Yes, observability debugging applies across cross-context environments including CLI programs, APIs, and files. It uses instrumentation to capture external responses and state changes to identify root causes in various system environments.

What is the best way to stop guessing and find the root cause of a runtime error?▼

The best way to stop guessing is to adopt an instrumentation-first approach. Add logs, assertions, and traces to your code to reveal actual runtime behavior, allowing you to collect data that proves or disproves your hypotheses.

What data do I need to reproduce symptoms and debug cross-context environments?▼

You need logs, stack traces, input values, and state changes to effectively reproduce symptoms and debug cross-context environments. This data captures the actual runtime behavior needed to form evidence-based hypotheses.
