The body is lean and task-specific, deliberately mirroring create-x-content to avoid restating shared logic, and does not explain concepts Claude already knows (e.g., what LinkedIn is).

Although instruction-only, the guidance is concrete and copy-ready: a framings table with structures and use-cases, specific defaults (arrow bullets, 150–500 words), a frontmatter template, a file-naming convention, and worked examples.

The six phases are clearly sequenced, and Phase 4 is an explicit self-check validation gate with seven concrete checks and remediation guidance ('If yes, rewrite to sound like a human practitioner') before outputs are saved.

It is a single self-contained file with well-organized sections and clear headings, and references to sibling skills are one level deep and clearly signaled; no nested or monolithic references to penalize.

The description lists multiple concrete actions ('Draft voice-tuned LinkedIn post variants', 'produces 2–5 variants with distinct framings', 'applies LinkedIn-specific defaults', 'self-checks against the voice guide's banned phrases'), matching the highest anchor.

It clearly answers 'what' the skill does, but lacks an explicit 'Use when…' trigger clause telling Claude when to invoke it; per the judging guidelines a missing explicit trigger caps completeness at 2.

It includes relevant natural terms ('LinkedIn post variants', 'free-form brief', 'voice guide') but does not cover common variations users might say (e.g., 'LinkedIn posts', 'social posts', 'write a LinkedIn update'), so coverage is good but not comprehensive.

The LinkedIn-specific framing plus the voice-guide dependency carve out a clear niche with distinct triggers, making it unlikely to fire for the wrong sibling skill.
