File Processing Mode

What this skill does

File Processing Mode manages the complete handling of document files during content editing tasks. It reads supported file types fully before making any changes, preserving the original formatting wherever possible. The skill applies a standard proofreading workflow focused on error detection with minimal corrections, ensuring the original voice remains intact. If the user requests saving, it regenerates the file according to naming conventions, adding prefixes or other requested naming rules, and returns both a confirmation and a modification log by default.

Who it's for

This skill is designed for content managers and copy editors working with document files in formats like .docx, .txt, and text-based .pdfs who need precise control over file integrity during edits. Growth marketers and agency strategists handling branded content or CRO assets requiring careful proofreading without losing original formatting will also benefit. It suits scenarios where clear feedback on unsupported file types and detailed modification history are critical for audit and collaboration.

Key workflows

First, the skill identifies the file type and immediately informs the user if the format is unsupported, avoiding wasted effort. Next, it reads the entire file content to ensure comprehensive context before applying error detection and minimal corrections focused on preserving the original voice and style. After validation, if saving is requested, it regenerates the file while maintaining original formatting and applies user-specified naming conventions, such as prefixing the filename. Finally, it returns a confirmation message along with a modification log unless the user opts for file-only output.

Common questions

What happens if I upload an unsupported file type? The skill informs you clearly that the file is unsupported and halts processing. Does it change the original formatting of my documents? It preserves the original formatting wherever possible to maintain document integrity. Will I get a summary of the changes made? Yes, by default it provides a modification log alongside the saved file unless you request otherwise.
