minecraft-imagegen
Minecraft Image Generation Skill
Use this skill when a Minecraft project needs new raster art or a visual concept that will later be refined into a resource pack, release post, store listing, or server brand asset.
Scope
Routing Boundaries
Use when: the task is generating or editing a bitmap image for a Minecraft project, such aspack.png, release art, store thumbnails, concept textures, UI mockups, or server/banner art.Do not use when: the task is deterministic resource-pack implementation work such aspack.mcmeta, block/item model JSON, blockstates, fonts, sounds, or shader files (minecraft-resource-pack).Do not use when: the task is vector/code-native UI, an existing SVG/logo system, or non-image code/assets.Do not use when: the current host does not expose built-in image generation or an equivalent image-editing tool.
Support Assets
- Read
references/prompt-patterns.mdwhen the request is underspecified or you need a stronger generation vs edit prompt shape. - Read
references/asset-recipes.mdwhen the user names a concrete deliverable such aspack.png, a release banner, a server header, or a texture concept sheet. - Use
scripts/scaffold-asset-brief.shto create a reviewable asset brief in the active workspace before generation when the task needs multiple rounds or stakeholder feedback.

minecraft-modding
Full-stack Minecraft mod development skill for both NeoForge (1.21+) and Fabric (1.21+). Scaffolds new mods, adds custom blocks, items, entities, recipes, commands, GUIs, dimensions, and data generation. Knows the NeoForge DeferredRegister + event-bus system and the Fabric Registry + ModInitializer system. Use when the user asks to create a Minecraft mod, add a feature to an existing mod, fix a mod bug, generate JSON assets/data, or migrate between modding platforms. Prefer NeoForge unless the user specifies Fabric or Multiloader.
64minecraft-testing
Write automated tests for Minecraft mods and plugins for 1.21.x. Covers NeoForge GameTests (@GameTest annotation, GameTestHelper assertions, test structure placement), Fabric game tests (fabric-gametest-api-v1), unit testing non-Minecraft logic with JUnit 5, MockBukkit for Paper/Bukkit plugin testing (mock server, mock player, event dispatching, inventory checking), integration testing with a test server via Gradle, and GitHub Actions CI workflows that run GameTests headlessly. Includes patterns for mocking registries, testing event handlers, testing commands, and test-driven development for Minecraft projects. Use when the user asks about testing Minecraft mods or plugins, writing GameTests, setting up MockBukkit, or configuring CI for Minecraft projects.
4minecraft-multiloader
Build Minecraft mods targeting both NeoForge and Fabric simultaneously using the Architectury framework for Minecraft 1.21.x. Covers Architectury project structure (common/neoforge/fabric subprojects), ExpectPlatform annotation for platform-specific implementations, shared registry via Architectury's registration API, platform-specific entrypoints, architectury-loom Gradle plugin configuration, gradle.properties for both loaders, multi-jar publishing to Modrinth and CurseForge, and avoiding common pitfalls when sharing code. Use this skill when building a mod that must run on both NeoForge and Fabric with a single shared codebase.
4minecraft-datapack
Create, edit, and debug Minecraft vanilla datapacks for 1.21.x. Covers the full datapack format: pack.mcmeta, function files (.mcfunction), advancements, predicates, loot tables, item modifiers, recipe overrides, tags, damage types, dimension types, worldgen overrides, and structure sets. Handles function syntax, execute command chains, macro functions (1.20.2+), storage NBT, scoreboard operations, advancement triggers, pack format numbers, and /reload workflow. No Java or mod loader required — pure vanilla JSON and .mcfunction files. Use when creating or editing Minecraft datapacks, writing .mcfunction files, configuring loot tables or advancements, or any vanilla datapack development that does not need mod loaders.
4minecraft-server-admin
Set up, configure, and operate Minecraft Java Edition servers for 1.21.x across Paper, Purpur, Folia, Velocity networks, and modded (Fabric/NeoForge) deployments. Covers deployment selection, performance tuning playbooks, plugin operations, proxy/forwarding setup, backup and recovery runbooks, live incident troubleshooting, Docker/Pterodactyl patterns, and security hardening. Use for server infrastructure and operations, not plugin or mod feature development.
3minecraft-ci-release
Set up CI/CD pipelines, automated publishing, and release workflows for Minecraft mods and plugins for 1.21.x. Covers GitHub Actions matrix builds for NeoForge and Fabric, automated publishing to Modrinth (via minotaur Gradle plugin) and CurseForge (via curseforgegradle), GitHub Releases with JAR artifacts, semantic versioning conventions for Minecraft mods, CHANGELOG generation, Dependabot for Gradle wrapper and plugin updates, build caching with gradle/actions/setup-gradle, pull request checks, and release tag workflows. Also covers Paper plugin CI with shadow JAR builds. Use when the task is CI/CD pipelines, release automation, artifact publishing, versioning, or release governance for Minecraft mods or plugins.
