What its author says it does

Copied from the file, not written here

Explain code with diagrams, analogies, and step-by-step walkthroughs. Use when the user wants help understanding a function, file, module, request flow, architecture slice, or unfamiliar codebase area, especially when a visual explanation would make the behavior easier to follow.

Code Visual Explain

Turn confusing code into a clear mental model.

Use this skill when the user asks for an explanation, walkthrough, diagram, flow, architecture overview, or "how this code works."

Workflow

1. Read the actual code first

Inspect the relevant files, types, tests, or diffs before explaining.
Anchor the explanation in real symbols, control flow, and file references.
Separate what is directly confirmed by code from what is inferred.

2. Choose the right visual

Pick the diagram style that matches the question:

flowchart for control flow, request paths, or decision branches
sequenceDiagram for interactions between services, classes, APIs, or async steps
classDiagram or a simple relationship map for structure and ownership
stateDiagram for lifecycles, modes, and transitions
Prefer mermaid but use ASCII when the concept is tiny
Use color to indicate different consepts

3. Explain in layers

Default structure:

A one or two sentence plain-English summary
A concrete analogy that maps to the real code
A diagram that shows the important moving parts
A step-by-step walkthrough of what happens
A short "gotchas" section covering edge cases, misconceptions, or easy-to-miss behavior

For larger systems, start with the overview and then zoom into the most important path.

Rules

Do not invent behavior that is not visible in the code.
Do not use an analogy without mapping it back to the actual code elements.
Keep diagrams compact and readable. Avoid decorative nodes or irrelevant branches.
If the code is ambiguous, say what is uncertain instead of pretending it is settled.
Match the depth to the user's goal: onboarding overview, bug-hunt walkthrough, or deep implementation explanation.
