SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill consolidates systematic debugging methodologies to tackle hard bugs that resist quick fixes, helping engineers identify root causes and reduce debugging time.

Core Features & Use Cases

  • Rubber Ducking: verbalize the logic and compare expected versus actual behavior to reveal discrepancies.
  • Code Flow Tracing: trace data through each transformation from input to output to identify where expectations diverge.
  • Hypothesis Testing: generate 3-5 possible causes and 3-5 assumptions, then test to eliminate them.
  • Logging: insert targeted logs at decision points and async boundaries to aid diagnosis, with cleanup after validation.
  • Agent Investigation: spawn Explore agents to trace a specific code path and report back; use multiple advisor perspectives when stuck.
  • Before Fixing: verify exact failing lines and understand why it fails before making changes.
  • Related: Frontend Debugging

Quick Start

Start a debugging session by articulating a failing hypothesis, tracing the data flow from entry to failure, and adding minimal, targeted logs to capture key states.

FAQPage Schema
How do I debug hard-to-find bugs caused by asynchronous behavior or state mutations?

To debug hard-to-find bugs caused by asynchronous behavior or state mutations, use structured workflows like generating 3-5 hypotheses, tracing code flow, and inserting targeted logs at async boundaries to identify where expectations diverge.

What is the rubber ducking technique for software debugging?

Rubber ducking is a software debugging technique where you verbalize the code logic and compare expected versus actual behavior to reveal discrepancies that expose the root cause.

What's the best way to trace data through unfamiliar code paths to find a failure?

The best way to trace data through unfamiliar code paths is to follow the code flow systematically, tracking data through each transformation from input to output to identify exactly where expectations diverge.

How do I verify a failing line before applying a bug fix?

To verify a failing line before applying a bug fix, trace the exact failing lines, understand why the code fails, and test your generated assumptions to eliminate false causes before making changes.

Can I use agent-assisted investigation to debug complex code paths?

Yes, you can use agent-assisted investigation to debug complex code paths by spawning Explore agents to trace specific routes and report back, using multiple advisor perspectives when stuck.

When should I insert targeted logs during systematic debugging?

You should insert targeted logs during systematic debugging at decision points and async boundaries to capture key states for diagnosis, ensuring you clean them up after validation.
