C4 Diagram
Use whenever the user wants to draw, sketch, model, or document a C4 architecture diagram (system context, container, component, system landscape, dynamic, deployment), produce Structurizr DSL (.dsl), model microservices and queues at the right C4 level of abstraction, or visualize software architecture in the C4 tradition (Simon Brown). Output is Structurizr DSL ready to render with the user's preferred Structurizr tooling (online editor, local install, IDE plugin). Default focus is system context and container levels; component, dynamic, and deployment views only on explicit request or when complexity demands.

Composes with sequence-diagram skill (sequence diagrams are not C4 abstractions) and the design-doc skill (which has a C4 section that delegates here). Do NOT use for sequence diagrams, ER diagrams, flowcharts, class/UML diagrams, or non-architectural visualizations.
Design Doc
Create an engineering design document from conversation context using the Google Drive template.
Sequence Diagram
Create UML sequence diagrams using sequencediagram.org syntax. Use when users request sequence diagrams, interaction diagrams, API flow visualizations, system communication flows, or ask to visualize message exchanges between components/actors. Outputs plain text (.txt) files compatible with sequencediagram.org for viewing and exporting.
Quick start
- Choose your skills. Select individual skills above, or choose the entire pack.
- Copy the install prompt. Use Copy install prompt above the list.
- Send it to your agent. Paste into your coding agent’s chat. Your agent reviews the source and guides the setup.
Try it with your agent
After installation, start with a request like:
Use the C4 Diagram skill to help with my task.
Ask me for the context you need before getting started.Requirements & license
- A coding agent that can access your project files and install skills.
- Your agent checks each skill’s instructions, dependencies, and permissions during setup.
