The extension scrapes the post text and sends it to OpenRouter's API with carefully crafted prompts designed to generate natural-sounding LinkedIn comments. The AI is instructed to:
- Keep comments 1-2 sentences
- Avoid em-dashes, hollow openers ("Great post!"), and corporate speak
- Sound like a real person texting
- Take noticeably different angles for each suggestion
