AI & us – Episode #04 – Inside Claude’s Head: Secrets of the Sonnet Prompt

This week on AI & us, we dive deep into the mind of Claude Sonnet 4 – literally.
We got our hands on Claude’s secret system prompt, and we’re unpacking it all:
  •  Why Claude acts more like a thoughtful friend than a robot assistant
  •  How it coaches your prompts (without sounding like a jerk)
  •  The hardcoded rules that stop it from going full Skynet
  •  And yes… there’s poetry critique, CEO name-drops, and a strict no-lyrics policy

It’s part AI philosophy, part digital etiquette, part employee handbook – and fully fascinating.
Join us for the prompt behind the personality – and meet the Claude you didn’t see coming.
