I don't have the specific context about "Category:Template implementation details" that you've referenced. Without seeing the actual category information or documentation, I cannot provide an accurate overview based solely on what you've provided. To write this properly, I would need you to share the category description, its purpose, or other reliable information about what this category contains and why it exists.

This category is intended to collect all "devices" (often templates themselves) that are internal implementation details of Wikipedia templates. These are not meant to be directly used by regular editors. They are sub-templates organized by a rootname of the primary template grouped in one place for the benefit of template implementors. This is, by the way, the reason why they are provided with very little external documentation.
The pages listed in this category are templates.
