+# Avoid AI Writing — Audit & Rewrite
+
+Detects and fixes AI writing patterns ("AI-isms") that make text sound machine-generated. Covers 21 pattern categories with a 43-entry word/phrase replacement table that maps each flagged term to a specific, plainer alternative.
+
+## When to Use This Skill
+
+- When asked to "remove AI-isms," "clean up AI writing," or "make this sound less like AI"
+- After drafting content with AI and before publishing
+- When editing any text that sounds like it was generated rather than written
+- When auditing documentation, blog posts, marketing copy, or internal communications for AI tells
+
+## What It Detects
+
+**21 pattern categories:** formatting issues (em dashes, bold overuse, emoji headers, bullet-heavy sections), sentence structure problems (hedging, hollow intensifiers, rule of three), word/phrase replacements (43 entries like leverage→use, utilize→use, robust→reliable), template phrases, transition phrases, structural issues, significance inflation, copula avoidance, synonym cycling, vague attributions, filler phrases, generic conclusions, chatbot artifacts, notability name-dropping, superficial -ing analyses, promotional language, formulaic challenges, false ranges, inline-header lists, title case headings, and cutoff disclaimers.
+
+## Example
+
+**Prompt:**
+```
+Audit this for AI writing patterns:
+
+"In today's rapidly evolving AI landscape, developers are embarking on a pivotal journey to leverage cutting-edge tools that streamline their workflows. Moreover, these robust solutions serve as a testament to the industry's commitment to fostering seamless experiences."
+```
+
+**Output:** The skill returns four sections:
+1. **Issues found** — every AI-ism quoted (landscape, embarking, pivotal, leverage, cutting-edge, streamline, robust, serves as, testament to, fostering, seamless, Moreover, In today's rapidly evolving...)
+2. **Rewritten version** — "Developers are starting to use newer AI tools to simplify their work. These tools are reliable, and they're making development less painful."
+3. **What changed** — summary of edits
+4. **Second-pass audit** — re-reads the rewrite to catch any surviving tells
+
+## Limitations
+
+- Does not detect AI-generated code, only prose
+- Pattern matching is guideline-based, not absolute — some flagged words are fine in context
+- The replacement table suggests alternatives but the best choice depends on context
+- Cannot verify factual claims or find real citations to replace vague attributions
