The skill is lean and efficient, assuming Claude's competence. It doesn't explain what Strunk's Elements of Style is beyond necessary context, and every section serves a clear purpose. The LLM-ism catalog is dense but earns its place as actionable reference.

Provides concrete, executable guidance throughout: specific rules numbered and bolded for emphasis, a detailed LLM-ism catalog with examples and fixes, a clear 4-step sharpening workflow, and a practical subagent dispatch strategy for limited context.

The sharpening workflow is clearly sequenced with explicit steps (read, cut, scan, verify). The limited context strategy provides a clear 3-step process. The 'test' at the end serves as a validation checkpoint for editing decisions.

Excellent structure with clear overview, well-organized sections, and appropriate references to external files (elements-of-style.md, RECIPE.md, related skills). The warning about token consumption is a thoughtful touch. References are one level deep and clearly signaled.

Lists multiple concrete actions: 'Apply Strunk's writing rules', 'sharpening and tightening drafts by subtraction', and specifies target content types: 'documentation, commits, error messages, UI text'.

Clearly answers 'what' (apply Strunk's rules, sharpen/tighten drafts) but lacks an explicit 'Use when...' clause. The 'when' is only implied through the content types listed.

Includes some natural terms like 'documentation', 'commits', 'error messages', 'UI text', 'drafts', but missing common variations users might say like 'edit my writing', 'improve prose', 'make it concise', 'writing style'.

The Strunk's rules reference provides some distinctiveness, but 'sharpening drafts' and 'clearer, stronger' language could overlap with general writing/editing skills. The specific mention of commits and error messages helps differentiate somewhat.
