Setup Instructions

Step 1: Create Your Context Profiles

Run these skills in Claude Code to create your profiles:

1. Voice DNA: Say "Help me create my voice DNA profile"

   • Attach 3-10 writing samples
   • Claude will analyze and create your voice profile

2. ICP: Say "Help me create my ICP"

   • Answer interview questions about your audience
   • Claude will generate your ideal client profile

3. Business Profile: Say "Help me create my business profile"

   • Answer questions about your business
   • Claude will generate your business context

Step 2: Add Your Content (Optional)

Add published content to /knowledge/archive/ to help Claude:

• Learn more about your voice
• Avoid repeating content
• Reference past work for repurposing

Step 3: Start Writing

Just ask Claude to write:

• "Write me a LinkedIn post about [topic]"
• "Create 10 Substack notes from my latest newsletter"
• "Help me write a thought leadership piece on [topic]"
• "Generate a Twitter thread about [topic]"

Claude will automatically:

1. Read your context profiles
2. Find relevant skills
3. Create content in your voice

3. Build knowledge: Add more content to improve results over time
4. Be specific: Tell Claude exactly what you want
5. Give feedback: If output doesn't match, tell Claude what to adjust

The Formula

Context + Instructions = Quality Output

• Context = Your profiles in /context/
• Instructions = Skills in /.claude/skills/
• Output = Content that sounds like you
