majiayu000 OSCAL Visualizer Skill
Create visual representations of OSCAL documents to help understand control structures, relationships, and compliance status.
When to Use This Skill
Use this skill when you need to:
- Visualize control hierarchies and families
- Show component relationships
- Display implementation coverage
- Create SSP overview diagrams
- Generate assessment flow charts
- Produce compliance dashboards
✅ Data Source Principle
This skill creates visualizations from documents you provide. All diagram content reflects your OSCAL data — no compliance information is generated from training knowledge.
Diagram Types
| Type | Purpose | Best For |
|---|---|---|
| Control Hierarchy | Show control families and relationships | Catalogs, profiles |
| Component Relationships | Map components to controls | Component definitions |
| Implementation Flow | Show how controls are implemented | SSPs |
| Profile Inheritance | Display profile layering | Profiles |
| SSP Overview | System security summary | SSPs |
| Assessment Flow | Assessment process visualization | SAP, SAR |

- Parse the SSP document
- Extract control implementations
- Group by family
- Calculate percentages by status
- Generate appropriate visualization
- Include legend and summary statistics
