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: 2 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 | $0.00186 | $0.04673 |
| Opus 5 | $0.00093 | $0.02337 |
| Sonnet 5 | $0.00037 | $0.00935 |
| Haiku 4.5 | $0.00019 | $0.00467 |
Grade A, and why
app-intents 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 12d 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 — 447 lines — stays where its author put it; the contents beside it link to each section on GitHub.
App Intents (iOS)
Expose your app's verbs (actions) and nouns (entities) to the system so Siri,
Spotlight, the Shortcuts app, widgets, Control Center, the Action button, and
Apple Intelligence can invoke them. Pure Swift, code-first — no .intentdefinition
file and no Info.plist registration; the compiler discovers your types via the
App Intents extension metadata. Framework is iOS 16+; newer surfaces are flagged inline.
- Widget/control UI & timelines:
widgetkit(this skill covers only the configuration intent, not the view). - Live Activities driven by an intent:
activitykit(LiveActivityIntent). - Gate money-moving actions behind biometrics:
swift-security(LAContext, biometry-gated Keychain). - URL-scheme / Universal Link routing:
deep-linking. - iOS-locale formatting inside dialogs/snippets:
swift-formatstyle.
Contents
- Anatomy & when to use which protocol
- AppIntent + perform / IntentResult
- @Parameter
- AppEntity + EntityQuery
- AppShortcutsProvider (Siri phrases)
- Spotlight: IndexedEntity
- OpenIntent
- Confirmation, authentication & foreground continuation
- SnippetIntent (interactive result views)
- Widget & Control configuration intents
- Assistant schemas (Apple Intelligence, iOS 18+)
- Correctness checklist

Anatomy & when to use which protocol
| Goal | Conform to |
|---|---|
| A callable action (Shortcuts/Siri) | AppIntent |
| A model object the system can reference/pass | AppEntity (+ an EntityQuery) |
| Fixed set of choices | AppEnum |
| One or more Siri phrases, auto-registered | AppShortcutsProvider |
| Open an entity in your app | OpenIntent |
| Configure a WidgetKit widget | WidgetConfigurationIntent |
| Configure a Control Center control | ControlConfigurationIntent |
Drive a Live Activity (→ activitykit) |
LiveActivityIntent |
| Return an interactive SwiftUI snippet | SnippetIntent |
| Continue in the foreground after a partial run | ForegroundContinuableIntent |
| Be discoverable by Apple Intelligence (iOS 18+) | @AssistantIntent(schema:) / @AssistantEntity(schema:) |
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.

app-intents is a skill published in the GitHub repository TalissonVitorino/kmp-ios-skills (12 stars, last pushed 17d ago), licensed MIT. It adds 186 tokens to every session and 4,673 once invoked, about $0.0009 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 2026-08-30.
Other skills, from other repositories
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…
cmp-firebase-connect
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…
cmp-audit
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…
