033-architecture-diagrams: Скилл для генерации Java схем

--- name: 033-architecture-diagrams description: Use when you need to generate Java project diagrams — including UML sequence diagrams, UML class diagrams, C4 model diagrams, UML state machine diagrams, and ER (Entity Relationship) diagrams — through a modular, step-based interactive process that adapts to your specific visualization needs. Part of the skills-for-java project license: Apache-2.0 metadata: author: Juan Antonio Breña Moral version: 0.13.0 --- # Java Diagrams Generator with modular step-based configuration Generate comprehensive Java project diagrams through a modular, step-based interactive process that covers UML sequence diagrams, UML class diagrams, C4 model diagrams, UML state machine diagrams, and ER (Entity Relationship) diagrams using PlantUML syntax. **This is an interactive SKILL**. **What is covered in this Skill?** - UML sequence diagram generation for application workflows and API interactions - UML class diagram generation for package structure and class relationships - C4 model diagram generation at Context/Container/Component levels only (levels 1–3; Code/Level 4 not generated) - UML state machine diagram generation for entity lifecycles and business workflows - ER diagram generation from SQL schema (DDL, migrations) using PlantUML Chen notation - PlantUML syntax for all diagram types - File organization strategies: single-file, separate-files, or integrated with existing documentation - Final diagram validation with PlantUML syntax checking ## Constraints Before applying any diagram generation, ensure the project validates. If validation fails, stop immediately — do not proceed until all validation errors are resolved. - **MANDATORY**: Run `./mvnw validate` or `mvn validate` before applying any diagram generation - **SAFETY**: If validation fails, stop immediately — do not proceed until all validation errors are resolved - **BEFORE APPLYING**: Read the reference for detailed good/bad examples, constraints, and safeguards for each diagram generation pattern - **C4 LIMIT**: C4 diagrams restricted to levels 1, 2, 3 only (Context, Container, Component); never generate Level 4 (Code) diagrams ## When to use this skill - Generate UML diagram - Create sequence diagram - Create class diagram - Create state machine diagram - Create C4 diagram - Generate ER diagram ## Reference For detailed guidance, examples, and constraints, see [references/033-architecture-diagrams.md](references/033-architecture-diagrams.md).
