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

sdk-version-check 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 7d 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.

Skill: SDK Version Check

Purpose

Detects apps built with outdated Xcode SDKs or targeting deprecated iOS versions, enforcing Guideline 2.5.10 which requires apps to be built with the current SDK from Xcode. Apple rejects submissions that do not meet the minimum SDK requirement enforced at each yearly iOS release cycle.

Apple Guideline

  • Primary: 2.5.10 — Performance: Current SDK
  • Related: 2.3.6
  • Reference: references/guidelines/2-performance.md

Real-World Rejection Cases

  • Case: App submitted with iOS 15 SDK (Xcode 13) after Apple began requiring iOS 16 SDK — rejected with ITMS-90725 "SDK Version Issue" Source: Apple Developer Forums (multiple annual reports at iOS SDK deadline) Root cause: Apple sets a hard deadline each spring for the minimum SDK version required for new submissions and updates — apps built against an older SDK receive an automatic rejection notice from App Store Connect before the binary even reaches human review

  • Case: App targeted iOS 12 as deployment target while referencing APIs only available on iOS 15+ without availability checks — crashed on older devices during review Source: Apple Developer Forums (Guideline 2.5.10 enforcement) Root cause: When IPHONEOS_DEPLOYMENT_TARGET is set lower than the APIs used, the app crashes at runtime on devices running the declared minimum OS — reviewers test on devices at or near the minimum supported version

  • Case: App used a deprecated UIWebView after Apple removed it from the SDK — rejected at upload with ITMS-90809 Source: Apple Developer News (UIWebView removal, April 2020) Root cause: APIs removed from the SDK cause binary validation failures at upload time — App Store Connect's automated checks reject the binary before human review begins

Trigger

Invoke on any iOS/macOS project before App Store submission to verify SDK and deployment target configuration.

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.
