plantuml-manipulator

What problem does it solve?

This Skill automates the complex and often error-prone task of managing and updating numerous PlantUML sequence diagrams. It eliminates the need for manual, repetitive edits across dozens of files when introducing new system components, business rules, or validation steps, thereby saving significant time and ensuring documentation consistency.

Core Features & Use Cases

• Batch Structural Changes: Effortlessly insert code blocks after specific groups or add new participants across multiple PlantUML files simultaneously.
• Automated Validation: Automatically check if all diagrams conform to required structures, such as the presence of specific groups or participants.
• Comprehensive Reporting: Generate detailed overviews of groups and participants within your diagrams, aiding in analysis and maintenance.
• Use Case: Imagine a new compliance requirement dictates adding a 'Data Anonymization' step to 20 different process diagrams. Instead of manually editing each file, this Skill can insert the required PlantUML block into all relevant diagrams with a single command, ensuring every diagram is updated correctly and consistently.

Quick Start

Use the plantuml-manipulator skill to insert the content of 'snippets/new-validation.puml' after the group 'Process request' in all PlantUML files within the 'processes/' directory. Ensure to skip files that already contain 'Perform validation' and create backups of the original files.
