professional-proofreader – Documents & Office skill for AI agents

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.
