Turn repo-local browser multiplayer game design docs into execution-ready sprint and task Markdown artifacts. Use when Codex needs to read docs/game-design/*, compose Colyseus, Excalibur, and Pixel Lab implementation guidance, and create or update docs/sprints game-slug sprint and numbered task files for building a game without implementing code.

Package, publish, update, and verify this Bun + Vite + Colyseus browser multiplayer game on itch.io. Use when Codex needs to help prepare an itch.io HTML5 build, add build:itch or package:itch scripts, build with VITE_GAME_SERVER_URL and Vite --base ./, create the HTML5 ZIP, use butler, configure the itch.io project page, run iframe smoke checks, or troubleshoot itch.io asset paths, WebSocket, wss, indexing, draft, restricted, public, or release checklist issues.

Use this skill when building, reviewing, debugging, or integrating Pixel Lab API workflows for game-ready pixel art assets, especially in Bun or TypeScript game projects. Covers Pixellab characters, rotations, animations, tilesets, map objects, UI assets, image conversion, async jobs, credential-safe token handling, complete asset-batch manifests, output provenance, and engine integration review.

Prepare, configure, deploy, and verify this Bun + Colyseus + Vite multiplayer game on Railway. Use when Codex needs to help with Railway deployment for this repo, including Dockerfile and .dockerignore setup, Railway game-server and web service settings, DB_FILE_NAME volume persistence, VITE_GAME_SERVER_URL wiring, Railway CLI commands, health checks, logs, smoke tests, or single-replica Colyseus deployment constraints.

Use this skill when brainstorming, defining, scoping, documenting, or planning a browser multiplayer game before implementation. Covers game vision, design pillars, genre and game type selection, player verbs, core loops, MDA, characters, world, mechanics, multiplayer ownership, Excalibur client architecture, Colyseus server authority, Pixel Lab asset planning, prototype slices, game design documents, GDD-style Markdown anchors, and docs/game-design planning artifacts.
