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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00246 | $0.04810 |
| Opus 5 | $0.00123 | $0.02405 |
| Sonnet 5 | $0.00049 | $0.00962 |
| Haiku 4.5 | $0.00025 | $0.00481 |
Grade A, and why
mapkit 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 400 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MapKit & CoreLocation (iOS)
SwiftUI-first mapping, user location, geofencing, search, routing, and geocoding.
Grounded in Apple's MapKit and CoreLocation frameworks. SwiftUI Map content
builder, MapCameraPosition, MapReader, and Look Around are iOS 17+; the async
CLLocationUpdate / CLMonitor APIs are iOS 17+ (with iOS 18 service-session
changes); MKGeocodingRequest and cycling directions are iOS 26.
- KMP boundary: map UI is native iOS — put the
Mapinside a SwiftUI screen, not shared Compose. Expose only data (coordinates, a location stream) fromcommonMainvia aninterface, bound to a CoreLocationactualiniosMain; seeexpect-actualandkmp-ios-integration. - Privacy first (fintech): location is sensitive. Request the narrowest authorization that works (
WhenInUseoverAlways), support reduced accuracy, and never log or transmit coordinates without a clear user-facing reason. Purpose strings and privacy-manifest details:app-store-review.
Contents
- Info.plist / entitlements
- SwiftUI Map + content builder
- Camera (position / MapCamera / changes)
- Style, controls, selection
- MapReader + MapProxy
- CoreLocation authorization
- Live location updates (async)
- Geofencing with CLMonitor
- Place search (MKLocalSearch / completer)
- Directions (MKDirections)
- Geocoding (CLGeocoder / iOS 26 MapKit)
- Look Around
- Correctness checklist

Info.plist / entitlements
NSLocationWhenInUseUsageDescription— required for any location access; app crashes on request without it.NSLocationAlwaysAndWhenInUseUsageDescription— only if you requestAlways(background/geofencing while backgrounded).NSLocationTemporaryUsageDescriptionDictionary— keyed purpose strings for one-off full-accuracy upgrades when the user granted reduced accuracy.- Background delivery (geofencing/tracking while backgrounded): enable the Location updates Background Mode and hold a
CLBackgroundActivitySession. - MapKit rendering itself needs no entitlement; showing the blue user dot needs location authorization.
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.

mapkit is a skill published in the GitHub repository TalissonVitorino/kmp-ios-skills (12 stars, last pushed 15d ago), licensed MIT. It adds 246 tokens to every session and 4,810 once invoked, about $0.0012 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 2026-09-03.

compose-multiplatform
Use when building one shared Compose UI in Kotlin across Android, iOS, and desktop — commonMain @Composables, expect/actual, source-set placement, native interop, multiplatform ViewModel/navigation/Koin. NOT a single-platform native build (that is kotlin-android / swift-ios), and NOT Dart/Flutter cross-platform UI…
cmp-upgrade
Migrate an existing Kotlin/Compose Multiplatform (CMP/KMP) project to the next PROVEN-GREEN dependency version set. Use this when the user wants to upgrade Kotlin, KSP, Compose Multiplatform, Room, AGP, Koin, or Ktor versions in a KMP project, bump their KMP dependencies, or asks "upgrade kotlin/compose/KMP versions"…
cmp-doctor
Diagnose and heal both the toolchain AND the project a Kotlin/Compose Multiplatform (CMP/KMP) build needs. Use this when the user wants to set up or fix their CMP/KMP toolchain, install the Android SDK / AVD / emulator for KMP, install Appium and its drivers for a Compose Multiplatform app, set up JDK 17 / Xcode /…
cmp-dev-client
Run a create-cmp Compose Multiplatform app's shared UI in a live desktop window with Compose Hot Reload — the daily dev loop. Use this when the user wants to run their CMP app on desktop, preview the app while developing, iterate on Compose UI without an emulator, or asks "run my CMP app on desktop", "hot reload…
cmp-preview
THE default UI feedback loop while building or editing ANY Compose Multiplatform screen — in a stamped app, use it DURING development, not only when asked: it renders the app's REAL screens headlessly in seconds (no device, no emulator, no manual Gradle) and tells you exactly what each edit changed, so you catch your…
compose-animations
Use when writing or reviewing Jetpack Compose motion: visibility enter/exit, animating one property toward a target, color or size transitions, multiple properties from one state, switching composable content, or choosing between AnimatedVisibility, animateAsState, rememberTransition, AnimatedContent, and Crossfade.
