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 | $0.00036 | $0.00777 |
| Opus 5 | $0.00018 | $0.00388 |
| Sonnet 5 | $0.00007 | $0.00155 |
| Haiku 4.5 | $0.00004 | $0.00078 |
Grade A, and why
game-performance-budget 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 8d 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 Performance Budget
Overview
Compare reproducible performance measurements with explicit budgets instead of treating a fast developer machine or average frame rate as proof.
When to use
Use for milestone gates, optimization reviews, target-hardware qualification, regression checks, memory reviews, loading tests, and network performance budgets.
When NOT to use
Do not use to guess performance without captures, to optimize before a measured bottleneck, or to certify hardware that was not tested.
Required inputs and context discovery
Collect build ID, scene or scenario, target hardware tier, quality settings, warm-up method, capture duration, measurement tool, percentile metrics, memory categories, loading phases, network conditions, and thresholds.
Safety and risk level
Read-only analysis. Profiling unavailable hardware or builds is BLOCKED; estimates may be Unverified but never PASS.
Workflow
- Define budgets per target hardware tier and gameplay scenario. Completion criterion: units, thresholds, and allowed variance are explicit.
- Validate capture identity and measurement method. Completion criterion: build, settings, warm-up, duration, and profiler source are recorded.
- Compare observed percentiles and peaks with each budget. Completion criterion: every metric reports target, observed value, delta, and verdict.
- Attribute exceeded budgets to measured subsystems or mark attribution unresolved. Completion criterion: bottleneck claims cite profiler evidence rather than intuition.
- Define optimization experiments and regression gates. Completion criterion: each action includes a metric, target, owner, and retest scenario.
Evidence and output contract
Produce performance-budget-report.json with build and hardware identity, scenarios, targets, observations, deltas, verdicts, profiler artifacts, limitations, and retest actions.
Handoff contract
Record failing tiers, worst scenarios, capture paths, suspected subsystems, known measurement noise, owners, and exact retest commands or steps.
What ships with it
2 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.

game-performance-budget is a skill published in the GitHub repository hoatv2211/GameStudio-CodexKIT (3 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 777 once invoked, about $0.0002 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.
