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 5.1 | $0.00030 | $0.00436 |
| Opus 5.5 | $0.00012 | $0.00174 |
| Sonnet 5.5 | $0.00006 | $0.00087 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
android-kmp-architecture 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 1mo 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
CIEL ADAPTATION: Android & KMP Architecture (Structural Layer)
This skill formalizes the "Structural Layer" for Android and KMP projects. It enforces module isolation and dependency inversion to ensure cross-platform portability and testability.
Recommended Module Layout
project/
├── app/ # Platform entry point (Android), DI wiring.
├── domain/ # Pure Kotlin. UseCases, Domain Models, Repository Interfaces.
├── data/ # Repository Impls, DataSources (Room/SQLDelight), Network (Ktor).
├── presentation/ # ViewModels, UI State, Flow collection.
└── core/ # Shared utilities, error types, base classes.
Dependency Rules (Immutable)
- Domain Isolation:
domainMUST NEVER depend ondata,presentation, or any platform framework. - One-Way Flow:
app->presentation->domain<-data. - Mappers: Keep mappers (e.g.,
Entity -> Domain) as extension functions in thedatalayer.
Core Patterns
- UseCase: Single business operation. Use
operator fun invokefor clean call sites. - Result/Try: Use a sealed interface (e.g.,
Result<T>) for all repository/use-case returns to avoid unchecked exceptions. - DI: Standardize on Koin (KMP-friendly) or Hilt (Android-only).
Anti-Patterns
- Context Leaking: Passing Android
Contextor framework classes into thedomainlayer. - Fat ViewModels: Putting business logic in ViewModels instead of UseCases.
- Circular Deps: Allowing
domainto know aboutdataimplementations.
What ships with it
1 file 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.

android-kmp-architecture is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 4d ago), licensed Apache-2.0. It adds 30 tokens to every session and 436 once invoked, about $0.0001 per session on Opus 5.5. 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.
