A mod in
one sentence
The world of The Chest is stored as plain text: gifts, events, characters, the lore the villagers know and the wording of the chronicle. Every new mod starts with a set of instructions for an AI coding agent.
Tell your agent (Claude Code, Codex, Cursor or another) what you want. It writes the mod, checks it and runs the village with it for a few years. Steam Workshop support is planned for Early Access.
You: “Add a gift: a compass. The village should not understand it.”
$ thechest-sim mod new --id compass
compass/data/items.yaml
compass:
names: {en: "compass", ru: "компас", zh: "指南针"}
axes: {understanding: blackbox, fate: relic}
physical: {mass_g: 90, size_cm: 6}
claim_bias: {priest: 30, finder: 50}
$ thechest-sim mod check --mod compass
$ thechest-sim mod compare --mod compass --years 10
$ thechest-sim mod pack --mod compass --out workshop/
The compass is one of the examples in the modding kit. You upload to the Workshop yourself, from the game.
