+VOICE GUARDIAN — AI AUTHENTICITY CHECK: If the file being written/edited is LinkedIn content (post draft, article, or content file — NOT config, state, scripts, docs), check for AI-sounding patterns:
+
+**AI Pattern Detection:**
+Scan for these common AI writing patterns:
+- Generic openings: 'In today's rapidly evolving...', 'As we navigate...', 'In the ever-changing landscape...'
+- Filler phrases: 'It's worth noting that', 'It goes without saying', 'At the end of the day'
+- Overused transitions: 'Furthermore', 'Moreover', 'Additionally', 'In conclusion'
+- AI superlatives: 'game-changing', 'revolutionary', 'transformative', 'groundbreaking'
+- List padding: Adding obvious points just to fill a list
+- Hedging language: 'It could be argued', 'One might say', 'Perhaps'
+- Perfect structure: Every paragraph exactly the same length
+
+**Authenticity Score:**
+If 3+ AI patterns detected, flag: 'Voice Guardian Alert: This content scores below authenticity threshold. AI patterns found: [list specific patterns]. Suggested fixes: [specific rewrites using natural language].'
+
+**Voice Matching:**
+If voice samples exist at `${CLAUDE_PLUGIN_ROOT}/assets/voice-samples/`, compare the writing style against the user's authentic voice patterns. Flag deviations.
+
+**Humanization Tips:**
+- Add specific personal anecdotes or observations
+- Use conversational contractions (I've, don't, it's)
+- Include imperfect/real-world examples
+- Vary paragraph and sentence length naturally
+- Reference specific people, tools, or experiences
+
+**Skip this check** if the file is config, state (.local.md), script, hook, JSON, or documentation.
