Conciseness

The Kotlin pattern sections (ViewModel with StateFlow, repository with Flow, sealed Result, MockK/Turbine tests) are lean and earn their tokens, but roughly 150 lines are boilerplate Claude already knows verbatim — the full app-level 'build.gradle.kts' dependency block, the GitHub Actions CI yaml, and 'detekt.yml' — complete with time-sensitive pinned versions (compose-bom 2024.01.00, mockk 1.13.9) presented outside any 'old patterns' section. This matches anchor 3 ('mostly efficient but includes some unnecessary explanation or could be tightened'); it is not a 2 because there is no padded prose, only code.

Actionability

The code is real, executable Kotlin — a complete ViewModel/UiState pair, repository implementation, Compose screen with Scaffold, and a runnable MockK/Turbine test with the MainDispatcherRule — meeting anchor 4 ('mostly executable guidance with minor gaps'). It falls short of anchor 5 because referenced symbols (User, UserApi, UserContent, the Hilt domain modules) are never defined, so the examples are not fully copy-paste self-contained.

Workflow Clarity

There is no explicit multi-step workflow: the layering (ui -> usecase -> repository -> data) is only implied by the directory tree, and the anti-patterns list tells Claude what to avoid but not in what order to proceed or how to verify work. This sits at anchor 3 ('sequence present but checkpoints missing or implicit'); it is not a 2 because the project-structure section plus per-layer examples give a rough, coherent organization, and the testing section at least gestures at verification.

Progressive Disclosure

The body has clear section headers and a logical flow, but all ~450 lines live in SKILL.md with no bundle files — no references/, scripts/, or assets/ exist — and content that clearly belongs in separate files (the full Gradle config, CI pipeline, and detekt.yml) is fully inlined. This matches anchor 3 ('some structure but could be better organized; content that should be separate is inline'); it is not a 2 because the section structure is more than minimal and nothing is buried.

Specificity

The description names the domain ('Android Kotlin development') and lists technologies ('Coroutines, Jetpack Compose, Hilt, and MockK testing') but the only actions are the generic 'development' and 'testing' — no concrete actions like 'build Compose screens' or 'write MockK tests'. This matches anchor 2 ('Names the domain but actions are minimal or generic'); it does not reach anchor 3, which requires 1-2 concrete actions rather than a stack inventory.

Completeness

There is a reasonably clear 'what' (Android Kotlin development with a named stack), but the description itself has no 'Use when...' clause or equivalent explicit trigger guidance — that lives in a separate 'when-to-use' frontmatter field, so the description alone matches anchor 3. Per the guideline, a missing 'Use when' clause caps completeness at 3; it is not a 4 because the 'when' is entirely absent from the description text, not merely imprecise.

Trigger Term Quality

'Android', 'Kotlin', 'Coroutines', 'Jetpack Compose', 'Hilt', and 'MockK' are all natural terms users would say when needing this skill, giving good keyword coverage. It falls short of anchor 5 because common variations and file extensions like '.kt', 'Gradle', or 'Room' are missing.

Distinctiveness Conflict Risk

Naming the specific stack ('Coroutines, Jetpack Compose, Hilt, and MockK') carves out a clear niche with minimal conflict risk against general Java/Android or cross-platform skills. It is not a 4 because the framework names themselves act as distinct triggers — no closely related skill would plausibly claim this exact combination.
