A browser D&D 5e dungeon crawl where an AI dungeon master runs the game for a three-character party without inventing rules.
The Goblin Warren is a browser D&D game. The AI dungeon master queries two Sanity Context MCP endpoints: a knowledge base for rule prose and GROQ for exact stats. The server prefetches both, the model gets one optional tool round, and citations no lookup returned are stripped. Claude Code agents built the Sanity layer.
Rules answers came back in about 1.3–2.2 seconds. The knowledge base flagged six 2014/2024 edition conflicts in its own entries for review.
Use an org token with the Context Viewer role. A project token returns 403 contextGrantRequired, which cost the author an hour. The knowledge base is capped at roughly 150 documents.
Act as the dungeon master for a D&D 5e dungeon crawl for a party of three: [character 1 name, class, level], [character 2 name, class, level], [character 3 name, class, level]. Use only official 5e rules, ask me to roll or make the choices, and tell me when you are unsure of a rule rather than inventing one. Run one full dungeon of about [number] rooms and end with a short recap of loot and XP.
Claude Code got an old DirectX game running on modern hardware, decompiled much of it, built a headless parallel runner, and now writes full level guides with screenshots.
An agent runs overnight, collects the author's AI newsletter subscriptions and produces a daily podcast to listen to on walks.
Commenters use agents for weekly meal planning, daily briefs, errand tracking, email sorting, home repair load and household task organization.
