Claude Skills

Introducing Agent Skills (Claude Skills): Claude can now use Skills to improve how it performs specific tasks. Skills are folders that include instructions, scripts, and resources that Claude can load when needed. Claude will only access a skill when it's relevant to the task at hand. When used, skills make Claude better at specialized tasks like working with Excel or following your organization's brand guidelines. https://claude.com/blog/skills

• Skills extend Claude Code with your team's expertise and workflows. Install skills via plugins from the anthropics/skills marketplace. Claude loads them automatically when relevant. Share skills through version control with your team. You can also manually install skills by adding them to ~/.claude/skills. The Claude Agent SDK provides the same Agent Skills support for building custom agents.

Skills are:

• Composable: Skills stack together. Claude automatically identifies which skills are needed and coordinates their use.
• Portable: Skills use the same format everywhere. Build once, use across Claude apps, Claude Code, and API.
• Efficient: Only loads what's needed, when it's needed.
• Powerful: Skills can include executable code for tasks where traditional programming is more reliable than token generation.
