Guide

Install a skill in Claude.

Two minutes, no code to write. A skill is a folder containing a SKILL.md file: Claude reads it and applies its method when your request matches.

What’s in the zip.

Each pack downloads as a single zip file, for example clients-pack.zip. Once unzipped:

clients-pack/
README.txt            the steps, in short
outreach-message/     one folder per skill, for Claude Code
  SKILL.md
follow-ups/
  SKILL.md
…
zips-claude-ai/       one zip per skill, for claude.ai
  outreach-message.zip
  follow-ups.zip
  …

claude.ai

On claude.ai.

In the browser, or in the app signed in to the same account. You need a Claude plan that supports skills.

  1. Unzip the pack. Inside you’ll find the zips-claude-ai folder, with one zip per skill.
  2. Open the skills settings on claude.ai:
    Settings › Capabilities › Skills

    Skills need code execution: if it’s turned off, turn it on from the same page.

  3. Upload the zips one by one from zips-claude-ai. One zip = one skill. Don’t upload the whole pack’s zip.
  4. Check that they’re turned on, then start a new conversation.
Team or Enterprise plan? An admin in your organization may need to allow skills before the option appears.

Claude Code

In Claude Code.

Claude Code reads skills from a folder on your computer. To use them in all your projects, put them in your home folder:

  1. The skills folder is:
    ~/.claude/skills/
  2. Copy each skill folder into it (the one containing SKILL.md). In a terminal, from the folder where you downloaded the zip:
    Terminal
    mkdir -p ~/.claude/skills
unzip clients-pack.zip -d clients-pack
for d in clients-pack/*/; do
  [ -f "$d/SKILL.md" ] && cp -R "${d%/}" ~/.claude/skills/
done

    Replace clients-pack with the name of your pack. You can also copy the folders by hand: on a Mac, Cmd + Shift + . shows hidden folders.

  3. Start a new Claude Code session: skills are loaded at startup.
A skill for a single project? Put its folder in .claude/skills/ at the root of the project instead of your home folder.

Using

Then just ask.

There’s no command to remember. Each skill has a description that says when it applies: when your request matches, Claude uses it on its own and tells you.

I have an interview on Thursday, here’s the job posting and my resume.
✓Skill used: interview-prep

To check the installation

Ask Claude: “Which skills do you have available?” It should list the ones you just installed.

To pick the skill yourself

Name it in your request: “Use the follow-ups skill for this client.”

Troubleshooting

If it doesn’t work.

  • The skill doesn’t show up in Claude Code

    Check that the SKILL.md file sits directly in the skill’s folder (~/.claude/skills/follow-ups/SKILL.md), with no extra folder in between. Don’t rename the folder: its name must stay the skill’s name. Then start a new session.

  • claude.ai rejects the file

    Upload a zip from the zips-claude-ai folder, one skill at a time. The whole pack’s zip contains several skills and isn’t accepted as is.

  • The Skills option is nowhere to be found

    Your plan may not support skills, or your organization has turned them off. Also check that code execution is turned on.

  • The skill doesn’t trigger

    Phrase your request as a concrete situation (“They haven’t replied in eight days”), or name the skill. On claude.ai, check that it’s turned on in the settings.

Questions

Frequently asked questions.

Can I install them on claude.ai and in Claude Code?

Yes. The two installations are independent: follow both procedures, with the same pack.

How do I update a pack?

Download it again from your download page, which always gives the latest version. Replace the folders in Claude Code, or re-upload the zips on claude.ai.

Can I edit a skill?

Yes: open its SKILL.md in a text editor and change the tone, the steps or the rules. Keep the “name” line identical to the folder name. For claude.ai, zip the folder again and re-upload it.

How do I uninstall a skill?

On claude.ai, turn it off or delete it in Settings › Capabilities. In Claude Code, delete its folder in ~/.claude/skills/.

Does it work on the free plan?

Skills require a Claude plan that supports them. Check Anthropic’s current terms, they may change.
