Conciseness

The ~15-line body is lean: rules state the exact API ("repeatOnLifecycle(Lifecycle.State.STARTED)") with a one-line rationale and move on, with no padding or explanation of concepts Claude already knows; every line earns its place, matching the level-5 anchor.

Actionability

Directives are concrete and executable — the exact API signature, "observe with viewLifecycleOwner (Fragment), NOT this", and named anti-patterns ("No launchWhenStarted/Resumed") — with complete code deferred to the real references/implementation.md; it falls short of level 5 because no copy-paste example appears in the body itself.

Workflow Clarity

This is a simple standards skill with an unambiguous single directive: ALWAYS use repeatOnLifecycle(STARTED), why, and what to avoid; under the simple-skill exception a single unambiguous action with no destructive/batch operations scores 5, and the anti-patterns section adds clear boundaries.

Progressive Disclosure

The body is a concise overview with a clearly signaled, verified, one-level-deep reference ([Flow Consumption Template](references/implementation.md)); the minor gap is that the link label advertises only the flow-consumption template while the file also contains a LiveData-to-Flow migration section, leaving navigation slightly underspecified relative to the level-5 anchor.

Specificity

The description names the domain and one concrete integrated action — "Integrate ViewModel state with XML Views using Coroutines and Lifecycle on Android" — plus specific technologies, but it is a single action rather than the several concrete actions of the level-4 anchor; it sits clearly above the vague level-2 anchor.

Completeness

It explicitly answers what ("Integrate ViewModel state with XML Views using Coroutines and Lifecycle") and when ("Use when managing state with repeatOnLifecycle or lifecycle-aware coroutines in Fragment/Activity") with concrete trigger phrases, matching the level-5 anchor exactly; level 4 would require a less explicit 'when'.

Trigger Term Quality

Strong natural triggers — "repeatOnLifecycle", "lifecycle-aware coroutines", "Fragment/Activity" — are phrases a user working in this domain would actually say; common variants like launchWhenStarted or LiveData are missing, keeping it just below comprehensive level-5 coverage.

Distinctiveness Conflict Risk

It carves out a clear niche (XML Views, not Compose) and actively defers adjacent areas — "defer Compose state and generic Flow design to their specific skills" — minimizing conflict risk, which matches the clear-niche level-5 anchor.
