Skills are folders of instructions, scripts, and resources that Claude loads dynamically to improve performance on specialized tasks. Skills teach Claude how to complete specific tasks in a repeatable way, whether that's creating documents with your company's brand guidelines, analyzing data using your organization's specific workflows, or automating personal tasks.
Skills are available as a feature preview for users on Pro, Max, Team, and Enterprise plans. This feature preview 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.
How do Skills work?
Skills improve Claude’s consistency, speed, and performance on many tasks. Skills work through progressive disclosure—Claude determines which Skills are relevant and loads the information it needs to complete that task, helping to prevent context window overload.
When you ask Claude to complete a task, it reviews available Skills, loads relevant ones, and applies their instructions.
Types of Skills
Anthropic Skills
These are Skills created and maintained by Anthropic, such as enhanced document creation for Excel, Word, PowerPoint, and PDF files. Anthropic Skills are available to all users and Claude invokes them automatically when relevant.
Custom Skills
These are Skills you or your organization create for specialized workflows and domain-specific tasks. Here are some potential workflows you could enable using custom Skills:
Apply brand style guidelines to documents and presentations.
Generate communications following company email templates.
Structure meeting notes with company-specific formats.
Create tasks in company tools (JIRA, Asana, Linear) following team conventions.
Execute company-specific data analysis workflows.
Automate personal workflows and customize Claude to match your work style.
Key Benefits
Improvement in Claude’s performance of specific tasks: Skills provide specialized capabilities for tasks like document creation, data analysis, and domain-specific work that requires supplementing Claude's general knowledge.
Organizational knowledge capture: Package your company's workflows, best practices, and institutional knowledge for Claude to use consistently across your team.
Easy customization: Anyone can create Skills by writing instructions in Markdown—no coding required for simple Skills, though you can attach executable scripts to custom Skills for more advanced functionality.
Comparing Skills to other Claude capabilities
Skills vs. Projects
Projects provide static background knowledge that's always loaded when you start chats within them. Skills provide specialized procedures that activate dynamically when needed and work everywhere across Claude.
Skills vs. MCP (Model Context Protocol)
MCP connects Claude to external services and data sources. Skills provide procedural knowledge—instructions for how to complete specific tasks or workflows. You can use both together: MCP connections give Claude access to tools, while Skills teach Claude how to use those tools effectively.
Skills vs. Custom Instructions
Custom instructions apply broadly to all your conversations. Skills are task-specific and only load when relevant, making them better for specialized workflows.
