Skills are available for users on free, Pro, Max, Team, and Enterprise plans. This feature requires code execution to be enabled. Skills are also available in beta for Claude Code users and for all API users using the code execution tool.
Skills extend Claude's capabilities by giving it access to specialized knowledge and workflows. This guide shows you how to enable, discover, and use Skills in Claude.
Prerequisites
For Enterprise plans: Owners must first enable both Code execution and file creation in Organization settings > Capabilities and Skills in Organization settings > Skills. Owners can also upload skills to provision them organization-wide — these skills automatically appear for all users. Once Skills are enabled at the organization level, individual members can toggle on example skills, access provisioned skills, and upload their own personal skills in Customize > Skills.
For Team plans: This feature is enabled by default at the organization level. Once enabled, individual members can toggle on example skills and upload their own in Customize > Skills.
For Max, Pro, and free plans: You can enable example skills and upload your own in Customize > Skills.
How to enable Skills
Navigate to Settings > Capabilities and ensure that Code execution and file creation is enabled.
Go to Customize > Skills.
Toggle individual skills on or off as needed.
Provision skills organization-wide
Owners of Team and Enterprise organizations can provision skills for all users. These skills appear in your individual Skills list with a team indicator — you can toggle them on or off based on your preferences. For information on provisioning skills for your organization, see Provision and manage Skills for your organization.
Use Anthropic Skills
Anthropic provides several built-in skills that are available to all users, including:
Enhanced Excel spreadsheet creation and manipulation
Professional Word document creation
PowerPoint presentation generation
PDF creation and processing
With Code execution and file creation on, Claude will automatically use these tools when relevant. You don't need to explicitly invoke them—Claude determines when each skill is needed based on your request.
For example, if you ask Claude to "Create a PowerPoint presentation about Q3 results," Claude will automatically use the PowerPoint skill if the capability is enabled.
Add and use custom skills
You can also create and upload your own skills to teach Claude your specific workflows:
Create a skill following the skill structure (see How to create custom Skills for detailed instructions).
Package your skill folder as a ZIP file.
Navigate to Customize > Skills.
To add custom skills, click the "+" button, then select "Upload a skill":
Upload a ZIP file containing your skill folder.
Your skill will appear in your Skills list and can be toggled on or off.
Note: Custom skills you upload are private to your individual account. If you’re on a Team or Enterprise plan and want to share skills with your organization, see Provision skills for your organization.
How Claude uses Skills
Claude automatically identifies and loads relevant skills based on your task. Refer to What are Skills? to learn how this works.
Discover skills from the Skills Directory
The Skills Directory features professionally-built skills from leading platforms like Notion, Figma, and Atlassian. These partner skills are designed to work with their respective MCP connectors, enabling powerful workflows that combine Claude's capabilities with your existing tools.
To install a skill from the Skills Directory:
Visit the Skills Directory at claude.com/connectors.
Browse available skills or filter by category.
Click on a skill to view its details and download link.
Download the skill package from the linked repository (typically GitHub).
Upload the downloaded ZIP file in Customize > Skills.
Manage your Skills
View your Skills
All your skills are listed in Customize > Skills. You can see:
Anthropic skills (created, tested, and maintained by Anthropic)
Custom skills you've uploaded
When each skill was enabled or uploaded
A brief description of what each skill does
Enable/disable your Skills
Toggle any skill on or off using the switch next to it. Disabled skills won't be available to Claude.
Delete custom Skills
To remove a custom skill you've uploaded:
Navigate to Customize > Skills.
Find the skill in your Skills list and click on it to view the details.
Use the toggle in the upper right corner to disable the skill.
To delete the custom skill entirely, click the "..." button next to the toggle, then select "Delete":
Click "Delete" in the confirmation prompt.
If you change your mind, you can add the skill again by re-uploading the file.
Privacy and security details
For Team and Enterprise plans, organization Owners can provision skills for all users through organization settings. Individual peer-to-peer skill sharing is not currently available — users cannot directly share skills with specific colleagues. For personal skills, each individual must upload them to their own account. Skills in Claude and the API operate in Claude's secure sandboxed environment with no data persistence between sessions.
Note that skills may include, or instruct Claude to install, third-party packages and software for Claude to use when completing a task. See here for details on Claude’s container environment and here for API’s container environment.
What are the primary risks of using Skills?
The most significant risks are prompt injection, which allows Claude to be manipulated to execute unintended actions, and data exfiltration, caused by malicious package code or prompt-injected data leaks. We’ve implemented several mitigations to these risks. Refer to our security considerations for code execution for more information.
Important: Only install skills only from trusted sources.
When installing a skill from a less-trusted source, thoroughly audit it before use. Start by reading the contents of the files bundled in the skill to understand what it does, paying particular attention to code dependencies and bundled resources like images or scripts. Similarly, pay attention to instructions or code within the skill that instruct Claude to connect to potentially untrusted external network sources.
Troubleshooting
Skills section not visible
Ensure code execution is enabled in Settings > Capabilities. Then navigate to Customize > Skills to access your skills. Skills require the code execution environment to function.
Claude isn’t using a Skill
Verify the Skill is toggled on in Customize > Skills.
Check that the Skill's description field clearly explains when it should be used.
Ensure the Skill's instructions are clear and well-structured.
Try being more explicit in your request (e.g., "Use my brand guidelines skill to create a presentation").
Upload errors
Common reasons for upload failures:
ZIP file exceeds size limits
Skill folder name doesn't match the skill name
Missing required Skill.md file
Invalid characters in skill name or description
Skills greyed out
If Skills appear greyed out, code execution may be disabled at the organization level (for Team and Enterprise plans) or individually. Check with your organization's Owner or make sure to enable code execution in Settings > Capabilities.
Best practices
Start simple
Begin with Anthropic's pre-built Skills to understand how they work before creating custom skills.
Be specific
Write clear descriptions when writing custom skills. A specific description tells Claude when to invoke your skill.
Test your skills
After uploading a custom skill, test it with a few different prompts to ensure it works as expected.
Organize by purpose
Create separate skills for different purposes rather than a single skill that’s meant to do everything.
