Conciseness

Efficient overall — specific thresholds (48.dp, < 4 levels, 100 lines) and commands earn their tokens — but the Philosophy bullets ('Good UX is invisible; it just works', 'Motion provides context') are motivational padding, and ktfmtFormat is repeated in both Constraints and the VERIFY step. Matches the 'efficient; minor instances of over-explanation that could be trimmed' anchor, not level 5 which requires every token to earn its place.

Actionability

Fully executable guidance throughout: copy-paste-ready commands ('./gradlew ktfmtFormat', './gradlew lintDebug', './gradlew testDebugUnitTest') and concrete Compose code ('AnimatedVisibility(enter = fadeIn(), exit = fadeOut())', 'MaterialTheme.spacing.medium') plus a worked PR title ('feat: add fade transition to Library item selection') covering the common cases. Not level 4 because there are no pseudocode or missing key details.

Workflow Clarity

A clear five-step sequence (OBSERVE → SELECT & PROPOSE → CRAFT → VERIFY → PRESENT) with an explicit user-approval checkpoint and verification commands in VERIFY. Falls short of level 5 because there is no error-recovery feedback loop (what to do when lintDebug or testDebugUnitTest fails) and the verification steps are listed without an explicit 'only proceed when green' checkpoint.

Progressive Disclosure

The body is ~49 lines, single-purpose, well-sectioned (Goal, Constraints, Instructions, Examples), and needs no external reference files — the only mentioned path (.agents/skills/artisan/journal.md) is a one-level-deep, clearly signaled journal. Under the simple-skill guidance this matches the top anchor; not level 4 because nothing that belongs in a separate file is inlined.

Specificity

Lists multiple specific concrete actions — 'extract hardcoded styles to AppTheme, add TalkBack semantics, implement AnimatedVisibility or micro-animations, extract stateless Composables, and add @Preview annotations' — with comprehensive coverage of the Compose UI-polish domain. Not level 4 because coverage has no notable gaps; not below because every action is concrete rather than generic.

Completeness

Clearly answers 'what' ('Elevates the Jetpack Compose user interface through micro-UX improvements, animations, accessibility (a11y) fixes, and UI structural polish') and 'when' via the explicit 'Use this skill to extract... add... implement...' clause with concrete trigger phrases. Not level 4 because the when-clause is explicit and action-specific rather than vague or only weakly implied.

Trigger Term Quality

Good keyword coverage including natural user-facing terms like 'micro-UX improvements', 'animations', 'accessibility (a11y) fixes', 'UI structural polish', and 'TalkBack semantics'. A few natural phrasings users might say ('polish the UI', 'clean up the Compose code', 'improve accessibility') are only partially covered, matching the 'a few natural terms missing' anchor rather than the comprehensive level 5.

Distinctiveness Conflict Risk

'Jetpack Compose' plus 'TalkBack', 'AnimatedVisibility', 'Composables', and '@Preview' pin a clear niche with distinct, Compose-specific triggers and minimal conflict risk against generic Android or frontend skills. Not level 4 because the triggers are domain-exclusive rather than overlapping with closely related skills.
