Game Backend Selector
Goal
Select the backend profile that best serves the requested outcome.
Use ./shared/reference/backend-profiles.md.
Outputs
Follow the gsp-orchestrator output strategy:
- inline (default): present backend decisions in conversation.
- minimal or full: write
docs/game-studio/backend-decision.md.
Rules
- Prefer capabilities over brand or fandom.
- If the project already has a workable backend, bias toward it unless it is the blocker.
- Optimize for the chosen quality target, not just the fastest toy result.
- Respect project state: live iteration and greenfield do not deserve the same backend decision policy.
Compare mode
Use compare mode only when:
- the backend choice is genuinely uncertain,
- or the user explicitly requests comparison.
When compare mode is used:
- warn that it will usually cost more tokens and time,
- keep the comparison narrow,
- define the winner criteria before exploring.
Specialist follow-through
After choosing a backend profile, route to a concrete specialist when needed:
gsp-web-2d-specialist for web-2d-ui-first or web-2d-world-first
gsp-web-3d-specialist for web-3d-preview
Top-level planning remains stack-neutral.
Implementation guidance should still become concrete once a backend family is chosen.
