 # Document Workflow（PDF/DOCX/PPTX/XLSX）
 
 ## When to Use
 
-- Extract content: text/tables/metadata/forms from PDF; structured extraction from Office docs
-- Apply edits: tracked changes/comments（docx）, slide updates（pptx）, formulas/formatting（xlsx）

 - Goal: what must change / what must be produced（include acceptance criteria）

 ## Procedure（default）
 
 1. **Triage**
-
    - Identify file types, size/page counts, and what “correct” looks like
-   - Clarify constraints (legal docs? exact formatting? formulas? track changes?)

 2. **Operate**
-
    - Keep edits scoped and reproducible (scripted steps preferred for batch ops)
    - Separate “content edits” from “format-only” changes when possible
 
 3. **Validate**
-
    - Re-open / re-parse outputs; check errors, missing assets, broken formulas
-   - For xlsx: verify no `#REF!/#DIV/0!/#NAME?` etc (and recalc if tooling supports it)
