get-post

Intent

Fetch ONE LinkedIn post with its full context (post + visible comments + visible REACTORS) from its urn (urn:li:activity:NNN) or its permalink url. Read-only. Useful to get context before replying to a comment or doing outreach, and to MINE SIGNALS: whoever reacted to the post (with their slug, to enrich via get-profile or act via connect / send-message) is a lead as strong as whoever commented. Navigates to the permalink /feed/update/<urn>/, waits for the comments to render (Voyager social detail XHR) and parses the post, the comment cards and the reactor facepile from the DOM. The param is urn: pass the urn directly; if you pass a permalink url, the extractor pulls the urn out of it with the regex urn:li:activity:\d+.

To get the reactors (who reacted / liked the post), the skill opens the "Reactions" dialog itself (a read-only click on the "N reactions" summary; it never adds a reaction) and reads each row: { name, slug, reaction (Like|Celebrate|Support|Love|Insightful|Funny), degree (1st/2nd/3rd+), headline }, plus reactionsSummary (breakdown by type). The slug lets you compose with linkedin.com/get-profile(slug) or act via connect / send-message. NOTE: this returns the visible top (~10); the dialog paginates on scroll, so it is NOT the full reactor list, but it is the actionable top for outreach.
