Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00212 |
| Opus 5 | $0.00013 | $0.00106 |
| Sonnet 5 | $0.00005 | $0.00042 |
| Haiku 4.5 | $0.00003 | $0.00021 |
Grade A, and why
gsp-compare-backends 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 9d 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.
What it actually says
Game Compare Backends
Goal
Help choose between backend profiles when the choice is genuinely uncertain.
Important warning
Compare mode usually costs more tokens and time than a single recommended route. Say this explicitly before or while using it.
Good use cases
- greenfield work where two routes appear plausibly viable
- UI-first vs world-first uncertainty
- 2D vs lightweight 3D preview uncertainty
Bad use cases
- obvious stack choice
- live-product iteration
- post-architecture situations where the real blocker is not the backend
Outputs
Follow the gsp-orchestrator output strategy:
- inline (default): present comparison results in conversation (compared options, criteria, result, why the winner won, token / cost note).
- minimal or full: update
docs/game-studio/backend-decision.md.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gsp-compare-backends is a skill published in the GitHub repository mike007jd/game-superpowers (12 stars, last pushed 4mo ago), licensed MIT. It adds 25 tokens to every session and 212 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 2026-08-31.
