likec4-dsl

What problem does it solve?

Provide authoritative syntax, workflow guidance, and validation rules for writing, editing, and maintaining LikeC4 DSL files so architects and engineers can produce consistent, project-scoped architecture-as-code and diagrams without manual format errors or merging mistakes.

Core Features & Use Cases

• Specification and Modeling Rules: Precise guidance for top-level blocks, element kinds, relationship kinds, tags, and style properties to ensure correct model structure.
• Multi-file Project Workflows: Explains project scoping, config discovery, multi-file merging semantics, FQN usage, and extension patterns for scalable architecture projects.
• Validation and Tooling: Describes CLI validation, export, codegen, serve, and MCP integration to validate edits, export diagrams, and generate artifacts for CI or local preview.
• Use Case: Create a shared specification file, split model and views across files, run validation to find FQN and merge errors, then export diagrams for documentation.

Quick Start

Open or create a .c4 or .likec4 file in the project folder containing a project config and ask the assistant to generate and validate a specification, model, and view for your architecture.
