Your starting prompt

COPY → PASTE → BUILD

Paste this into Claude Code with universal-modder installed.

Use universal-modder to plan a small Starfield mod for my own offline single-player PC copy. Plan a small original equipment record in the Creation Kit with a reversible test procedure. First confirm my exact game build and compatible tools, back up my saves, and explain the files you would change. Ask before installing a loader or changing game files. Stop if this requires anti-cheat or DRM bypass. Do not connect to multiplayer. Give me a reversible plan and a concrete in-game verification step.
