Agent

Plans, researches, and builds in a live Minecraft Java Edition world by routing every request to one specialty orchestrator skill (build-natural-world, build-settlement, build-structure, build-systems) that coordinates the terrain, design, system, and execution leaf skills through a single gated pipeline. Use whenever…

Agent

Orchestrates the complete, end-to-end setup of the Minecraft Java MCP stack — Minecraft Java Edition with the Fabric loader, the minecraft-java MCP mod and its Fabric API dependency, the mod's configuration, and the connection to Claude. Use when the user wants to set up Minecraft Java for AI/MCP control from scratch…

chapmanjw/minecraft-java-fabric-claude-plugin

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Orchestrates a single named or standalone structure and the ground it sits on in a live Minecraft Java world — a building, a real-world or fictional replica, a statue or monument, a player house, or a bridge as an object. Sequences design, plan, blueprint, build, grading, and one integration pass so the structure…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Orchestrates a working or connective system in a live Minecraft Java world — a redstone contraption or automatic farm, a transit line, a nether hub, a mechanism — together with its housing and right-of-way. Sequences design, functional verification, build, the terrain cuts/grades it needs, and one integration pass so…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Designs and blueprints specific named buildings and building complexes in a live Minecraft Java Edition world — real-world replicas (historical and modern), pop-culture replicas (Hogwarts, Minas Tirith), user-described originals, and generative-style fictional buildings — with deep research, advanced building…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Designs and blueprints whole cities and city districts in a live Minecraft Java Edition world — real-world replicas (modern and historical), pop-culture replicas, and original cities. Plans the urban fabric — district zoning, street hierarchy, transit, walls, and reused vernacular building modules — and defers every…

Skill Claude CodeCodex

Designs and blueprints intentionally designed outdoor space in a live Minecraft Java Edition world — formal gardens, parks, plazas, courtyards, hedge mazes, fountains, parterres, topiary, cloister gardens, estate grounds. Covers French formal, Italian, English landscape, Mughal, Japanese, Chinese, modernist, and other…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Designs and blueprints a player's base of operations in a live Minecraft Java Edition world — a place to live, store, craft, enchant, and display from — not NPC villager housing. Runs an adaptive interview, proposes ASCII / Markdown / Mermaid blueprints, iterates with the user until approved, then writes the build…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Designs and blueprints monuments, sculptures, and build-art in a live Minecraft Java Edition world — giant statues, organic creatures and dragons, abstract sculpture, pixel art and murals, large 3D text and logos. Produces solid or shell-only figurative forms with no habitable interiors, using pixel-grid image…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Designs functional, customized villages and settlements in a live Minecraft Java Edition world — hamlets of a few buildings up to standard villages of 5–15 — by reusing standard Minecraft village building types adapted to the biome and the user's request. Runs an adaptive interview, proposes layout options, iterates…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Turns a Minecraft build plan into named, reusable structure definitions saved inside the world, so build elements can be placed, copied, and iterated later without any external state. Use after planning, to create or update the structure library for a build. Part of the minecraft-builder workflow.

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Verifies a Minecraft Java Edition build in-world after each phase — checks the plan was carried out as specified, that the result fits the world cleanly (no dangling edges, blocked paths, or unintended overrides), and proposes concrete course corrections. Use after every major phase of executing a build plan, as the…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Captures build requirements for a Minecraft Java Edition world, interviews the user to resolve ambiguity, and produces a detailed, fully-resolved build plan that a small model can execute mechanically. Use when starting a new Minecraft build or feature, or when a build request must be turned into a concrete plan…

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Reviews a completed Minecraft build — the plan, the execution, what worked and what did not — and records reusable process lessons in Claude's project memory so future builds go better. Use after a build is finished or a build session wraps up. Part of the minecraft-builder workflow.

chapmanjw/minecraft-java-fabric-claude-plugin

Skill Claude CodeCodex

Executes a detailed Minecraft build plan step by step — placing, filling, cloning blocks and stamping structures exactly as specified, with no redesign or improvisation. Use to carry out a plan.toon produced by exec-plan once it is detailed enough to follow mechanically. Part of the minecraft-builder workflow.

Step 4 of 4 of the Minecraft Java MCP setup. Register the running minecraft-java MCP server (the Fabric mod) with Claude (Claude Code or Claude Desktop) so the Java world tools become available, then verify the connection with a live test call. Use when the user has the MCP server running and needs to connect Claude…

Skill Claude CodeCodex

Step 1 of 4 of the Minecraft Java MCP setup. Install Minecraft Java Edition with the Fabric loader — either a single-player client or a headless dedicated server — as the foundation the MCP mod runs inside. Use when the user wants to set up Minecraft Java for AI/MCP control from scratch, or asks how to get Fabric…

Step 3 of 4 of the Minecraft Java MCP setup. Configure the MCP mod's config.json (host, port, auth, tool categories), launch Minecraft or the dedicated server, verify the embedded MCP server is listening on /healthz, and capture the bearer token for remote setups. Use when the user has the MCP mod and Fabric API…
