What problem does it solve?

This skill provides a structured approach to architecting systems using the C4 model, enabling teams to produce consistent, stakeholder-friendly diagrams from Context to Code.

Core Features & Use Cases

• C1 Context: capture system scope and external actors;
• C2 Container: define runtime boundaries and deployment units;
• C3 Components: organize internal modules for complex containers;
• Deployment & Dynamic: illustrate infrastructure and runtime interactions;
• Validation: verify models against formal C4 checklists and LikeC4 syntax.

Quick Start

1. Create 1 C1 Context view and define the system and actors.
2. Add 1 C2 Container view showing major containers and relationships.
3. Add 1-2 C3 Component views for complex containers; add deployment and dynamic views as needed.
4. Run the validation workflow (npx likec4 validate) and iterate until all checks pass.
