Names the domain (naming) and lists the types of things it names (variable, function, class names), but doesn't describe concrete actions beyond 'suggest' - missing details like how it analyzes context, what conventions it follows, or what output format it provides.

Describes what it does (suggest better names) but completely lacks a 'Use when...' clause or any explicit trigger guidance. Per rubric guidelines, missing explicit trigger guidance caps this at 2, and the 'what' is also weak, warranting a 1.

Includes relevant terms like 'variable', 'function', 'class names' that users might mention, but misses common variations like 'rename', 'naming conventions', 'identifier', 'method names', or phrases like 'what should I call this'.

Focuses on naming specifically which provides some distinction, but could overlap with general code review skills, refactoring skills, or code quality skills that might also suggest naming improvements.

The skill is moderately verbose with extensive examples and report templates that could be condensed. While the examples are useful, the full report format template and decision tree add bulk that Claude could generate contextually.

Provides concrete, executable code examples with clear before/after comparisons. The naming conventions by language are specific and actionable, and the usage examples show exact invocation patterns.

The numbered instructions provide a clear sequence (analyze → identify → check → suggest), but lacks explicit validation checkpoints. For a naming analysis task, there's no feedback loop for verifying suggested names work in context.

This is a monolithic wall of text with no references to external files. The extensive report format, naming conventions by language, and examples could be split into separate reference files with clear navigation from a concise overview.
