v3.0 is a rebuild. GameForge now installs as a real Claude Code plugin, every skill was rewritten against a shared spec and current research, and the web and AI-agent paths are first-class.
| Change | Details | |
|---|---|---|
| 🔌 | Installs as a plugin | Spec-compliant .claude-plugin/ manifests. The old claude install github:… line reinstalled the Claude Code CLI rather than GameForge; see Quick Start |
| ⚡ | 7 new skills | game-vibe-code, game-ai-assets, game-web-publish, game-multiplayer, game-help, and engine specialists for Three.js / R3F and 2D web |
| 🧠 | Studio subagents | The 11 roles run as parallel subagents with project memory; the orchestrator delegates to them for independent reviews |
| 🔬 | Every skill upgraded | Late-2026 engines and tools, an AI-agent section per role, unsourced anecdotes removed, deep material moved to on-demand references/ |
| 🛡️ | Hooks that work | Rewritten, wired and tested: session briefings, compaction recovery, commit and Git LFS guards, engine-file protection. Silent outside game projects |
| ✅ | Real validation | A plugin-aware validator, 183 hook tests on Linux, macOS and Windows, and claude plugin validate --strict in CI |
Full details: CHANGELOG.md.
1. Install (Claude Code 2.1.275 or later):
/plugin install gameforge --marketplace AlterLab-IEU/AlterLab_GameForge
Two-step install, shell install, or local development
/plugin marketplace add AlterLab-IEU/AlterLab_GameForge
/plugin install gameforge@alterlab-gameforge
claude plugin marketplace add AlterLab-IEU/AlterLab_GameForge
claude plugin install gameforge@alterlab-gameforge
git clone https://github.com/AlterLab-IEU/AlterLab_GameForge.git
claude --plugin-dir ./AlterLab_GameForge
2. Ask for directions. In any folder:
/gameforge:game-help
3. Set up a game project. In your game's repository:
/gameforge:game-start
This writes .gameforge/project.json, copies the right engine starter into CLAUDE.md, sets up
Git LFS, and turns on GameForge's session briefings. From then on, plain language works:
"design the parry system", "why is my Godot export black on iOS", "plan the next sprint".

Most new indie and jam games now involve a coding agent somewhere. GameForge treats that as a craft with rules, not a slot machine. The rules come from what worked in 2025-2026 jams and from published agent guidance, and they are written up in docs/vibe-coding.md.
Stars on GitHub
A development methodology for coding agents that makes the agent brainstorm before building, follow plans, run parallel work and finish branches in a disciplined way. You get fewer skipped steps and more consistent results from your coding assistant.
@obraHelps you take a change from a rough idea or bug report through to a tested, reviewed result, with each step handled by a focused skill. Its skills cover pinning down domain terms, designing module interfaces, diagnosing hard bugs, and reviewing changes against your repo's coding standards.
@mattpocockGives your coding agent a planning, testing and review routine to follow on every task. It plans before building, checks changes with tests, has a fresh reviewer look for regressions, and saves repeated wins as reusable skills.
@affaan-mDeveloper tools for working on the React codebase itself. Provides skills for extracting error messages, managing and debugging feature flags across release channels, running Flow type checks, and fixing lint and formatting issues before committing.
@facebookA Claude Code plugin of skills for indie game development, covering game design, art direction, audio direction, accessibility, and engine workflows, with CI validation for game design documents.
