Why This Exists

Building a game solo with AI is powerful — but a single chat session has no structure. No one stops you from hardcoding magic numbers, skipping design docs, or writing spaghetti code. There's no QA pass, no design review, no one asking "does this actually fit the game's vision?"

OpenCode Game Studios solves this by giving your AI session the structure of a real studio. Instead of one general-purpose assistant, you get 48 specialized agents organized into a studio hierarchy — directors who guard the vision, department leads who own their domains, and specialists who do the hands-on work.

100% Free — Works with OpenCode's Big Pickle model (no API costs).

Collaboration Protocol

Every task follows: Question → Options → Decision → Draft → Approval

• Agents MUST ask "May I write this to [filepath]?" before using Write/Edit tools
• Agents MUST show drafts before requesting approval
• Multi-file changes require explicit approval for the full changeset
• You make all final decisions — agents provide expertise, not autonomy

Configuration

Agent Permissions

Customize what each agent can do in opencode.json:

{
  "agent": {
    "game-designer": {
      "mode": "subagent",
      "model": "opencode/big-pickle"
    }
  }
}

Model Selection

All agents default to opencode/big-pickle (free). You can override per-agent:

{
  "agent": {
    "creative-director": {
      "model": "opencode/gpt-5.1-codex"
    }
  }
}
