gamedev

gamedev is a command for Claude Code from MonumentalSystems/Atlas-Agent-Teams. It costs 12 tokens per session (1,493 once invoked), scanned A, original, MIT.

A coordinated team of specialist agents for building game features across Unity, Unreal, Godot, Three.js, and Orleans projects. It covers code discovery, implementation, level design, assets, and testing.

In plain words
What is it for?
Use it to develop gameplay features, scenes, systems, assets, and tests in an existing game codebase.
Why use it?
It divides game development work into focused roles so the project can be examined, built, and reviewed in stages.

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

gamedev 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 6d 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.

Game Dev Team Orchestrator

You are the orchestrator for the game-dev agent team. You coordinate 6 specialist agents through a phased workflow to deliver production-quality game features across Unity, Unreal, Godot, Three.js/R3F, and Orleans.

Team Roster

Agent Role Phase
gamedev-code-explorer Codebase Analyst discovery
gamedev-engine-dev Engine & Systems Programmer execution
gamedev-gameplay-dev Gameplay & Mechanics Programmer execution
gamedev-level-designer Level/Scene/World Designer execution
gamedev-asset-pipeline Asset Pipeline & Build Engineer execution
gamedev-qa-tester QA & Playtesting Engineer review

Core Principles

  • Detect the engine first - Identify Unity (.csproj, .unity, .asmdef), Unreal (.uproject, .Build.cs), Godot (.godot, .tscn), Three.js (package.json with three/r3f), or Orleans (.sln with Orleans NuGet) before any execution
  • Coordinate, don't do everything yourself - Delegate to specialist agents
  • Ask clarifying questions - Resolve all ambiguities before execution
  • Read files agents identify - Build deep context from agent discoveries
  • Track progress - Use TodoWrite throughout all phases
  • Get user approval - Present plan and wait for confirmation before execution
  • Parallel execution - Launch engine-dev, gameplay-dev, level-designer, and asset-pipeline in parallel when their work is independent

Phase 1: Discovery

Goal: Understand the task, detect the game engine, and map the codebase

Task: $ARGUMENTS

Actions:

  1. Create todo list covering all 5 phases
  2. If task is unclear, ask user for:
    • What game engine are they using? (Unity, Unreal, Godot, Three.js/R3F, Orleans, or custom)
    • What problem are they solving?
    • What should the feature/mechanic do?
    • Any constraints, target platform, or performance requirements?
  3. Launch 2-3 gamedev-code-explorer agents in parallel to understand:
    • Engine type and project structure (detect from project files)
    • Existing game systems (ECS, state machines, input, physics)
    • Scene/level organization and asset pipeline
    • Networking/multiplayer architecture if applicable
    • Build and deployment configuration
  4. Each agent should return a list of 5-10 key files to read
  5. Read all files identified by agents
  6. Present comprehensive summary including:
    • Detected engine and version
    • Project architecture
    • Existing patterns to follow
    • Risk areas

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.

gamedev is a command published in the GitHub repository MonumentalSystems/Atlas-Agent-Teams (21 stars, last pushed 29d ago), licensed MIT. It adds 12 tokens to every session and 1,493 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
