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 | $0.00067 | $0.00409 |
| Opus 5 | $0.00034 | $0.00204 |
| Sonnet 5 | $0.00013 | $0.00082 |
| Haiku 4.5 | $0.00007 | $0.00041 |
Grade A, and why
app-clips 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 2d 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
App Clips
APP CLIPS: SETUP: Requires separate App Clip target (kind: "app_clip" in plan extensions array). App Clips are a lightweight version of your app for quick, focused tasks.
INFO.PLIST (auto-configured on App Clip target in project.yml): NSAppClip dict with NSAppClipRequestEphemeralUserNotification and NSAppClipRequestLocationConfirmation is set automatically. No manual configuration needed.
ASSOCIATED DOMAINS (auto-configured in project.yml entitlements): appclips:{bundleID} and parent-application-identifiers are set automatically.
APP CLIP EXPERIENCE URL: Configure in App Store Connect. Users launch App Clip via NFC, QR code, Maps, etc.
APP CLIP INVOCATION (receive URL): struct AppClipApp: App { var body: some Scene { WindowGroup { ContentView() .onContinueUserActivity(NSUserActivityTypeBrowsingWeb) { activity in guard let url = activity.webpageURL else { return } // Handle URL: extract parameters, show relevant content } } } }
SKOverlay (promote full app from within App Clip): import StoreKit @Environment(.requestAppStoreOverlay) var requestOverlay Button("Get Full App") { requestOverlay(AppStoreOverlay.AppClipCompletion(appIdentifier: "YOUR_APP_ID")) }
CONSTRAINTS:
- App Clip binary must be < 15 MB
- No access to HealthKit, CallKit, SiriKit (use App Intents in full app)
- Limited background modes
- Use @AppStorage for lightweight persistence (no SwiftData)
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.

app-clips is a skill published in the GitHub repository Abdullah4AI/apple-developer-toolkit (10 stars, last pushed 5d ago), licensed MIT. It adds 67 tokens to every session and 409 once invoked, about $0.0003 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.
