Lean, directive bullets with no explanations of concepts Claude already knows and no padding ('Lead with the concrete thing', 'Explain after the example, not before'); every section earns its place.

Instruction-only skill with concrete, copy-ready rules (e.g., 'Delete and rewrite... generic openings like "In today's rapidly evolving landscape"' and specific voice-extraction targets); the absence of code is not penalized since the guidance is specific and actionable.

Sequenced 'Writing Process' (1-5) and 'Voice Capture Workflow' with an explicit pre-delivery 'Quality Gate' verification checklist (verify claims, remove filler, confirm voice) serving as the validation checkpoint.

Single cohesive, well-sectioned file (~80 lines of body) with clear headers and no nested references; no bundle files exist, and the content is appropriately self-contained and easy to navigate.

Lists multiple concrete actions and deliverable types ('Write articles, guides, blog posts, tutorials, newsletter issues') plus voice-capture ('distinctive voice derived from supplied examples or brand guidance'), matching the multiple-specific-actions anchor rather than the domain-only level 2.

Explicitly answers both what ('Write articles... long-form content in a distinctive voice') and when via an explicit 'Use when the user wants polished written content longer than a paragraph...' trigger clause.

Covers natural phrasings users actually say ('articles, guides, blog posts, tutorials, newsletter issues', 'polished written content'), giving broad coverage of common variations rather than a single keyword.

The voice-matching and 'longer than a paragraph' qualifiers carve a clear niche (long-form, voice-consistent writing) unlikely to trigger for unrelated code/data/document skills.
