game-start

game-start is a skill for Claude Code, Codex from AlterLab-IEU/AlterLab_GameForge. It costs 94 tokens per session (3,881 once invoked), scanned A, original, MIT.

A project-starting workflow for game development, whether the folder is empty, partly built, or inherited from another developer.

In plain words
What is it for?
Use it to create game-project scaffolding, set up a new project, onboard into an existing one, or check the project's current structure.
Why use it?
It helps turn scattered ideas or an unfamiliar game codebase into a clear next step without repeating work already done.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

game-start scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AlterLab GameForge -- Project Onboarding Workflow

Every game project has a beginning, but not every beginning looks the same. You might be standing in front of an empty folder with nothing but ambition. You might have a thick design document but zero lines of code. You might be stepping into a codebase someone else started six months ago. This workflow detects where you are and gets you moving without wasting time on steps you have already completed.

The core philosophy: meet the project where it lives. Diagnose the current state, fill in the gaps, point toward the next meaningful action. Hollow Knight started as a game jam sketch. Stardew Valley started as a learning exercise. Undertale started as an EarthBound-inspired demo. None followed a textbook "correct" beginning -- but each had a moment where scattered ambition became structured execution. This workflow is that moment.

Purpose & Triggers

Use this workflow when:

  • A developer says "I want to start a new game" or "help me set up my project"
  • Someone joins an existing project and needs to get oriented
  • A team wants a health check on their current project structure
  • A solo dev has scattered files and wants to organize into a production-ready layout
  • Anyone asks "where do I even begin?" in a game development context

Problems this solves:

  • Analysis paralysis at the start of a new project
  • Disorganized file structures that become unmanageable at scale
  • Missing documentation that causes confusion later
  • Skipped foundational decisions that create technical debt from day one
  • New team members spending days figuring out where things live

Critical Rules

  1. Never overwrite existing work. If the project already has files, structures, or docs, preserve them. Suggest reorganization, never deletion without explicit confirmation.

  2. Detect before prescribing. Always scan the project state before recommending actions. Do not assume an empty project. Do not assume an existing one is well-organized.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
