LinkedIn Reply Handler

Drafts a reply to a specific LinkedIn comment, or sweeps an entire comment thread (every top-level comment and its replies) from just the post URL and drafts a reply to each one worth answering. Both modes correctly handle LinkedIn's 2-level thread flattening: if you're replying to a reply, the Publora API needs the TOP-level comment URN as parentComment, not the reply's URN.

When to use

Single comment:

• User pastes a LinkedIn comment URL (contains ?commentUrn=...) and says "reply to this"
• An author replied to the user's comment and the user wants to continue the thread
• User wants to re-engage a conversation that's gone dormant

Whole thread (just a post URL, no comment URLs):

• User pastes a post URL and says "reply to all the comments", "clear my inbox on this post", "draft replies for everyone who commented", "sweep the comments on this post"
• User wants to catch up on a post that has accumulated comments over several days

Not for:

• Commenting on someone else's post (not replying to comments on the user's own post) → linkedin-comment-drafter
• Reading engagement without drafting anything → linkedin-engager-analytics or linkedin-thread-monitor

Input

Either shape works:

• A LinkedIn URL containing commentUrn=urn:li:comment:(activity:POST,COMMENT_ID), either the direct comment permalink or a feed URL with the query fragment. Triggers single-comment mode.
• Just a LinkedIn post URL, in any of the standard shapes (see root SKILL.md URL table), no comment URLs needed. Triggers whole-thread mode.

Output

Single comment:

• 1-2 reply drafts, 150-300 chars each
• Reaction suggestion for the comment being replied to (always react before replying)
• Thread context summary (who said what, when)
• Approval card → on user "post", fires reaction + reply via Publora
