COPY → PASTE → BUILD

Paste this into Claude Code with universal-modder installed.

Use universal-modder to plan a small Cyberpunk 2077 mod for my own offline single-player PC copy. Plan a small original cosmetic change using REDmod, and verify that the requested change fits its supported scope. 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.
