Produces a timed 30-minute phone-screen script that balances evaluation with selling — opening, candidate story, technical calibration questions (with what each probes), role-fit questions, their-questions slot, and a post-call evaluation checklist. Use when the user says "write a phone screen", "screening script", "30-minute screen questions", or gives a role plus the technical areas to probe and selling points. Use this for the early hiring-manager screen that decides loop advancement — not for designing a coding take-home (take-home-exercise-design), nor for the full-loop debrief (interview-debrief-facilitation).
