linkedin-reply-handler

# LinkedIn Reply Handler Drafts a reply to a specific LinkedIn comment. Correctly handles 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 - 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 ## Input 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. ## Output - 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 ## Steps 1. **Parse the URL.** `lib.url_parser.parse_linkedin_url` returns `post_urn`, `comment_id`, `comment_urn`. 2. **Determine thread structure.** If `APIFY_TOKEN` is set, call `lib.ApifyClient.fetch_post_comments(post_id=post_urn, max_items=50, scrape_replies=True)` and locate the comment by `comment_id`. Otherwise ask the user to paste the relevant slice of the thread. Figure out whether the target is: - a top-level comment (parentComment = this comment's URN when replying) - a reply to a top-level comment (parentComment = the TOP comment's URN, not this r...
