awesome-gamedev-agent-skills vs elephant-goldfish-model
awesome-gamedev-agent-skills: A collection of 76 game-development Agent Skills (SKILL.md files) plus a router skill. The router detects your engine from project files, reads the request, and loads only the matching engine, discipline and genre skills before the agent writes code. Skills are version-pinned to stated engine releases and checked by a validator.; elephant-goldfish-model: Elephant-Goldfish Model (EGM) is a Google plugin of skills for drafting design specs with a context-rich agent and stress-testing them with fresh zero-context subagents before any code is written. It installs into Antigravity, Claude Code and Codex, and walks through brainstorm, draft and review steps while you approve the trade-offs.
TL;DR
Giving Claude Code, Cursor or Codex engine-specific knowledge while building a game
Writing a design doc before building a feature with an agent
