SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Code traces without deep-diving into libraries; it explains flow from entry to output with boundary rules.

Core Features & Use Cases

  • Interactive branch navigation: trace conditionals, switches, and try/catch as user choices.
  • Stateful traces: persist progress to resume later and share insights.
  • External dependencies boundary: summarize libs without deep-tracing.

Quick Start

Follow the prompts to start tracing a target code path and select branches to explore.

Frequently Asked Questions about code-trace

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I trace code execution paths in JavaScript and Python?

Trace code execution paths by interactively navigating from entry points to outcomes, covering conditionals, loops, and async flows in JavaScript, TypeScript, and Python codebases.

Can I trace async code flows without deep-diving into external libraries?

Yes, trace async code flows while applying boundary rules that summarize external dependencies without deep-tracing them, focusing entirely on your application's logic.

How do I explore conditional branches during a code trace?

Explore conditional branches by selecting user choices interactively, allowing you to navigate switches and try/catch blocks step-by-step to understand specific execution routes.

Does tracing TypeScript code execution require any special environment setup?

Tracing TypeScript code requires a front-end interface for prompts, access to source files, and a memory store to persist trace state, enabling you to resume progress later.

What is the best way to share insights from a complex code flow trace?

Share insights from code flow traces by utilizing the stateful trace feature, which persists your interactive branch navigation progress to resume later or share with collaborators.

Why should I not trace external dependencies when debugging application code?

Avoid tracing external dependencies to prevent overwhelming complexity, as boundary rules summarize libraries instead of deep-tracing them, keeping the focus on your application code.
