What it does

Write social media posts for X (Twitter) and LinkedIn that avoid AI tells, pass platform algorithms, and drive engagement. Use when drafting posts, threads, or content for X or LinkedIn.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

8## Why You Need This
9
10You are an LLM. People can tell. The average person scrolling X or LinkedIn in 2025+ has developed a finely tuned radar for AI-generated content. On LinkedIn, over 54% of long-form posts are now AI-generated — and those posts get 45% less engagement than human-written ones. LinkedIn's algorithm actively detects and suppresses obvious AI content, reducing reach by up to 30%. On X, the problem is different but equally fatal: AI posts are bland in an environment that rewards sharp, opinionated, personality-driven writing. Your defaults will get you scrolled past on both platforms.
11
12This guide exists because the way you naturally write — balanced, comprehensive, eager to cover all angles — produces posts that die in the feed. Social posting rewards the opposite: incomplete thoughts that provoke completion, strong positions that provoke disagreement, and raw specificity that provokes recognition.

14**Your goal is not to write a good post. Your goal is to write something that makes people stop scrolling.**

22## How X Works (What You Must Understand)
23
24X's algorithm ranks content on three pillars: relevance, recency, and engagement velocity. That last one matters most for you. A post that gets 50 replies in 10 minutes will massively outperform one that gets 500 likes over 24 hours. The algorithm makes its decision about your post in the first 60 minutes. If it doesn't catch fire early, it's dead.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

050k100k150k200k context window

7.6k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

1 file, 30.5 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md30.5 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 1 file you can review in full before installing. The GPL-3.0 licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/llm-social-posting-guide-x-twitter-linkedin/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/captaincrouton89-llm-social-posting-guide-x-twitt/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/llm-social-posting-guide-x-twitter-linkedin" ] && { [ ! -e ~/.claude/skills/llm-social-posting-guide-x-twitter-linkedin ] || { mv ~/.claude/skills/llm-social-posting-guide-x-twitter-linkedin "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/llm-social-posting-guide-x-twitter-linkedin" ~/.claude/skills/ && echo "Installed ~/.claude/skills/llm-social-posting-guide-x-twitter-linkedin" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/llm-social-posting-guide-x-twitter-linkedin/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as LLM Social Posting Guide in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, llm-social-posting-guide-x-twitter-linkedin.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
