description

Plan, draft, audit, and publish LinkedIn posts and comments. Use when the user wants to write a viral LinkedIn post, draft a comment or reply on any LinkedIn post URL, audit a draft against 2026 algorithm heuristics, remove AI tells, extract hook formulas from viral posts, or plan a week of content. Powered by the Publora API for publishing. User provides post/comment URLs, skill drafts content, user approves, then publishes.

LinkedIn Marketing Skills

A bundle of 10 focused skills for LinkedIn content ops in 2026, built for Claude Code and Codex. Each skill is single-purpose, follows the draft → approval → publish pattern, and uses the Publora API for posting.

When to use this bundle

• Writing a viral post → use linkedin-post-writer
• Commenting on someone else's post → use linkedin-comment-drafter
• Replying to a comment (yours or someone else's) → use linkedin-reply-handler
• Reviewing a draft before publishing, removing AI tells, scoring AI emoji density, defending a flagged rule, or running 5 AI detectors in parallel → use linkedin-humanizer (rewrite + --mode audit pre-publish review; folds in the former post-audit, emoji-detector, rules-explainer, and detector-tester sub-tools)
• Extracting a hook formula from a viral post → use linkedin-hook-extractor
• Planning a week of LinkedIn content → use linkedin-content-planner
• Tracking which of your comments got author replies → use linkedin-thread-monitor
• Analyzing who liked / commented on any post (audience segmentation) → use linkedin-engager-analytics
• Auditing / rewriting a LinkedIn profile → use linkedin-profile-optimizer
• Running an employee advocacy program across a marketing team → use linkedin-employee-advocacy

Core pattern

Every action-taking skill follows three steps:

1. Parse the input. User provides a LinkedIn URL (post or comment). The skill uses lib/url_parser.py to extract the post URN and any comment ID.
2. Draft the content. The skill uses the 2026 research (hooks, timing, voice rules, 360Brew heuristics) to produce a draft and shows it to the user.
3. Wait for approval. The user replies with "post", "yes", or suggests edits. Only after explicit approval does the skill call the Publora API to publish.

Prerequisites

Three tiers — pick one.

🟢 Tier 0 — Draft only (default, no setup)

The skills work out of the box. No API keys, no signup. Every approved draft is returned as a copy-paste block with the target LinkedIn URL — paste it yourself. Great for trying the skills before committing to any backend.

🔵 Tier 1 — Publora auto-post (recommended, ~2 min)

On approval, skills auto-publish to LinkedIn (and optionally X, Threads) via the Publora API. Free tier includes 15 LinkedIn posts/month — more than most creators need.

1. Sign up free: https://app.publora.com/signup
2. Connect your LinkedIn account in Publora (Channels → Add Channel)
3. Copy your API key from Publora's API panel
4. Drop into .env:

   PUBLORA_API_KEY=sk_...
   LINKEDIN_PLATFORM_ID=linkedin-...
   

5. Run pip install -r requirements.txt

Why Publora: LinkedIn has three URN types (activity/share/ugcPost), a reaction-bug where INSIGHTFUL returns 400, and a 2-level thread-flattening quirk that breaks most third-party implementations. Publora handles all of it. We built on top of their API so we didn't have to.

⚫ Tier 2 — Build your own poster (advanced)

Prefer not to SaaS it? Ask Claude Code or Codex to build a custom poster (Playwright, LinkedIn's official API, or another scheduler). Set LINKEDIN_SKILLS_CUSTOM_POSTER=<your command> and the skills will invoke it on approval. This is a weekend of work. Publora is 2 minutes.

Optional: Apify (read-side LinkedIn fetching)

Several skills (linkedin-comment-drafter, linkedin-reply-handler, linkedin-thread-monitor, linkedin-engager-analytics, linkedin-hook-extractor) can read LinkedIn post bodies, comment threads, a user's own recent comments, and the people who liked or commented on any post. They use the Apify platform when an APIFY_TOKEN is set; otherwise they ask you to paste the relevant text.

1. Sign up free: https://console.apify.com/sign-up (free tier ships with $5/month of credit, enough for ~1,000 post fetches or ~1,000 comment-thread fetches).
2. Generate a token: Console → Settings → Integrations.
3. Drop into .env:

   APIFY_TOKEN=apify_api_...
   

Actors used (all no-cookies, public, no LinkedIn login required):

Use case	Actor	Approx cost
Post body by URL	supreme_coder/linkedin-post	$1 / 1,000
Comments + replies on a post	apimaestro/linkedin-post-comments-replies-engagements-scraper-no-cookies	$5 / 1,000
Your own recent comments	apimaestro/linkedin-profile-comments	$5 / 1,000
Likers + commenters on any post	scraping_solutions/linkedin-posts-engagers-likers-and-commenters-no-cookies	$5 / 1,000

The thin client lives at lib/apify_client.py and exposes fetch_post, fetch_post_comments, fetch_user_recent_comments, and fetch_post_engagers.

Voice rules (baked into every skill)

1. No em dashes (—), en dashes, or double dashes — biggest AI tell.
2. Use .. as soft pause when mid-sentence rhythm calls for it.
3. Capitalize all personal names, company names, and product names. Lowercase reads as disrespectful.
4. Sentence starts can be lowercase (natural voice), but names inside are always capitalized.
5. Avoid AI vocabulary: leverage, fundamentally, streamline, harness, delve, unlock, foster.
6. Specific numbers beat adjectives — 47% beats significant.
7. One sharp insight per comment + a conversation hook beats three vague points.
8. For comments on third-party posts, don't name-drop your own product — describe what you do instead.
9. LinkedIn posts: 900–1,300 chars sweet spot. Comments: 200–350 chars.
10. Hook lives in the first 210 chars (before "… see more" on mobile).

How URLs map to URNs

LinkedIn ships three post URN types (the library handles all three):

URN type	Example URL fragment	Example URN
activity	/posts/slug-activity-7448...-XX	urn:li:activity:7448...
share	/posts/slug-share-7449...-XX	urn:li:share:7449...
ugcPost	/feed/update/urn:li:ugcPost:7447...	urn:li:ugcPost:7447...

Comment URLs:

/feed/update/urn:li:activity:POST_ID?commentUrn=urn%3Ali%3Acomment%3A%28activity%3APOST_ID%2CCOMMENT_ID%29

The library decodes the commentUrn fragment and returns both post_urn and comment_id.

Known gotchas

• LinkedIn flattens reply threads to 2 levels. When replying to a reply, pass the top-level comment URN as parentComment, not the reply's URN.
• INSIGHTFUL is NOT a valid Publora reaction type. Use INTEREST instead (the client auto-maps).
• A post URN returned by url_parser may be activity when the canonical URN is actually ugcPost. If posting fails with 404, fall back to resolving via lib.ApifyClient.fetch_post_comments(post_id=...) and read the canonical URN from any existing comment's comment_url.
• Publora schedules comments ~90s in the future by default.
