Conciseness

The body is lean and rule-driven with minimal padding, assuming Claude's knowledge of the IntelliJ guidelines; only the nested build-scripts sub-bullets and the rustrover carve-out could be marginally tightened.

Actionability

Rules are concrete and executable (2 spaces, 140 chars, specific API annotations, exact method preferences), though it is guidance rather than copy-paste code, leaving minor gaps.

Workflow Clarity

This is a single-purpose, simple ruleset skill (under 50 lines) where the single action — apply these style rules — is unambiguous; the simple-skill exception applies and there are no destructive or batch operations requiring validation.

Progressive Disclosure

No bundle files exist and none are needed; the content is well-organized into Language and Formatting sections and stays appropriately short, satisfying the simple-skill exception for progressive disclosure.

Specificity

The description names the domain and several concrete actions ('writing or reviewing code for style compliance', 'style compliance') tied to specific IntelliJ rules, though it leans slightly on the overall body's specifics rather than fully enumerating them in the description itself.

Completeness

It has both a clear 'what' (Code style rules for IntelliJ codebase) and an explicit 'when' (Use when writing or reviewing code for style compliance); the 'when' is explicit and present but could be marginally more specific.

Trigger Term Quality

Natural trigger phrases like 'writing or reviewing code', 'style compliance', and 'IntelliJ codebase' are present and would be naturally spoken, though it lacks a few synonyms or file-extension variants.

Distinctiveness Conflict Risk

The IntelliJ-specific framing gives it a clear niche distinct from generic linting/formatting skills, with only minor overlap risk with general code-style skills.
