c3-container-design

What problem does it solve?

This Skill helps architects and developers define the "what" and "with what" of a system's deployable units (containers). It ensures clarity on technology choices, internal component organization, middleware, and inter-container communication, preventing architectural drift.

Core Features & Use Cases

• Context Inheritance: Automatically loads and verifies constraints inherited from the Context layer.
• Change Impact Analysis: Systematically analyzes how proposed changes affect the current container, its siblings, and its child components.
• Strategic Diagram Decisions: Guides the selection and placement of high-ROI diagrams (flowcharts, sequence, state) to visually clarify container architecture.
• Downstream Contract Definition: Clearly defines what the container expects from its child components, ensuring consistent implementation.
• Socratic Discovery: Uses targeted questions to refine understanding of container responsibilities, technology, and internal structure.
• Use Case: A team needs to add a new microservice. This skill guides them through defining its technology stack, internal components, and how it interacts with other services, ensuring it aligns with the overall system context.
