Conciseness

The body is pure rule bullets with zero padding — "Mark experimental APIs with `@ApiStatus.Experimental`", "Line length: 140 characters max" — and assumes Claude's competence ("Use idiomatic Kotlin: extension functions, data classes, null safety"). Every token earns its place, matching anchor 5.

Actionability

Guidance is concrete and directly executable ("Use `.put()`/`.get()` instead of `[]` operator", "else/catch/finally on new lines", the `/rustrover` 4-space override), matching anchor 4. It falls short of 5 only because there is no illustrative before/after snippet for the brace rule and "Use idiomatic Kotlin" is high-level.

Workflow Clarity

This is a simple, single-purpose skill (apply style rules when writing or reviewing code) and the single action is unambiguous, with the one exception ("Only in `/rustrover` directory...") explicitly scoped. Per the simple-skill exception, anchor 5 applies; no validation loop is needed since the skill involves no destructive or batch operations.

Progressive Disclosure

The skill is under 50 lines with no need for external bundle files (none exist), and content is organized into clear Language and Formatting sections with a clearly signaled repo-doc pointer for build-scripts. Per the under-50-lines guideline, this matches anchor 5.

Specificity

"Code style rules for IntelliJ codebase" names the domain clearly but enumerates no concrete capabilities (no mention of Kotlin-first rules, formatting limits, or build-script conventions). It matches anchor 2 ("Names the domain but actions are minimal or generic") rather than 3 because no specific actions are listed.

Completeness

Both parts are explicitly stated: the "what" ("Code style rules for IntelliJ codebase") and an explicit "Use when..." clause ("Use when writing or reviewing code for style compliance"). The "when" is generic rather than concrete, matching anchor 4 rather than 5, and it is well above anchor 3 since the trigger guidance is explicit, not implied.

Trigger Term Quality

Relevant keywords are present ("IntelliJ", "code", "style", "style compliance", "writing or reviewing"), but common variations users would naturally say — "formatting", "lint", "Kotlin", "Java" — are absent. This matches anchor 3 ("Some relevant keywords but missing common variations or synonyms") rather than 4.

Distinctiveness Conflict Risk

The IntelliJ anchor gives it a clear niche with distinct triggers, but "style compliance" phrasing overlaps generic lint/format skills, matching anchor 4 ("Mostly distinct; minor overlap risk with closely related skills") rather than 5.
