    -H "Authorization: Bearer YOUR_API_KEY" \

## How It Works

1. Add phrases from your actual customer calls, ads, and reviews
2. Block generic AI-sounding words ("leverage", "synergy", "utilize")
3. The sequence processor and KB worker reference these when generating content
4. Custom instructions are injected into the AI system prompt

## Best Practices

* Pull words from Fathom call transcripts
* Review ad copy for brand-consistent language
* Update quarterly as your messaging evolves
