Names a specific domain (clippy lints) and a single action (fix warnings), but does not list multiple concrete actions or elaborate on what fixing entails (e.g., auto-apply suggestions, refactor code, suppress lints).

Describes what it does (fix clippy lint warnings) but has no explicit 'Use when...' clause or trigger guidance, which per the rubric caps completeness at 2, and the 'what' is also thin—so this lands at 1.

Includes 'clippy', 'lint', and 'warnings' which are relevant keywords, but misses common variations like 'cargo clippy', 'Rust lints', 'clippy errors', 'lint fixes', or '#[allow(...)]'.

Mentioning 'clippy' narrows the domain to Rust tooling, which is fairly distinct, but the description is brief enough that it could overlap with a general Rust code quality or linting skill.

Very lean and efficient. The one explanatory sentence about warnings vs errors is genuinely useful context that prevents a common mistake. Every other token is actionable.

Provides exact, copy-paste ready commands for both the auto-fix step and the manual inspection step. The grep/sort pipeline is a concrete, executable command.

Steps are clearly sequenced (auto-fix first, then manual fix), but there's no validation/verification step after manual fixes to confirm all warnings are resolved. A feedback loop (fix -> re-run clippy -> verify clean) is missing.

This is a simple, single-purpose skill under 50 lines. The content is well-organized into clear sequential sections with no need for external references.
