How to install a skill in Claude

Steps checked: November 2026. Claude's menus change often. If yours look different, search Claude's help center for "Use skills in Claude".

It takes about two minutes. You need a Claude account, and the free plan works. Do it on a computer the first time.

1. Go to claude.ai and sign in.
2. Open Settings, then Capabilities, and check that Code execution and file creation is switched on. In some versions it's called Create and edit files. Skills need it.
3. In the left sidebar, open Customize, then Skills.
4. Click the + button, choose Create skill, then Upload a skill.
5. Choose one skill file from the install-in-claude folder we sent you, for example bill-decoder.zip. Upload it exactly as it is. Don't unzip it.
6. The skill appears in your list, switched on. Repeat steps 4 and 5 for each skill you want.
7. Start a new chat and ask for what you need. Claude uses the skill by itself when your request matches it.

Using ChatGPT, Gemini or Copilot

Open the paste-in-versions folder. Each skill has a text file. Copy everything in it, paste it into your AI chat as the first message, then send your bill, your document or your question. It's the same process. You just paste it at the start of each new chat.

If something goes wrong

• The upload is refused. Make sure you chose one of the small skill files inside the install-in-claude folder (such as bill-decoder.zip), not the big download they all arrived in, and that you didn't unzip it first.
• There's no Skills option. Check step 2 again. If you use Claude through work, your administrator decides whether skills are allowed.
• Claude isn't using the skill. Check it's switched on under Customize, then Skills. Start a new chat, and say plainly what you want, for example "explain this bill". You can also name it: "use the bill decoder skill".
• You're on your phone. Install from a computer. It's easier to handle the files there.

Switching a skill off

Go to Customize, then Skills. Each skill has its own switch. Turning one off changes nothing else in your account.

Reading a skill before you install it

Every Killer AI skill is plain written instructions with no code inside. To check, unzip a copy and open the file called SKILL.md in any text editor, such as Notepad or TextEdit. Every word Claude will follow is there.
