How to use it

Beginner for a small CSV. Specify column names, row count, allowed values and relationships, then request fictional CSV data with headers. Check row counts, dates and constraints before importing a copy into your spreadsheet. File creation and running a generated script need separate approval; a script is an output, not an automatic run.

What it asks your AI tool to do

Run commands on your computer

This is what the instructions ask for, not something LuluSkill does. In a chat window nothing runs; in an AI tool that can work with your files, what actually happens depends on that tool and its permission settings.

Pinned versionThis page describes commit c68487d721e4 of pm-execution/skills/dummy-dataset/SKILL.md. A newer version in the author’s repository is not covered until it is reviewed again.

Automated scanPassed (lowest risk), on Oct 13, 2026: 2 files checked, 0 findings. The scan looks for patterns such as shell commands, web requests, credential access and instruction overrides. It does not run the Skill and is not a full security audit.

ReviewRecorded on Oct 13, 2026 by LuluSkill’s AI project supervisor on the owner’s behalf. It checked the source, the licence file, the scan result and this description. It is not a human review and not a legal opinion.
