C4 Code Level: [Directory Name]

Use this skill when

• Working on c4 code level: [directory name] tasks or workflows
• Needing guidance, best practices, or checklists for c4 code level: [directory name]

Do not use this skill when

• The task is unrelated to c4 code level: [directory name]
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Overview

• Name: [Descriptive name for this code directory]
• Description: [Short description of what this code does]
• Location: [Link to actual directory path]
• Language: [Primary programming language(s)]
• Purpose: [What this code accomplishes]

Code Elements

Functions/Methods

• functionName(param1: Type, param2: Type): ReturnType
  • Description: [What this function does]
  • Location: [file path:line number]
  • Dependencies: [what this function depends on]

Classes/Modules

• ClassName
  • Description: [What this class does]
  • Location: [file path]
  • Methods: [list of methods]
  • Dependencies: [what this class depends on]

Dependencies

Internal Dependencies

• [List of internal code dependencies]

External Dependencies

• [List of external libraries, frameworks, services]

Relationships

Optional Mermaid diagrams for complex code structures. Choose the diagram type based on the programming paradigm. Code diagrams show the internal structure of a single component.

Object-Oriented Code (Classes, Interfaces)

Use classDiagram for OOP code with classes, interfaces, and inheritance:

---
title: Code Diagram for [Component Name]
---
classDiagram
    namespace ComponentName {
        class Class1 {
            +attribute1 Type
            +method1() ReturnType
        }
        class Class2 {
            -privateAttr Type
            +publicMethod() void
        }
        class Interface1 {
            <<interface>>
            +requiredMethod() ReturnType
        }
    }

    Class1 ..|> Interface1 : implements
    Class1 --> Class2 : uses
