Description
dummy-dataset is an agent skill that generates realistic dummy data for testing, development and demos. You choose the product or system, the type of data, such as customer feedback, transactions or user profiles, the number of rows, which columns to include and the constraints they should follow. The default is 100 rows. The skill outputs the data in CSV, JSON or SQL, or as a Python script that generates it, so the result can be used immediately or regenerated later. It is useful for populating a test environment, building mock data for development, or giving a demo some plausible content without using real customer records. Because the data is generated rather than copied, it avoids exposing private information from a production system. The skill is part of the pm-skills collection by phuryn and is listed on skills.sh as free.…
