9. How to Install Claude Skills in 3 Steps

Choose the tool you are using below: Claude.ai / Claude Desktop (Cowork) and Claude Code have different installation processes:

Method 1: For Claude.ai and Claude Desktop (Cowork)

For general users, all operations are completely performed using the mouse and the web interface:

1. Step 1: Enable code execution: Log in to claude.ai, click on your profile picture in the bottom left corner, select Settings, navigate to the Capabilities tab, and toggle on “Code execution and file creation”. (This is a mandatory requirement for the Skills section to appear).
2. Step 2: Open the Skills management interface: Click on your profile picture again, select Customize, and go to the Skills section in the sidebar. Click the “+” button, select “+ Create skill”, and choose “Upload a skill”.
3. Step 3: Upload the .zip file and activate: Select the .zip file of the skill you want to install (keep the zip file intact, no need to unzip). Once uploaded, toggle the switch next to the skill to the On state.

Method 2: For developers using Claude Code CLI

For developers who want to manage skills directly via source code files:

1. Step 1: Extract into the skills directory: Download the .zip file to your machine and extract it into the global configuration directory:
   Extract SkillCopy

   unzip ten-skill.zip -d ~/.claude/skills/

2. Step 2: Verify the standard directory structure: Ensure that the SKILL.md file is located directly inside the skill’s subdirectory:
   Standard StructureCopy

   ~/.claude/skills/ten-skill/SKILL.md

3. Step 3: Open Claude Code and verify the list: Start a new session and enter the following command to view the list of recognized skills:
   Check SkillCopy

   /skills

10. Common Errors and Troubleshooting

A summary of solutions for common issues encountered during the installation and operation of Claude Skills:

Cannot find the Skills section in Settings / Customize
▼

Cause: You have not enabled the code execution feature.
Solution: Go to claude.ai/settings/capabilities and toggle on ‘Code execution and file creation’. If using an organizational account (Team/Enterprise), contact your organization Admin to grant this permission from the admin console.

Skill toggle is enabled, but Claude does not automatically use the skill
▼

Solution: Claude decides to trigger a skill based on matching the description in the SKILL.md file with your prompt. If Claude does not automatically detect it, call the skill directly by name in your prompt (for example: ‘Use the docx skill to generate a document based on the template…’).

Failed to upload .zip file to Claude Cowork
▼

Solution: Check if the .zip file exceeds the size limit, whether the folder name contains special characters, or if the archive is nested within multiple subfolder levels. The root directory inside the zip file must contain the SKILL.md file directly.

Claude Code CLI does not recognize the newly extracted skill
▼

Solution: Check the folder path: the skill must be located at ~/.claude/skills/skill-name/ (shared across all projects) or .claude/skills/skill-name/ (specific to the current project only). Run /skills to verify again.

Is it safe to install skills from external sources?
▼

Security Note: You should only install skill packages from trusted sources. Before installing, it is recommended to preview the SKILL.md file and accompanying scripts to ensure there is no malicious code or unfamiliar network access requests.

11. Frequently Asked Questions (FAQ)

Answering common questions about features and privacy when using the Claude Skills ecosystem:

Can Claude Skills be used on a free Claude account?
▼

Yes. You can use basic skills even on a free account, as long as you have enabled ‘Code execution and file creation’ in the Settings Capabilities section.

Do skills installed on Claude.ai automatically sync to Claude Code?
▼

No, they do not sync automatically. Claude.ai runs in Anthropic’s cloud environment, while Claude Code runs directly on your local machine. If you want to use them in both places, you need to upload them to the web and copy them to the ~/.claude/skills/ directory on your machine.

Can I create my own set of Skills?
▼

Absolutely. Each skill is simply a folder containing a SKILL.md file that specifies instructions, rules, and supporting scripts. You can write your own following Anthropic’s standard template.

Can I share Skills with members of my company?
▼

If your company uses Claude Team or Enterprise plans, the organization owner (Admin) can enable shared access so all members can use a standardized set of Skills.
