Your starting prompt

COPY → PASTE → BUILD

Paste this into Claude Code with universal-modder installed.

Use universal-modder to plan a small Darkest Dungeon mod for my own offline single-player PC copy. Plan one original trinket as a data-only mod; validate its identifiers and avoid modifying the original files. 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.
