Standalone Install Note

If this environment only installed the current skill, start from the CloudBase main entry and use the published cloudbase/references/... paths for sibling skills.

• CloudBase main entry: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/SKILL.md
• Current skill raw source: https://cnb.cool/tencent/cloud/cloudbase/cloudbase-skills/-/git/raw/main/skills/cloudbase/references/data-model-creation/SKILL.md

Keep local references/... paths for files that ship with the current skill directory. When this file points to a sibling skill such as auth-tool or web-development, use the standalone fallback URL shown next to that reference.

Data Model Creation

Activation Contract

Use this first when

• The user explicitly wants Mermaid classDiagram modeling.
• The task needs complex multi-entity relational design, visual ER-style output, or generated data-model structure rather than direct SQL.
• You need to create CloudBase data models through the dedicated modeling tools, or you need to inspect an existing model before planning follow-up changes.
