Conciseness

The body is dense rule-content with no padding about concepts Claude already knows and compact tree examples, but the subtree-privacy rule is restated across "Split outgrown files into private subtrees", "Keep private subtrees private", and "Put shared resources at the closest fork" (e.g., 'Only `editor-view.tsx` should import...' appears in multiple forms), which could be trimmed.

Actionability

Guidance is fully concrete for an instruction-only skill: kebab-case example names, executable file-tree patterns, an avoid/prefer TypeScript import snippet, and a 7-item Decision Checklist plus a "When Unsure" decision table that cover the common cases copy-paste ready.

Workflow Clarity

The Decision Checklist ("1. Identify the semantic concept... 7. Co-locate tests") gives a clear ordered sequence with a fallback section, but there is no verification checkpoint (e.g., confirming no other file imports a private subtree after a move), so it sits below the explicit-validation anchor 5. No destructive/batch cap applies.

Progressive Disclosure

This is a single-file skill with no bundle files; every section is a core rule that belongs inline, headers are clear (Core Rules, Decision Checklist, When Unsure), and navigation is easy, so the single-file structure is appropriately split with nothing buried.

Specificity

The description lists four concrete actions ("creating, moving, splitting, or organizing TypeScript files and folders") plus a named mechanism ("Applies fractal tree file-structuring rules"), but the closing benefit clause ("reduce the cognitive overhead of choosing where to put files") is softer and less action-like, leaving minor gaps versus the comprehensive anchor 5.

Completeness

It explicitly answers "what" ("Applies fractal tree file-structuring rules which reduce the cognitive overhead of choosing where to put files") and "when" with a concrete "Use when creating, moving, splitting, or organizing TypeScript files and folders" trigger clause, matching the top anchor rather than anchor 4 whose 'when' is weaker.

Trigger Term Quality

Natural user phrases like "creating", "splitting", "organizing", and "TypeScript files and folders" are present, but common variations are missing — notably "JavaScript" (the skill body covers it), "file structure", "naming", and "where to put files" — so it falls just short of comprehensive synonym coverage.

Distinctiveness Conflict Risk

The TypeScript/JavaScript file-placement niche with "fractal tree" framing is mostly distinct, but generic triggers like "organizing files and folders" leave minor overlap risk with general code-organization or linting skills, keeping it below the minimal-conflict anchor 5.
