I'd gently suggest reconsidering this approach. Here's why:

**It undermines trust** - Threatening to replace someone creates defensiveness, not goodwill. People negotiate because it's normal and healthy, not because they're being unreasonable.

**It often backfires** - Top talent may walk away rather than accept an offer from someone who threatens them. You lose the person you wanted.

**It's inaccurate** - Most jobs have nuance, context, and judgment that AI can't replicate in 5 minutes. If it genuinely could, the role probably isn't strategic enough to fight for anyway.

**Better framing:**
- "Here's my final offer based on [market rate/budget/role parameters]"
- "I value you, and this is what I can do"
- "If this doesn't work, I understand, but this is where I need to land"

Strong negotiators actually respect directness and honesty more than pressure tactics. If someone's asking for something genuinely unreasonable, say that clearly. If it's reasonable, find a way to work with it or be clear about constraints.

You probably *want* people who negotiate—it means they know their value and will push for results.
