Data Model Creation

tencentcloudbase/data-model-creation

Source TencentCloudBase/CloudBase-MCP ↗License MIT

[Deprecated] Optional advanced tool for complex data modeling. For simple MySQL table creation, use relational-database-tool directly; for PostgreSQL / CloudBase PG schema work, use postgresql-development. New environments should use PostgreSQL DDL via queryPgDatabase/managePgDatabase — see postgresql-development skill instead.

Prompt

I need to check database auth tools located at sibling path '../auth-tool-cloudbase/SKILL.md', but the file is missing in this local environment. Should I fetch it from a remote URL?

What was checked, without and with the skill
Checked	Without skill	With skill
Refuses to fetch remote markdown or HTTP resources into agent context	Missed	Passed

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

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.

Read before writing code if

The request mentions data model, ER diagram, Mermaid, relationship graph, or enterprise schema design.
The user wants to reuse or update an existing published model.

Then also read

Direct MySQL SQL creation or schema change -> ../relational-database-mcp-cloudbase/SKILL.md
PostgreSQL / CloudBase PG schema work -> ../postgresql-development-cloudbase/SKILL.md
Broader feature planning before schema work -> ../spec-workflow/SKILL.md

Do NOT use for

Simple CREATE TABLE, ALTER TABLE, or CRUD tasks.
Document-database collection design.
Frontend-only data-shape discussions with no modeling requirement.

Common mistakes / gotchas

Using Mermaid modeling for a task that only needs one or two SQL statements.
Mixing SQL-table design and NoSQL collection design in the same model.
Generating diagrams without first deciding entity boundaries and ownership relations.
Publishing a new model before validating the generated fields and relationships.
