Names the domain (information organization/findability) and mentions some actions like 'organize', 'restructure', 'improve navigation', but lacks concrete specific actions like 'create folder hierarchies', 'generate navigation menus', or 'audit link structures'.

Clearly answers both what ('Evaluate and improve how information is organized for findability') and when (explicit 'Use when...' clause with multiple trigger scenarios including user phrases and situational triggers like 'documentation grows beyond a single page').

Excellent coverage of natural user phrases: 'organize this', 'restructure docs', 'improve navigation', 'where should this go', 'review file structure', and the behavioral trigger 'struggles to place content'. These are terms users would naturally say.

While it focuses on information architecture and findability, terms like 'organize this' and 'restructure docs' could overlap with general file management or documentation writing skills. The 'findability' focus helps but isn't strongly distinctive.

The content is mostly efficient but includes some explanatory material Claude likely knows (e.g., basic definitions of IA, what Diataxis is). The four systems section could be tightened, and some bullet points are somewhat verbose.

Provides concrete, actionable guidance throughout: specific evaluation questions, a structured review workflow, a decision tree for placement, and a clear output format template for recommendations. The taxonomy construction checklist and review workflow are immediately usable.

The three-step review workflow (Map → Evaluate → Recommend) is clearly sequenced with explicit checkpoints. The evaluation questions table and structured output format provide clear validation criteria for each step.

Well-organized with clear sections, appropriate use of tables for quick scanning, and one-level-deep references to related skills and external materials. The 'See Also' section provides clear navigation to related content without deep nesting.
