Conciseness

Tables keep most sections dense, but the "LinkedIn vs Meta / X / TikTok" positioning table restates common knowledge (LinkedIn is professional and real-name; TikTok is entertainment), the "Character Limits" and "Optimal Length" tables repeat the same 100–200 and 1,300–1,600 ranges, the 88%-mobile stat appears twice, and the ~40-line Off-Site SEO/GEO section drifts beyond post-copy creation. Mostly efficient with clear trimmable padding, matching anchor 3; not 2 because the bulk is genuinely useful reference data, not filler.

Actionability

Concrete, usable numbers throughout — 3,000-char limit, 210–235 first-line window, per-type length ranges, 1200×627 / 1200×1200 image dims, ≤10MB files, up to 20 carousel images — plus a numbered 5-item Output Format and a form-note convention. Per the instruction-skill note, absence of code is not penalized; it falls short of 5 only because there is no worked example post and some guidance stays soft ("a few, relevant" hashtags, "Often strong for reach").

Workflow Clarity

The Output Format section gives a clear numbered sequence of what to produce (first line ≤210 chars → full post with count → hashtags → image specs → form note), and post-type selection is tabulated. Checkpoints as such aren't needed since nothing is destructive or batch, so no cap applies; it is not 5 because the path from "user request" to "finished post" (pick type → match length → write hook → assemble per format) must be assembled by the reader rather than stated.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ all absent), and the ~180-line body inlines a ~40-line SEO/GEO-plus-profile-modules block that is tangential to post copy creation and belongs in a separate reference file. Section headers are clear and cross-skill references are well signaled, which lifts it above anchor 2's "minimal structure," but the single-file scope creep matches anchor 3's "content that should be separate is inline."

Specificity

The description names the domain and two concrete actions — "create LinkedIn post copy or optimize for LinkedIn" — but goes no further (no mention of articles, polls, documents, image specs, or character-count handling that the skill actually covers). This matches anchor 3 (domain plus 1-2 concrete actions, not comprehensive); it is not 4 because several specific actions are missing, and not 2 because the actions named are genuinely concrete.

Completeness

It explicitly answers both questions: what ("create LinkedIn post copy or optimize for LinkedIn") and when ("When the user wants to... Also use when the user mentions [list]") with concrete trigger phrases. This matches anchor 5 exactly; voice is third-person about the user, so no voice penalty applies.

Trigger Term Quality

Fifteen quoted trigger phrases spanning natural synonyms users would actually say ("LinkedIn post," "post to LinkedIn," "LinkedIn copy," "B2B LinkedIn," "share box," "document post," "reshare," "LinkedIn marketing"). Coverage is comprehensive with variants; not 4 because very few natural phrasings (e.g. "write a LinkedIn post," "LinkedIn ghostwriting") are missing.

Distinctiveness Conflict Risk

It carves a clear niche (organic LinkedIn content) and even handles the closest conflict explicitly — "For LinkedIn ads, use linkedin-ads" — but bare triggers like "poll," "Newsletter," and "professional post" could plausibly fire for other platforms' skills. Mostly distinct with minor overlap risk, matching anchor 4 rather than 5.
