SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Understanding how a piece of code actually runs requires manually tracing entry points and call chains across files, which is slow and error-prone. This Skill combines a college-level conceptual explanation with a concrete runtime trace of the code in your own codebase. ## Core Features & Use Cases - Concept Explanation: Explains what the thing is at college level, defining terminology inline with path/to/file.ext:LINE citations on every claim. - Call Path Tracing: Lists every entry point that reaches the code in an entry-points table. - Call Tree Rendering: Shows an indented, execution-ordered call tree where every node carries a clickable file:line reference. - Use Case: Ask "explain how authentication works end to end" and receive both a conceptual explanation of the auth mechanism and the exact call path from HTTP handler down to the database query. ## Quick Start Ask the assistant to explain a concept in your codebase and show how it runs, for example: explain the request retry logic and show me its full call flow.

Frequently Asked Questions about explain-code-flow

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

FAQPage Schema
How do I trace the call flow of a function in my codebase?▼

Ask to explain the function and show how it runs. The Skill reads the implementation, lists every entry point that reaches it in a table, then renders an indented call tree ordered by execution, with a clickable file:line reference on each node.

How to understand what a piece of code does end to end?▼

Request an explanation of the concept plus its flow. You get a college-level explanation of the mechanism with terminology defined inline, followed by the call path and execution-ordered call tree showing exactly how it runs in your codebase.

Does the explanation include exact file and line references?▼

Yes. Every claim in the explanation and every node in the call path and call tree carries a relative path/to/file.ext:LINE reference, so you can click straight into the source code from any point in the output.

What triggers the code flow explanation?▼

Phrases like "explain X and show me how it runs", "explain the flow of X", or "how does X work end to end" trigger it. The Skill cannot be invoked programmatically by the model since disable-model-invocation is set.

What are the limitations of static call path tracing?▼

The trace is built by reading source code, so dynamic dispatch, reflection, and runtime-only wiring may not appear as explicit edges. It reflects what is visible in the repository's implementation files.
