32 Free Marketing Skills for Claude Code and AI Agents

Real, working SKILL.md files for marketers — the open Claude Agent Skills format. Read any one, copy it into your .claude/skills/ folder, and your agent gains the skill.

32 files 20 Letaido originals 12 Ahrefs pipeline 100% first-party

This is a free, growing library of 32 real SKILL.md files for marketers — the same portable format Claude, Claude Code, Cursor, and Codex all read. Every one is copyable and downloadable below; drop it into your agent and it picks up the skill. They're organized by the marketing job they do. Every file here is first-party — written by us, no third-party licensing to worry about — and comes from one of two places:

  • Letaido originals (20) — written by us and released CC0. Use, modify, and ship them freely, no attribution required.
  • Ahrefs blog pipeline (12) — the actual skills behind the Ahrefs blog, from keyword research to a publish-ready draft.

One note: skill files instruct an agent how to act. These are plain markdown with no hidden scripts — read any one right here before you run it, the way you'd treat any code you didn't write.

What are skill files?

A skill is a folder with a SKILL.md file that teaches an AI agent how to do one job well. Save one into .claude/skills/<name>/SKILL.md (or upload it in the Claude app) and the agent loads it automatically when your task matches — no prompt engineering each time. It works with any tool that reads the open Agent Skills spec: Claude, Claude Code, Cursor, Codex, and more. Treat the files here as starting points and adapt them to your own product and voice.

The format is deliberately simple: a few lines of YAML frontmatter (a name and a description that tells the agent when to reach for it), then plain-language instructions in Markdown. Here's a stripped-down example:

---
name: ai-content-humanizer
description: Use when a draft reads like AI wrote it and you
  want it to sound human before publishing. Triggers on
  "humanize this" or "remove the AI tells."

# AI Content Humanizer

You are an editor whose only job is to make writing sound
like a real person wrote it. Don't change the facts or the
argument — change how it *reads*.

## Rules
- Cut hedging and filler ("in order to", "it's worth noting").
- Vary sentence length. Short punches next to longer lines.
- Kill the "not only X but also Y" cadence.
- Read it aloud — if you'd never say it, rewrite it.
That's a real one, trimmed — the full ai-content-humanizer skill is in the list below.
