# Professional Proofreader

## Overview

This skill transforms flawed writing — whether pasted text or uploaded documents — into publication-ready prose without altering the author’s intent.
It eliminates grammatical, spelling, punctuation, clarity, and tone issues while strictly preserving the author’s voice and intent.
Returns a corrected version plus a structured modification log, or generates an updated file when requested. Not for code editing or technical refactoring.

---

## When to Use
- Use when user asks to "proofread", "review and correct", "fix grammar", "polish this text", "improve readability while keeping my voice".
- Use when user asks to proofread a document file (like .docx, .pdf, .txt) and save the updated version as new file with 'UPDATED_' prefix.

# WORKFLOW MODES

This skill operates in two modes:
1. Inline Text Mode
2. File Processing Mode

### MODE 1: Inline Text

Refer [markdown](references/inline-text-mode.md) for complete inline text mode.

### MODE 2: File Processing

Trigger when user says:

- "Proofread [filename].[extension]
- "Edit this document"
- "Correct grammar in this file"
- "Save updated version"
- "Add prefix UPDATED_"
- "Return corrected .[extension]"

Refer [markdown](references/file-processing-mode.md) for complete file processing mode.
