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.

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 | $0.00203 | $0.05017 |
| Opus 5 | $0.00102 | $0.02508 |
| Sonnet 5 | $0.00041 | $0.01003 |
| Haiku 4.5 | $0.00020 | $0.00502 |
Grade A, and why
swift-architecture scanned grade A with 1 finding 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 8d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Swift App Architecture (iOS / macOS)
Pick the smallest architecture a feature actually needs, and keep state ownership, module boundaries, and test seams explicit. Grounded in Apple's SwiftUI + Observation frameworks; TCA specifics from pointfree's swift-composable-architecture.
- KMP counterpart:
mvi-architecture— if the domain/state lives in shared Kotlin (commonMain), the iOS layer is a thin view over a shared store; don't rebuild the reducer in Swift. - State mechanics:
swiftui-observation(@Observable,@State,@Environment,@Bindabletracking rules). This skill is about structure; that one is about the machinery. - Test seams / DI:
swift-protocol-di-testing. Navigation:navigation. Concurrency in models:swift-concurrency.

Decision table
| Feature shape | Use |
|---|---|
| View maps almost 1:1 to model state; light logic | MV with @Observable |
| Non-trivial presentation logic, formatting, validation you want to unit-test off-view | MVVM (one @Observable model per screen) |
| Complex event flow, many interdependent actions, you want time-travel/replayable state | MVI (hand-rolled) or TCA |
| Large team, deep feature composition, exhaustive testing, shared conventions across many screens | TCA |
| Domain shared with Android | Domain in KMP (mvi-architecture); iOS = MV/MVVM shell |
| Business rules must outlive UI framework churn | Clean layering (use cases + repo protocols) — orthogonal to the UI pattern above |
| Flow/routing logic tangled into views | Add a Coordinator; keep the screen pattern as-is |
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.

swift-architecture is a skill published in the GitHub repository TalissonVitorino/kmp-ios-skills (12 stars, last pushed 17d ago), licensed MIT. It adds 203 tokens to every session and 5,017 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
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…
add-feature
Add a new conforming vertical-slice feature (Screen + ViewModel + UseCase + Repository + spec + tests + golden tree + nav route + DI wiring) to this Compose Multiplatform app, cloned deterministically from the project's configured exemplar feature (qa/approvals.json's exemplarFeature — home by default). Use this when…
add-screen
Add a presentation-only slice — Screen + ViewModel + tests + golden tree + spec + nav route — for an EXISTING entity/repository in this Compose Multiplatform app, cloned deterministically from the project's configured exemplar feature's presentation layer (qa/approvals.json's exemplarFeature — home by default).…
