Your starting prompt

COPY → PASTE → BUILD

Paste this into Claude Code with universal-modder installed.

Use universal-modder to plan a small Risk of Rain 2 mod for my own offline single-player PC copy. Plan one original item for a local solo run using only the required R2API modules; validate compatibility before implementation. 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.
