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: 5 findings, up to high
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 | $0.00257 | $0.04981 |
| Opus 5 | $0.00129 | $0.02491 |
| Sonnet 5 | $0.00051 | $0.00996 |
| Haiku 4.5 | $0.00026 | $0.00498 |
Grade A, and why
widgetkit 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.
How it starts
The opening of the file, as written. The whole thing — 380 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WidgetKit (iOS)
Timeline-driven glanceable UI for Home Screen, Lock Screen, StandBy, and Control Center. Widgets are SwiftUI views rendered by a separate extension process from snapshots your app supplies ahead of time — they are not live; you push data via timelines and reloads. Grounded in Apple's WidgetKit, App Intents, and SwiftUI.
- Related surfaces: real-time updating UI (delivery, timers, scores) →
activitykit(Live Activities / Dynamic Island). The intent/entity layer →app-intents. - KMP boundary: the widget extension links the shared framework directly, or reads data the main app wrote to a shared App Group container. Keep formatting/money logic in
commonMainand hand the extension plain values; seekmp-ios-integrationandkmp-money.

Extension setup & App Groups
- Add a Widget Extension target (File ▸ New ▸ Target ▸ Widget Extension). It ships as an app extension inside your app bundle; it runs in its own sandboxed process with a tight memory limit.
- The widget process cannot reach your app's in-memory state or its private container. Share data through an App Group:
- Enable the App Groups capability on both the app and the extension targets with the same
group.<reverse-dns>id. UserDefaults(suiteName: "group.com.acme.app")for small values, or the shared file container:
- Enable the App Groups capability on both the app and the extension targets with the same
What ships with it
3 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.

widgetkit is a skill published in the GitHub repository TalissonVitorino/kmp-ios-skills (12 stars, last pushed 16d ago), licensed MIT. It adds 257 tokens to every session and 4,981 once invoked, about $0.0013 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-new
Scaffold a new MOBILE app — Android + iOS from one Kotlin/Compose Multiplatform codebase — from a bare "create a mobile app" to a green, verified build. Guardrails first: if the user already chose a different framework (React Native, Expo, Flutter, SwiftUI, native), do NOT redirect them here; if they only asked a…

Adversarial audit of one subsystem of a Kotlin/Compose Multiplatform app against its spec AND against platform semantics — the class of defect desktop-tier tests cannot see (alarms, notifications, PendingIntents, reboot, process death, DST). Use this when the user says "audit the notifications", "double check X for…

Wire a freshly scaffolded CMP/KMP app to its OWN real Firebase project — the #1 post-scaffold manual step. Use this when the user wants to connect their app to Firebase, or asks "connect my app to firebase", "set up google-services.json", "wire firebase", "create a firebase project for this app", "replace the…
