Uml Modeling

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
lang:ruby
Design, critique, and revise UML diagrams from a modeling and communication perspective. Use when Codex is asked to create or improve UML; when the user asks for a graphical representation, diagram, schema, visual model, process map, state view, architecture view, or system representation of software/system behavior or structure; when the user does not explicitly choose UML but needs a model-like visual explanation; when Codex must autonomously choose the right UML diagram type or split across multiple UML diagrams. Use for reasoning about diagram form, abstraction level, boundaries, grouping, lifecycle/state design, behavior vs structure, interaction design, or diagnosing why a diagram feels wrong at the modeling level. This skill treats notation as the final representation, not as the core task.

What this skill does

Uml Modeling is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/uml-modeling/ and loads when your prompt matches the skill's trigger.
