What it does

Linkedin Posts is an agent skill from kostja94/marketing-skills. When the user wants to create LinkedIn post copy or optimize for LinkedIn. Also use when the user mentions "LinkedIn post," "LinkedIn article," "professional post," "post to LinkedIn," "LinkedIn content," "LinkedIn copy," "B2B LinkedIn," "LinkedIn engagement," "LinkedIn feed," "share box," "document post," "poll," "Newsletter," "reshare," or "LinkedIn marketing." For LinkedIn ads, use linkedin-ads.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Social media posts, Paid advertising and Newsletters. It works with LinkedIn. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.

When your agent uses it

  • Wants to create LinkedIn post copy
  • Optimize for LinkedIn
  • The user mentions LinkedIn post
  • LinkedIn article

Example prompts

  • “LinkedIn post,”
  • “LinkedIn article,”
  • “professional post,”
  • “/linkedin-posts”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. First line (≤210 chars; hook)
  2. Full post with character count
  3. Hashtags (a few, relevant; end of post)
  4. Image specs (if design agent needs dimensions)
  5. Form note if not a plain post (e.g. “pair with a 5-slide document” or “use Article for 1,200+ words”)

What it can do on your machine

Read from SKILL.md and the folder at commit 8dd89c5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • linkedin.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Linkedin Posts loads about 3k tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 1,365 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~104
When it runs · the whole SKILL.md, loaded when a task matches
~3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Platforms: LinkedIn

Guides LinkedIn post copy creation and optimization. Use for generating publish-ready professional content. Suitable for copy agents and design agents (image specs).

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Output: Publish-Ready Copy

This skill enables agents to generate LinkedIn post copy optimized for engagement. Output includes character-counted text and structure for the "See more" threshold.

Post Types and Entry Points (organic)

KindWhat to know
Start a postShort update; can include link preview if you paste a URL. Same feed format as other updates.
PhotoSingle or multiple images (carousel in feed).
VideoUploaded file (distinct from LinkedIn Live, which is live streaming and has separate gating).
Write articleArticle = long-form editor, separate from the short post box; long URL, better for depth and some off-site discoverability.
DocumentPDF / PPT / DOC (slides in feed). Official limits (check current help): on the order of ~100MB / ~300 pages per file—verify when publishing.
PollEngagement driver; keep question and options scannable.
More (menu)Often includes celebrations, hiring-style share, Find an expert, etc. (varies by product/region).
ReshareReshare or quote another member’s post with your take—adds context; avoid empty reshares.
NewsletterSeries subscription; not the same as a one-off post but compound reach over time.
EventCreate/promote events via a dedicated flow, not the same as a plain text post.

Product detail: Get started with posting on LinkedIn · Upload and share documents

Why it matters for copy: Match CTA and length to the form (e.g. a document deck vs a 5-line hot take). Do not treat a short post and an Article as interchangeable.

Platform Positioning

LinkedIn is a professional network—its core value is career identity, B2B relationships, and professional content. Key differences from general social platforms:

DimensionLinkedInMeta / X / TikTok
Primary intentJob seeking, B2B networking, industry learningEntertainment, social, discovery
IdentityReal name + career historyUsername or lifestyle persona
Content toneProfessional, constructiveCasual, entertaining, opinion
B2B lead valueHigh (job title + company targeting)Low to medium
Algorithm signalProfessional interest + network + editorialEngagement, watch time, virality

Prioritize LinkedIn when: targeting B2B buyers, building professional authority, recruiting, or publishing industry thought leadership. For consumer brand awareness or entertainment, other platforms are often more effective.

