Image Creation & Editing Skills

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.

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.

Generate Minecraft-focused raster assets with Codex's built-in image generation tool, including pack icons, promo art, concept textures, thumbnails, server banners, and UI mockups. Use when the deliverable should be a bitmap image rather than JSON models, SVG, or code-native assets.

Develop Minecraft server plugins using the Paper/Bukkit/Spigot API for Minecraft 1.21.x. Handles creating Paper plugins with JavaPlugin, event listeners with @EventHandler, commands, schedulers (sync/async/Folia-safe), Persistent Data Container (PDC), Adventure text components, Vault economy integration, BungeeCord/Velocity messaging, plugin.yml and paper-plugin.yml configuration, YAML config management, and Paper-specific enhancement APIs. Always targets Paper API 1.21.x (Java 21) with Gradle (Kotlin DSL). Plugins run server-side only and do not require client installation. Use when creating or modifying Minecraft server plugins, working with Paper/Bukkit/Spigot APIs, or developing server-side features involving event handlers, commands, or plugin.yml configuration.

Create custom world generation content for Minecraft 1.21.x including custom biomes, dimensions, noise settings, surface rules, placed/configured features, carvers, structure sets, and biome modifiers. Covers both the datapack-only approach (JSON worldgen files) and the mod-code approach (NeoForge BiomeModifiers, Fabric BiomeModification API, code-driven worldgen registration with DeferredRegister). Includes compact JSON patterns and validator-backed reference checks for biome, dimension, placedfeature, configuredfeature, structure, structureset, and biomemodifier files. Targets Minecraft 1.21.x with official Mojang mappings. Use when the user asks about Minecraft worldgen, custom biomes, datapack JSON for dimensions or features, or mod-based biome modification with NeoForge or Fabric.
