Based on the content preview of the uploaded files and the given hint "Missing document", I found the following potential issues:

{
    "issue": "Missing data dictionary or description document",
    "evidence": "filename,link\n15970.jpg,http://... and id,gender,masterCategory,subCategory,articleType,baseColour,season,year,usage,productDisplayName...",
    "description": "Both files, one containing image filenames and links, and the other describing attributes like gender, category, color, and usage, lack an accompanying document explaining the meaning and context of each column. A data dictionary or a description document is essential for understanding the dataset schema, the type of data in each column, and how files relate to each other. For instance, it's not immediately clear how filenames from the first file relate to the 'id' field in the second file, or the meaning and scale of categorical values."

{
    "issue": "Missing README file",
    "evidence": "filename,link\n15970.jpg,http://... and id,gender,masterCategory,subCategory,articleType,baseColour,season,year,usage,productDisplayName...",
    "description": "There is no README file included with the dataset files. A README is crucial for providing an overview of the dataset, including its purpose, how it was collected, any known limitations or biases, how to use the files together, and attribution or citation instructions. It could also include any prerequisite knowledge or additional resources needed to understand and use the dataset effectively. Without this guidance, users might misinterpret or misuse the data."
