Linkedin Thread Monitor

LinkedIn Thread Monitor

Track which of your comments earned author replies. The author-reply signal is the highest-value inbound LinkedIn produces; this skill ensures you respond inside the window where momentum compounds.

Depends on APIFY_TOKEN. Without it, falls back to user-paste of recent comment URLs.

When to use

• Daily: "What threads need follow-up today?"
• After posting a batch of comments: "Check back in 6 hours"
• When an author replied personally: "Draft the response"

Input

• Your LinkedIn handle (last path segment of profile URL, e.g. your-handle)
• Optional: window in hours (default 72)

Output

Output format (daily report, warm-thread preview, weekly roll-up): see references/output-spec.md. Headline: a table of recent comments with author-reply status + recommended action.

Steps

1. Fetch user's recent comments. If APIFY_TOKEN is set, call lib.ApifyClient.fetch_user_recent_comments(username=<your-handle>, result_limit=30). Each item already includes the parent post body, post URL, post author, and reaction stats. If APIFY_TOKEN is not set, ask the user to list (or paste) the URLs of comments they've posted in the last 72h.
2. For each comment posted in last 72h: check the parent post's comment tree (use fetch_post_comments(post_id=..., scrape_replies=True)) for:
   • Replies to the user's comment
   • Whether the author posted any of those replies
   • Timestamps (time since user's comment, time since latest reply)
3. Classify stage:
   • Hot (<6h): author just replied. Respond within 90 min for max thread momentum
   • Warm (6-24h): the warm-reply window. Author replies most happen here
   • Cool (24-72h): still respondable but lower velocity
   • Dormant (>72h): don't reply in thread. Consider DM
4. Draft responses for warm threads using linkedin-reply-handler.
5. Flag suspicious patterns:
   • Author replied but also deleted someone else's comment (author is actively moderating, tread carefully)
   • Commenter is in thread self-promoting (your reply shouldn't engage them)
6. DM routing: if thread is dormant but the author engaged meaningfully, draft a DM that references the thread specifically.

Warm-reply window

Anchored to a 2026-04 data point: a CEO replied to Serge's comment 22h after the original post. Reply-rate distribution: 0-6h 70%, 6-24h 25% (higher quality), >24h rare. Follow-up timing: 0-6h reply respond within 90 min; 6-24h within 2h; >24h within 4h before it goes cold. See references/thread-timing.md for the full matrix.

Inbound-quality signals

High-quality = follow up: founder/operator title, company in ICP, active posting history, >10 mutual 2nd-degree connections, prior thoughtful comments on user's posts.

Low-quality = skip: generic praise, template language ("I'd love to hop on a quick call"), sales/agency profile with no operator history, same comment copy-pasted across many creators.

Hard rules

Global voice rules: see root SKILL.md §Voice rules. Additional skill-specific rules:

• Never reply to a reply later than 72h after the thread's last turn. Switch to DM.
• Never chain 3+ replies under one comment (thread spam).
• If the author deleted their reply, do not reply. They reconsidered.
• Don't DM a warm thread before first replying publicly (skips a step).

Cost accounting

A typical creator running this skill 5 days/week stays well under the $5 free monthly credit.
