Create a C4 architecture diagram from structured data.

Generates diagram source code (Mermaid or PlantUML) from explicitly defined elements, relationships, and boundaries.

Args: diagram_type: C4 diagram type: context, container, component, deployment, or dynamic title: Diagram title elements: List of C4 elements, each with: type, alias, label, description, technology relationships: List of relationships, each with: source, target, label, technology, direction boundaries: List of grouping boundaries, each with: type, alias, label, element_aliases output_format: Output format: mermaid (default) or plantuml

Returns: Diagram source code in the requested format.

Scan a project directory and return a structural overview.

Returns information about the project including: detected language, framework, directory tree, dependencies, entry points, and config files. Does NOT interpret code — use this as a starting point for analysis, then read specific files to understand the architecture.

Args: project_path: Absolute or relative path to the project root directory max_depth: Maximum directory depth to scan (default: 3)

Returns: JSON object with project structure information.

Get C4 model reference documentation.

Returns documentation about C4 element types, diagram types, and relationship conventions. Use this to understand what elements are available and how to structure create_c4_diagram inputs.

Args: topic: Reference topic: elements, diagrams, relationships, or all

Returns: Markdown documentation for the requested topic.