How the Feed Ranks (what to write for)

  • The feed is not a pure reverse-chronological friend list. It blends 1st-degree connections, follows, company/topic interest, and recommended “out of network” content from the Economic Graph, plus ads. How the Feed ranks content
  • Relevance uses context of the post, profile and network signals, and behavior (read, react, comment, share, dwell). Demographics like age or gender are not used to rank feed visibility (per public help guidance).
  • Platform direction in recent public communications: more LLM/semantic understanding, less inauthentic engagement and engagement-bait / low-quality repetition; favor real expertise and meaningful discussion. Background on feed engineering (blog)

Writing implications: Strong first line and on-topic depth; comments that add substance; avoid templates that look automated or “pod” coordinated.

Off-Site Search Visibility (SEO & GEO)

LinkedIn content is visible to search engines on a selective basis—understand what gets indexed for SEO and cited for GEO.

What Google Indexes vs. What Is Login-Gated
SurfaceSearch VisibilityGEO (AI citation) Value
Public profile (Headline, About, Experience)Indexed for name/company/role queriesStrong entity signal; citable paragraphs
Articles (long-form editor)Indexed when set to publicHigh; structured paragraphs with keywords
Company PageIndexed for brand queriesMedium; brand entity signals
Short feed postsLogin-gated—not indexedLow; cannot be cited if behind login
Newsletter issuesIndexed if public; behind login if subscriber-onlyDepends on visibility setting
SEO Through LinkedIn
  • Headline is the most SEO-visible field on your profile—treat it as a title tag. Include primary keyword + value proposition (e.g. “B2B SaaS Marketing | Helping startups scale through content”).
  • About section: Write public-facing paragraphs with keywords and proof points. This is indexed and often appears in Google search snippets.
  • Featured section: Use to showcase key links (site, case studies, press). These appear on your public profile and add backlink value.
  • Articles: Long-form content on LinkedIn ranks independently on Google. Treat as secondary publication, not primary—repurpose site content with canonical or unique article.
  • Consistency: Align name, headline, and entity names across LinkedIn, your site, and other public bios. See entity-seo for sameAs alignment.
Show full SKILL.md (629 more words)Show less
GEO Through LinkedIn
  • Entity consistency: Your LinkedIn profile is a high-authority entity source. AI search tools (ChatGPT, Perplexity, Google AI Overviews) can cite your LinkedIn profile when answering “who is [person]” or “what does [company] do” queries.
  • Citable paragraphs: Write your About section in answer-first format (40–60 words per block) so AI tools can extract and cite it directly.
  • Evidence links: Add links to your site, case studies, talks, and publications in Featured and About. AI tools cite external links as supporting references.
  • Public articles: Publish LinkedIn Articles on relevant topics; well-structured articles with data and citations increase the likelihood of AI citation.
  • Limitation: Short feed posts behind login walls are invisible to AI crawlers and search engines. Do not rely on feed posts for GEO.

Actionable checklist:

  • Headline includes primary keyword + value proposition (treat as meta title)
  • About section written in answer-first format (quotable paragraphs)
  • Featured section showcases site, case studies, key publications
  • Entity names (name, company, role) consistent across LinkedIn and site
  • At least one public Article published on a relevant industry topic
  • LinkedIn profile URL uses custom alias (not default ID string)

For implementation details: open-graph (link previews), entity-seo (people/org sameAs), generative-engine-optimization (cross-platform GEO).

Profile Modules for Discovery

Key LinkedIn profile modules that affect search visibility and AI citation:

ModuleSEO/GEO ValueOptimization
HeadlineHighest—indexed, appears in search snippetsCustomize beyond job title; include keyword + audience + value
AboutHigh—indexed; citable for AIWrite in answer-first format; include proof points, external links
FeaturedMedium—showcases key links on public profileAdd site URL, case studies, press, portfolio
Experience (media)Low-medium—media attachments are indexedAdd relevant documents, links, images to each role
Skills & EndorsementsLow—indexed but thin signalInclude relevant skills; endorsements add social proof
ArticlesHigh—indexed and rankablePublish long-form content with keywords and data
Custom URLIndirect—clean URL improves shareabilitySet to firstnamelastname or similar
