Arcs Rules Assistant

A rules assistant for the board game Arcs by Buried Giant Studios, covering the base game, the Blighted Reach campaign expansion, and Leaders & Lore.

Ask it rules questions, card interactions, setup questions, or errata lookups. Answers cite official sources — rulebook, card text, FAQ, and errata — and fall back to community sources (BGG, r/Arcs) for genuinely ambiguous rulings.

How it works

The assistant runs as a Claude Code skill on your machine. One player at the table runs it locally; others ask questions verbally or via group chat and the operator relays answers.

Content is read from local clones of the official Buried Giant cards repo and rules repo, so responses are fast and consistent without hitting the web on every query.

Setup

You need Claude Code, Python 3, and PyYAML (pip install pyyaml).

Clone this repo, then run the setup script from the repo root. It clones the content repos, installs the skill into Claude Code, and builds the search indexes.

Mac/Linux:

git clone https://github.com/drybones/arcs-rules-assistant.git
cd arcs-rules-assistant
bash setup.sh

Windows:

git clone https://github.com/drybones/arcs-rules-assistant.git
cd arcs-rules-assistant
.\setup.ps1

Then restart Claude Code.

Usage

Open Claude Code in the arcs-rules-assistant directory and ask:

/arcs-rules Can I build in a system I just raided?
/arcs-rules How does the Blighted Reach Warlord card work?
/arcs-rules What happens if two players tie for an ambition?

Keeping content up to date

When Buried Giant publishes new printings or errata, re-run the setup script. It will pull the latest content, regenerate the indexes, and reinstall the skill.

Mac/Linux: bash setup.sh
Windows: .\setup.ps1
