We just launched the Claude Skills Hub — a free library of 40+ ready-to-use skills that turn Claude into a GTM engineering assistant.

Each skill is a .md file you download and load into Claude. No code, no terminal commands, no npx — just a file that gives Claude deep expertise on a specific GTM task.

Here's how it works, step by step.

Claude skills are structured Markdown files (.md) that contain detailed instructions, context, and best practices for a specific task.

When you load a skill into a Claude conversation, it's like handing an expert playbook to your AI. Claude reads the instructions and follows them precisely — producing higher-quality, more consistent outputs than a generic prompt ever could.

Think of it this way: a prompt says "write me a cold email." A skill says "here's our proven framework for cold emails, with persona research steps, subject line formulas, CTA patterns, and follow-up logic — now write me a cold email using all of this."

Head to lemlist.com/claude-skills to see the full library.

Skills are organized by category — lead research, email copywriting, data enrichment, campaign analysis, ICP building, and more. Each card shows the skill name, a short description, and which tools it pairs with.

Pick the skill that matches what you're trying to accomplish and click the download button to grab the .md file.

Go to claude.ai or open the Claude desktop app. Start a fresh conversation.

You can use the free plan or any paid plan — skills work with all Claude versions. That said, Claude Pro or Team will give you longer context windows, which means better performance with complex skills.

This is the key step. Attach the downloaded SKILL.md file to your message — just like you'd attach any document.

On claude.ai: Click the paperclip icon (📎) in the message bar, select your .md file, and hit send.

On Claude Desktop: Drag and drop the file directly into the chat window, or use the attach button.

Along with the file, send a message like:

Claude reads the entire .md file, understands the framework, and applies it to your request.

Most skills will ask Claude to request specific information from you — your ICP, your product, your campaign goals, or your existing data.

The more context you provide, the better the output. For example, if you're using a lead scoring skill, share your existing lead list (CSV or pasted data), your ICP criteria, and what signals matter most to your team.

You can also attach additional files alongside the skill — spreadsheets, campaign exports, competitor research — anything Claude can read and use.

Once Claude produces its first output, you can refine it within the same conversation. The skill stays loaded — so every follow-up message benefits from the same framework.

Ask Claude to adjust the tone, add more personalization, change the angle, or process a different set of leads. The skill acts as a persistent set of instructions throughout the entire conversation.

Here's a concrete walkthrough:

The skill handles the copywriting framework. You just bring the context.

If you use Claude Pro or Team, you can add skill files to a Claude Project. This means the skill is always loaded — you don't need to re-upload it every time you start a new conversation.

To do this:

This is the most efficient setup if you use multiple skills regularly.

The library covers the full GTM workflow. Here are some examples of what you'll find:

New skills are added regularly. Check the Skills Hub for the latest additions.

A prompt is a one-shot instruction. A skill is a complete methodology.

Prompts work for simple requests. But for complex GTM tasks — like building a multi-step sequence, scoring a lead list, or analyzing a campaign — you need structure. Skills provide that structure in a reusable, shareable format.

The result is more consistent output, fewer back-and-forth corrections, and a workflow you can repeat across your entire team.

Important clarification: these skills are .md files you upload to a Claude conversation. They are not Claude Code skills that require npx, a terminal, or any developer setup.

If you can attach a file to a chat message, you can use these skills. That's it. No installation, no dependencies, no command line.

The entire skills library is free and open source.
