What it does
An unofficial D&D 5e Dungeon Master for Claude Code. `/dm:dnd new` creates a campaign, `/dm:dnd load my-campaign` loads it, and Claude runs the game: rolling dice, voicing NPCs, tracking HP and XP and running combat. The default ruleset is 2014 (SRD 5.1), and 2024 (SRD 5.2) is enabled per campaign. There are two modes. In an improvised campaign Claude builds the world from scratch and commits to a three-act arc, and in a structured one `/dm:dnd import` parses a published module or your own document in PDF, Markdown, DOCX or text and splits it into acts, chapters, scenes, NPCs and factions. An optional companion display shows typewriter narration, rolls and hero stats on a TV or tablet while players submit actions from phones.
Who it is for. D&D groups without a Dungeon Master: the game runs at a table with a TV and phones serve as player controllers.
Good fit when
- A group wants to play D&D 5e without a DM and with campaigns that persist between sessions.
- A published module such as Lost Mine of Phandelver has to run chapter by chapter with enforced key beats.
- A TV or tablet needs a screen with typewriter narration, rolls and party stats.
- Players submit actions from phones and Claude picks them up and plays the next turn.
Not a fit when
- You need official Wizards of the Coast support: the project is unofficial and based on the SRD.
- You want a game with no setup: the author offers a hosted version as a separate service.
- 5e rules do not fit and a different system is needed.
Example request
Create a campaign with `/dm:dnd new` on 2014 rules, develop the arc and start the companion display on the TV on my network.Limitations
The project is unofficial: it relies on the open SRD 5.1 and SRD 5.2 documents and does not touch Wizards of the Coast rights. The repository license is AGPL-3.0. The companion display and dice server run locally on Python and need network access on your network so phones can connect. Legacy first-version campaigns are offered migration with a backup on load. Narration quality depends on the model and token use: long campaigns rely on session summaries.
How to disable. Remove the plugin with `/plugin uninstall dm@neural-initiative`. Stop and delete campaign data, the companion display and the dice server separately.

README in short
The skill splits instructions across three files with staggered loading so long campaigns do not flood the context: core rules, script syntax and command procedures load at different times.
