A DM Built with Claude

Summarizes how to build a Claude Dungeon Master skill yourself to run a persistent D&D 5e campaign, along with its architecture.

The key is designing the campaign not as a single conversation, but as a flow where state is maintained even as sessions continue. It's structured so that Claude keeps carrying forward characters, progress, and world information to perform the role of dungeon master.

The main points are as follows.

• Maintaining persistence so the campaign doesn't get interrupted
• Operating with the DM role separated out based on a skill
• Explaining the architecture suited for long-term play

This is an implementation case that treats conversational AI not as a simple responder, but as a continuous game-running engine.
