SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps turn code-level notes into a clear component-level view so teams can understand boundaries, responsibilities, and interactions without reading every file manually.

Core Features & Use Cases

  • Component Boundary Definition: Groups related code into logical components within one container.
  • Interface and Dependency Mapping: Documents exposed operations, protocols, internal relationships, and external systems.
  • Architecture Documentation: Produces consistent C4 component diagrams and supporting docs for services, APIs, and data access layers.
  • Use Case: Use it when you need to synthesize multiple implementation files into a maintainable component model for a service or module.

Quick Start

Ask the skill to analyze the target codebase and produce component boundaries, interfaces, dependencies, and a Mermaid C4 component diagram.

FAQPage Schema
How do I create a C4 component diagram from existing code documentation?▼

To create a C4 component diagram, you synthesize code-level documentation into a component-level architecture view. This groups related code into logical components, maps their boundaries, and generates a Mermaid C4Component diagram with supporting structured documentation.

What is a C4 component diagram and when do I need one for my architecture?▼

A C4 component diagram visualizes component boundaries, interfaces, dependencies, and relationships inside a single container. You need this component-level architecture view when teams must understand service boundaries and interactions without manually reading implementation files.

How do I document component boundaries and interfaces for services and APIs?▼

You document component boundaries and interfaces by aggregating code-level sources and mapping exposed operations, protocols, and internal relationships. This produces structured documentation covering services, APIs, data access layers, and external systems within a single container.

Can I map dependencies and external systems within a single container using Mermaid?▼

Yes, you can map dependencies and external systems within a single container using Mermaid C4Component diagrams. The synthesis process documents exposed operations, internal relationships, and external system interactions to maintain a clear component model.

What is the best way to synthesize implementation files into a maintainable component model?▼

The best way to synthesize implementation files into a maintainable component model is to aggregate c4-code sources into logical components. This defines boundaries, interfaces, and dependencies while producing consistent Mermaid C4 component diagrams and supporting documentation.

Does generating C4 component documentation require manual codebase analysis?▼

Generating C4 component documentation requires analyzing the target codebase to identify component boundaries, interfaces, and dependencies. The synthesis aggregates code-level sources automatically so teams can understand interactions without manually reading every file.
