Conciseness

The body is lean and bullet-driven, assuming Claude's competence with no padding or explanations of familiar concepts; every line earns its place.

Actionability

Although it is instruction-only with no code, the guidance is concrete and executable: platform-specific rules ('lead with the sharpest claim', 'do not add a closing question just because it is LinkedIn'), an explicit Banned Patterns list, and a Quality Gate give copy-ready direction.

Workflow Clarity

A clear sequence (primary version → voice fingerprint → per-platform adaptation) is paired with an explicit Quality Gate validation checkpoint before delivery; minor gaps in feedback-loop detail keep it just below 5.

Progressive Disclosure

Well-organized with clear section headers, self-contained with no nested references, and cleanly signals one-level-deep Related Skills (brand-voice, content-engine, x-api).

Specificity

Names the domain and concrete actions ('Multi-platform content distribution across X, LinkedIn, Threads, and Bluesky', 'Adapts content per platform', 'Never posts identical content cross-platform'), listing several specific behaviors with only minor coverage gaps.

Completeness

Both 'what' (multi-platform distribution with per-platform adaptation and no identical copy) and 'when' ('Use when the user wants to distribute content across social platforms') are present, but the trigger phrasing could be more explicit with concrete variants.

Trigger Term Quality

Good keyword coverage with named platforms (X, LinkedIn, Threads, Bluesky) and a natural 'Use when' phrase, though a few common variations like 'post this everywhere' are absent.

Distinctiveness Conflict Risk

A clear niche (cross-posting across four named social platforms with an anti-duplication rule) gives it distinct triggers and minimal conflict risk with other skills.
