What it does
Data Model Creation is an agent skill from Microck/ordinary-claude-skills. Optional advanced tool for complex data modeling. For simple table creation, use relational-database-tool directly with SQL statements.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).
It sits in Databases, covering Database schema design and SQL. It works with SQL and Mermaid. The repository describes itself as: An unappealing collection of Claude Skills and resources.
When your agent uses it
- Tasks that involve Database schema design
- Tasks that involve SQL
Example prompts
- “/data-model-creation”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Business Analysis Phase
- Mermaid Modeling Phase
- Model Validation Phase
What it can do on your machine
Read from SKILL.md and the folder at commit 1056d29. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are mermaid).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Data Model Creation loads about 3.4k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 1,287 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,287 words (~3,351 tokens).
“This is an OPTIONAL advanced modeling tool for complex database design. Most simple table creation should use relational-database-tool directly with SQL statements.”
