Scapius VS Code Extension

The official Scapius extension transforms Visual Studio Code into an interactive Architecture as Code IDE.

Installation​

Key Features​

1. Syntax Highlighting​

Full grammar-aware token coloring for entity keywords, relationship verbs, enum literals, custom attribute namespaces, and styles blocks.

2. Real-time Semantic Diagnostics​

Errors (such as duplicate entity IDs, illegal relationship source-target pairs, and date ordering issues) appear directly in your editor as red squigglies and in the Problems panel.

3. Intelligent Completions & Snippets​

Type any entity keyword (e.g. system, capability, control) or relationship verb (e.g. flows_to, mitigates) and press Tab to expand boilerplate templates.

4. Hover Documentation​

Hover over any entity keyword or relationship verb to view inline parameter definitions, allowed enum values, allowed source/target constraints, and ArchiMate mappings.

You can customize the extension behavior in .vscode/settings.json:

{
  "nexus.validation.strictMode": false,
  "nexus.formatting.indentSize": 4,
