SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides a focused C4 Container lens to illustrate static container boundaries, technology choices, and external integrations, helping teams communicate architecture without exposing implementation details.

Core Features & Use Cases

  • Create C4 Container diagrams that highlight containers, responsibilities, and interconnections.
  • Document technology choices and external integrations for each container.
  • Ensure diagrams are generated only after loading the mermaid skill as a mandatory prerequisite.

Quick Start

Invoke the arch-lens-c4-container skill to generate a C4 Container diagram from your static architecture.

FAQPage Schema
What is a C4 container diagram used for in software architecture?

A C4 container diagram visualizes static container boundaries, technology choices, and external integrations without exposing implementation details. It helps teams communicate architecture clearly by highlighting containers, responsibilities, and interconnections.

Can I use this to document external integrations and technology choices for each container?

Yes, loading the mermaid skill is a mandatory prerequisite before generating any container analysis diagrams. The skill ensures the final architecture visualization is output as a valid Mermaid-friendly TB diagram with properly layered sections.

What is the best way to visualize container boundaries without exposing implementation details?

Yes, you can visualize external integrations and document technology choices for each container. The generated diagram organizes containers into layered sections for application, services, packages, storage, and external systems to map interactions clearly.

Does the C4 container diagram output support layered sections for application and services?

The best way to visualize container boundaries without exposing implementation details is using a focused C4 Container lens. It illustrates static boundaries and tech choices while ensuring diagrams highlight responsibilities and interconnections rather than code-level implementation.

How do I structure a SKILL.md frontmatter for generating container architecture diagrams?

Yes, the C4 container diagram output supports layered sections for application, services, packages, storage, and external systems. It generates a Mermaid-friendly TB diagram that organizes containers and interactions into these distinct architectural layers.

How do I structure a SKILL.md frontmatter for generating container architecture diagrams?

To structure a SKILL.md frontmatter for generating container architecture diagrams, include the name and description fields. This frontmatter is required by the skill to process static architecture data and output the Mermaid container visualization.
