Document C4 Container Architecture
Container architecture documentation can become inconsistent when components, APIs, and deployment units are tracked separately. This skill helps Claude, Codex, and Claude Code synthesize components into C4 container documents, diagrams, and API summaries.

Test it
Using "c4-container". A web app, API service, PostgreSQL database, and message queue with brief component notes.
Expected outcome:
- A container summary with web, API, database, and queue responsibilities.
- A dependency list that explains user, service, database, and messaging relationships.
- A Mermaid C4Container diagram outline for the deployment view.
Using "c4-container". Several component documents and a Kubernetes deployment summary for a microservice system.
Expected outcome:
- A mapped list of components inside each deployment container.
- An interface summary with REST, event, and database interactions.
- A gap list for missing scaling, resource, and ownership details.
Using "c4-container". API notes for a container that exposes public and internal endpoints.
Expected outcome:
- A container API section with protocol, purpose, endpoint groups, and consumers.
- OpenAPI specification guidance for request parameters and response descriptions.
- Dependencies and external systems that should appear on the container diagram.

What You Can Build
Prepare service documentation
Turn component notes into clear container documentation for service ownership and onboarding.
Create API architecture notes
Document container interfaces, protocols, dependencies, and API specifications before implementation review.
Review deployment boundaries
Compare containers, databases, queues, and external systems in a shared C4 model view.
Try These Prompts
Create a first container draft
Create C4 container-level documentation for this system. Use my component list, technologies, and deployment notes. Include containers, interfaces, dependencies, and a Mermaid diagram outline.
Map components into containers
Review these component documents and group them into deployment containers. Explain each boundary, list contained components, and identify missing deployment details.
Document interfaces and dependencies
Create container interface documentation from these service notes. Include protocols, endpoints, external systems, dependencies, and OpenAPI specification guidance.
Synthesize a complete C4 package
Build a complete C4 container package from these component, API, infrastructure, and deployment inputs. Include rationale, diagrams, API summaries, scaling notes, and review gaps.
Best Practices
- Provide component documents, deployment notes, and known infrastructure constraints together.
- Keep container names aligned with real deployable units and ownership boundaries.
- Review generated diagrams with engineers who operate the services.
Avoid
- Do not use it for code-level class or function documentation.
- Do not invent containers when deployment ownership is unknown.
- Do not treat placeholder OpenAPI examples as production specifications.
Frequently Asked Questions
What C4 level does this skill focus on?
It focuses on the Container level, where deployable units, data stores, queues, and external systems are documented.
Can it create Mermaid diagrams?
Yes. It guides Mermaid C4Container diagram structure for container-level architecture views.
Does it validate OpenAPI specifications?
No. It provides API documentation guidance, but a separate validator should check OpenAPI syntax.
What inputs work best?
Use component documents, service names, deployment notes, API summaries, dependencies, and infrastructure constraints.
Is this useful for microservices?
Yes. It is useful when services, databases, queues, and external integrations need a shared deployment view.
Can it replace architecture review?
No. It prepares consistent documentation that architects and service owners can review.
