Create Clear C4 Architecture Diagrams

Architecture discussions become confusing when diagrams mix detail levels or omit relationships. This skill creates structured C4 views and reviews them against consistent guidelines.

Test it

Using "c4-modeling". Create a context view for a clinic scheduling platform used by patients and staff.

Expected outcome:

A Level 1 view centers the scheduling platform and connects patients, clinic staff, an identity provider, and a notification service with labeled relationships.

Using "c4-modeling". Expand an online store into a container view using React, Node.js, PostgreSQL, Redis, and RabbitMQ.

Expected outcome:

A Level 2 view separates the web application, API server, worker, database, cache, and queue while labeling technologies and communication paths.

Using "c4-modeling". Review a diagram that combines users, databases, API modules, and classes.

Expected outcome:

The review identifies mixed abstraction levels, recommends separate context, container, and component views, and assigns each element to the appropriate diagram.

What You Can Build

Plan a new system

Build context and container views before selecting services, data stores, and integration boundaries.

Align technical stakeholders

Present consistent architecture views that separate business context from runtime and implementation details.

Review an existing design

Check diagrams for mixed levels, missing relationships, unclear responsibilities, and unnecessary detail.

Try These Prompts

Create a context diagram

Create a Level 1 C4 context diagram for [system]. Include [users], [external systems], and labeled relationships. Ask for missing essential details.

Expand into containers

Using this approved context view, create a Level 2 container diagram for [system]. Show applications, services, data stores, queues, technologies, and relationships.

Model container components

Create a Level 3 component diagram for [container]. Include major modules, responsibilities, repositories, integrations, boundaries, and connections to other containers.

Review and refine C4 views

Review these C4 diagrams for abstraction mixing, omissions, unclear labels, and excessive detail. Return prioritized findings and revised Mermaid diagrams for each level.

Best Practices

Start with a context diagram unless an approved higher-level view already exists.
State the audience and purpose before selecting the C4 level and included details.
Give every element a clear description and every relationship a meaningful label.

Avoid

Do not create a detailed container or component view before establishing system context.
Do not combine people, containers, components, classes, and functions in one diagram.
Do not invent dependencies, technologies, or responsibilities when the source information is incomplete.

Frequently Asked Questions

Which C4 level should I start with?

Start with Level 1 context unless a current, approved context diagram already exists.

Can this skill create Mermaid diagrams?

Yes. It includes Mermaid C4 syntax for elements, boundaries, relationships, complete examples, and optional styling.

Does it support Structurizr or PlantUML?

The skill lists both formats, but its detailed syntax guidance and examples focus on Mermaid.

Can it inspect my running system automatically?

No. Provide the actors, systems, technologies, dependencies, and responsibilities that the diagrams should represent.

When should I use a code-level diagram?

Use Level 4 only for critical algorithms, key interfaces, complex data structures, or architecturally significant classes.

How does it help with architecture reviews?

It checks level selection, abstraction consistency, descriptions, relationship labels, technology choices, element counts, and boundaries.
