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: 1 finding, 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 →
- high Privilege Escalation · line 33 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
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 | $0.00096 | $0.01429 |
| Opus 5 | $0.00048 | $0.00714 |
| Sonnet 5 | $0.00019 | $0.00286 |
| Haiku 4.5 | $0.00010 | $0.00143 |
Grade A, and why
koin 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 9d 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.

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Koin Dependency Injection (Android and KMP)
Pragmatic Kotlin DI. Koin vs Hilt: Koin runs in commonMain (Hilt doesn't) and verifies the graph via verify() instead of codegen; Hilt is Android-only with codegen + deep Jetpack integration (@HiltViewModel / hiltViewModel()). This reference covers the traps and boundaries, not the Classic DSL basics (single / factory / scoped / viewModel { } with get() resolution and runtime params, koinViewModel / koinInject, startKoin { androidLogger(); androidContext(this@MyApp); modules(...) }). Related: android-skills:kmp-ktor, android-skills:android-data-layer. Deps via koin-bom: koin-core, koin-android, koin-androidx-compose, koin-compose-viewmodel (KMP), koin-compose-viewmodel-navigation (Nav 3), koin-test, + optional koin-annotations / koin-ksp-compiler.
KSP Annotations — the generated-module accessor
@Module @ComponentScan discovers annotated classes and emits a module you pass to startKoin as UserModule().module — the generated .module extension on the annotated class is the part most often missed. Pick one style per module (don't mix Classic DSL + annotations inside a single module; switching between modules is fine).
@Single class UserRepositoryImpl(private val service: UserService) : UserRepository
@Factory class UserFormValidator
@KoinViewModel class UserDetailViewModel(
@InjectedParam private val userId: String,
private val repository: UserRepository,
) : ViewModel()
@Module @ComponentScan("com.example.feature.user") class UserModule
// startKoin { modules(UserModule().module) }
KMP source-set layout
Most bindings live in commonMain; platform-typed ones (HTTP engine, Context, Keychain) go behind expect val platformModule: Module with an actual per platform (mirrors android-skills:kmp-ktor's engine pattern). iOS startup: call InitKoinKt.doInitKoin(config: nil) from iOSApp.init() — Swift reserves init, hence the do prefix.
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.

koin is a skill published in the GitHub repository rcosteira79/android-skills (136 stars, last pushed 14d ago), licensed MIT. It adds 96 tokens to every session and 1,429 once invoked, about $0.0005 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.
