In short:
ak-document-skillsworks with office files: extracting content, creating new files, editing existing ones, filling forms, merging pages, recalculating formulas. It picks a process for each of the 4 file types and checks the output file before handing it over. If it cannot check something, it says so plainly instead of claiming it did.

Summary
Use it when you need to redline a Word contract, fill a PDF form, build a PowerPoint deck from content or a template, edit a spreadsheet with formulas, or pull tables from a PDF into Excel. The command has three parts: file type, path, action. If you only need to read, use the extract action, not edit.

B --> C["Extracted content"]
B --> D["New or edited file, checked"]
B --> E["States what could not be checked"]Four concepts to know:
| Concept | Question | Example |
|---|---|---|
| File type and action | Which file, and do you want to read it or change it? | pptx bao-cao.pptx extract only reads text and notes; edit is what opens it for changes |
| Keep what you do not touch | What must stay exactly as before after the edit? | Changing "30 days" to "60 days": only the number is struck and inserted, the rest keeps its original formatting |
| Check the output file | What evidence shows the file is right? | A merged PDF has the right page count and order; a deck is rendered and each slide inspected |
| Be honest when it cannot check | What if the machine lacks a tool? | No LibreOffice: Excel formulas are kept and references reviewed, values marked as unchecked |
When you need several file types in one go, for example PDF to Excel, the skill runs the process for each type and checks each file.
Sample prompt for redlining a contract:
/ak-document-skills docx <path contract.docx> edit
This is the other party's contract, edit with tracked changes.
Changes: payment term 30 days to 60 days, party B name to <company name>,
effective date to <date>.
Change nothing else. Done when: every item above is edited and there are no changes outside this list.This skill has no flags.
