Structurizr Workspace - Created with Scaffoldizr

This skill enables agents to generate and interact with a Structurizr workspace, generated with Scaffoldizr CLI tool

When to use this skill

• Whenever the user needs to create or update elements within a given Structurizr workspace.
• Whenever the user needs to create an architecture diagram (leveraging the C4 model).
• Whenever the user needs to validate an existing Structurizr workspace.

General instructions

• In the root folder, search for an ./architecture folder. If there is no such folder, offer to create one using Scaffoldizr, run:

  scfz --dest <root_folder> \
    --workspaceName "<name>" \
    --workspaceDescription "<description>" \
    --workspaceScope "softwaresystem" \
    --systemName "<system name>" \
    --systemDescription "<system description>" \
    --authorName "<author name>" \
    --authorEmail "<author email>" \
    --shouldIncludeTheme "false"
  

  Scaffoldizr will create the ./architecture folder with all the relevant files.

NOTE: if the scfz command is not available, Scaffoldizr CLI tool is not installed. Run the appropriate installation script for the current environment:

• macOS / Linux — run in terminal:

  curl -s https://formulamonks.github.io/scaffoldizr/assets/install.sh | sh
  

• Windows — run in PowerShell:

  irm https://formulamonks.github.io/scaffoldizr/assets/install.ps1 | iex
  

Refer to the full installation instructions for more details.

Non-interactive CLI usage (AI Agent Mode)

Scaffoldizr supports non-interactive execution by specifying a generator as a subcommand and passing all prompt answers as CLI flags. This is the preferred approach for AI agents — it avoids interactive prompts entirely.

Subcommand routing

When a workspace.dsl already exists, bypass the main menu by specifying a generator subcommand:

scfz <generator> [--flag "value"]

Generator names are kebab-cased: external-system, software-system, etc.

Passing arguments

All prompt questions can be answered via CLI flags using --parameter "value" or --parameter=value format.

Element generators reference

The --viewType flag accepts landscape, deployment, or dynamic. For other view types (systemContext, container, component), create the DSL file manually following the instructions in the view reference.

• All the relevant documentation files are contained within the ./architecture folder.
• The main entrypoint is the ./architecture/workspace.dsl file.
• ./architecture/workspace.json is a compiled output generated from workspace.dsl. Never read or modify it directly — it will be overwritten the next time Structurizr runs. To regenerate it, run ./architecture/scripts/export.sh (or export.ps1 on Windows).

Folder contents

The architecture folder contains the following structure:

• ./architecture/archetypes: Elements that serve as baseline or foundations for other elements. Contains reusable relationship patterns (e.g., 1_https_relationship.dsl).
• ./architecture/containers/<system name>: Container definitions for a software system. Each software system is contained within an independent folder.
• ./architecture/components/<system name>/<container name>: Component definitions for a software system. Each software system is contained within an independent folder, as well as each container.
• ./architecture/decisions: Architecture Decision Records (ADRs) documenting key architectural decisions.
• ./architecture/docs: Documentation files referenced in the workspace.
• ./architecture/environments: This folder contains elements for Deployment view. They are used to create and display deployment diagrams.
• ./architecture/relationships: Relationship definitions for the different elements within the system.
• ./architecture/systems: System definitions. This folder also contains _people.dsl to reference person elements and _external.dsl to reference external systems (systems that are not in scope of the actual diagram).
• ./architecture/views: View definitions that render diagrams, including system context views.

Relationships in diagrams

• Structurizr DSL language has the !include directive which serves as a way to reference other files and folders. If the reference includes a file extension (e.g. file.dsl), that file at that path is included. If no extension is included, it assumes that all files within that folder are included.

Workspace Scope

• Depending on the workspace scope you are allowed to create or not certain elements. The workspace can be scoped as softwaresystem or as landscape.

  1. In both options you are allowed to create archetype, constant, view, person, external system and relationship.
  2. If it's softwaresystem you are allowed ONLY to create container, component in addition to the ones listed in point 1.
  3. If it's landscape you're allowed ONLY to create system in addition to the ones listed in point 1.

• Find what is the current workspace scope by checking the ./architecture/workspace.dsl file for the workspace block. E.g.:

workspace {
    ...
    configuration {
        scope softwaresystem  // <-- Here is where the scope is defined
    }
    ...
}

• Always alert the user when the suggested action would be in conflict with this rule.

Create new elements within the workspace

⚠️ IMPORTANT NOTE Element names have to be unique within the workspace. Before creating a new element, always check if an element with the same name already exists. If it does, propose an alternative name to the user.

Archetype

Refer to archetype documentation

Constant

Refer to constant documentation

Software System

Refer to software system documentation

External System

Refer to external system documentation

Container

Refer to container documentation

Component

Refer to component documentation

Relationship

Refer to relationship documentation

View

Refer to view

Theme

Use the theme generator to add, remove, or list workspace themes. The theme generator is available in both Landscape and SoftwareSystem scopes.

scfz theme \
  --themeAction "Add themes" \
  --additionalThemes "https://formulamonks.github.io/scaffoldizr/assets/scaffoldizr-shapes.json"

• --themeAction: "Add themes" | "Remove themes" | "List themes"
• --additionalThemes: comma-separated theme URLs to add
• Color themes (Blue, Red, Green, Yellow) are mutually exclusive — selecting a new color replaces the existing one

Use Structurizr CLI commands to interact with the workspace

Refer to CLI commands documentation

Build process

• The ./architecture/workspace.dsl is the only source of truth. All architecture changes must be made to .dsl files — never to workspace.json.
• ./architecture/workspace.json is a compiled artefact. Structurizr overwrites it on every run. ⚠️ DO NOT READ OR MODIFY ./architecture/workspace.json DIRECTLY ⚠️. Any manual edits will be silently lost.
• To regenerate workspace.json from the DSL source, run the export script:
  • Linux/macOS: ./architecture/scripts/export.sh
  • Windows: ./architecture/scripts/export.ps1
• Use ./architecture/scripts/run.sh (or run.ps1) to start Structurizr Lite and visualize diagrams at http://localhost:8080

Error Troubleshooting

Whenever the user reports an error when visualizing the Structurizr workspace, check first if you can validate reported errors with Structurizr CLI. Check here for more information. Make sure to address all issues reported by the tool before continuing.
