Test it

Using "c4-architecture". Create architecture documentation for an e-commerce platform with web, API, order, inventory, payment, and database services.

Expected outcome:

Produces a context view for shoppers and external providers, plus a container view for services, databases, queues, and API relationships.

Using "c4-architecture". Diagram the sign-in flow for a web application using an API, auth service, and user database.

Expected outcome:

Produces a Dynamic diagram with numbered steps from browser submission through credential validation and database lookup.

Using "c4-architecture". Document production deployment for a cloud service running behind a load balancer with application and database tiers.

Expected outcome:

Produces a Deployment diagram showing browser, cloud boundary, load balancer, runtime containers, and data tier relationships.

What You Can Build

Document a Product Architecture

Create context and container diagrams that explain a product to engineers, leaders, and stakeholders.

Map a Microservices Platform

Show services, databases, queues, external systems, and ownership boundaries for a distributed platform.

Explain Production Deployment

Describe cloud, Kubernetes, or regional deployment structure with clear C4 Deployment diagrams.

Try These Prompts

Start a Context Diagram 
Create a C4 Context diagram for this system: [system name]. Include users, external systems, and main relationships.
Document Containers 
Create a C4 Container diagram for [application]. Show deployable units, databases, queues, technologies, and relationship labels.
Add Component Detail 
Create a C4 Component diagram for [container or feature]. Include only components that clarify responsibilities and data flow.
Model Deployment and Flow 
Create C4 Deployment and Dynamic diagrams for [workflow]. Show infrastructure nodes, runtime containers, and numbered request steps.

Best Practices

  • Start with Context and Container diagrams before adding lower-level detail.
  • Use clear names, technology labels, and action-based relationship labels.
  • Keep each diagram focused and split large systems into separate views.

Avoid

  • Do not model classes or libraries as deployable containers.
  • Do not show internals of external systems that your team does not own.
  • Do not create arbitrary C4 levels outside the standard model.

Frequently Asked Questions

What does this skill create?
It creates C4 architecture documentation using Mermaid diagram syntax and short explanatory context.
Which C4 levels are supported?
It supports Context, Container, Component, Dynamic, and Deployment diagrams.
Can it document microservices?
Yes. It includes guidance for service boundaries, team ownership, queues, topics, and event-driven flows.
Does it run external commands?
No evidence found. The skill files only contain markdown guidance and Mermaid examples.
Where should generated docs go?
The skill recommends files under docs/architecture with names for context, containers, components, deployment, and dynamic flows.
Does it replace architecture review?
No. It helps create clear diagrams, but human review is still needed for correctness and risk decisions.
