efecto-social-media is a skill for Claude Code from The-Utopia-Studio/skills. It costs 83 tokens per session (6,689 once invoked), scanned A, original, Apache-2.0.

A design workflow for creating visual assets for social platforms such as Instagram, YouTube, TikTok, LinkedIn, and Pinterest. It connects the coding agent to the Efecto design canvas through an MCP server, a tool connection for agents.

In plain words
What is it for?
Use it to create social posts, carousels, stories, thumbnails, covers, slides, pins, and other listed social-media graphics.
Why use it?
It gives platform-specific design guidance and a way to send design commands to Efecto. Without the Efecto connection, the described design tools are not available.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

efecto-social-media scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Efecto — Social Media Design Guide

Design social media assets — Instagram, YouTube, TikTok, Twitter/X, LinkedIn, Pinterest, Facebook — using the Efecto design tool. Proper sizing, bold typography, and platform-specific best practices.


Setup

This skill requires the Efecto MCP server. Check if it's available by looking for tools like create_session, add_section, or get_document in your tool list.

If Efecto tools are NOT available, install the MCP server:

Claude Code

claude mcp add efecto -- npx -y @efectoapp/mcp

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "efecto": {
      "command": "npx",
      "args": ["-y", "@efectoapp/mcp"]
    }
  }
}

Windsurf / VS Code / Other MCP Clients

{
  "mcpServers": {
    "efecto": {
      "command": "npx",
      "args": ["-y", "@efectoapp/mcp"]
    }
  }
}

Once installed, you'll have access to 46 design tools plus a standalone image search tool. The MCP server connects your agent to the Efecto design canvas at efecto.app.

How It Works

  1. Your agent creates an Efecto session via MCP (create_session)
  2. You open the returned design URL in your browser
  3. The agent pushes design commands — you see every change live
  4. Iterate with natural language until the design is perfect

Using Efecto Tools — Quick Reference

Session Workflow

Every design starts with a session:

create_session  label: "Instagram Carousel"

Returns { sessionId, designUrl }. Tell the user to open the URL, then poll session_status until browserConnected: true.

Building Social Media Designs

The primary workflow is: create artboard → add sections with JSX → refine with updates.

# 1. Create an artboard (Instagram post example)
create_artboard  name: "Slide 1"  width: 1080  height: 1080  backgroundColor: "#111827"  className: "flex flex-col"

# 2. Add content with JSX
add_section  parentId: "<artboard-id>"  jsx: '<section className="flex flex-col items-center justify-center gap-8 p-16 w-full h-full">
  <h1 className="text-7xl font-extrabold text-white text-center leading-none">Stop designing like it&apos;s 2020</h1>
  <p className="text-xl text-gray-400 font-medium">Swipe for 5 rules -></p>
</section>'

# 3. Duplicate artboard for carousel slides
duplicate_artboard  artboardId: "<artboard-id>"  newName: "Slide 2"

# 4. Read state and batch-update the duplicate
get_document
batch_update  updates: [
  { nodeId: "abc", textContent: "01" },
  { nodeId: "def", textContent: "White space is not wasted space" }
]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
