Skills are named, reusable agentic workflows that you can trigger by name. They’re like macros for Claude — encapsulating multi-step processes so you can run them repeatedly without re-describing the steps.

​
What skills are

A skill is a prompt or workflow definition that Claude executes via SkillTool. Skills can:
  • Encode your team’s specific conventions
  • Automate repetitive multi-step tasks
  • Wrap complex instructions into a single invocation

​
Running a skill

> /skills
This lists available skills. Run a skill by name: 
> Run the code-review skill
> Execute the deploy-to-staging skill
> Use the add-tests skill on src/api/users.ts
Or directly invoke a skill in conversation: 
> Run the "generate-changelog" skill for the commits since last tag

​
Managing skills

The /skills command provides a management UI: 
> /skills
Options:
  • List all available skills (built-in and custom)
  • Add a new skill
  • Edit an existing skill
  • Delete a skill

​
Bundled skills

Claude Code ships with built-in skills for common workflows. These are stored in src/skills/bundled/ and cover tasks like code review, documentation generation, and testing patterns.

​
Creating a custom skill

Skills are stored in ~/.claude/skills/. Create a new .md file describing the workflow: 
---
name: add-error-handling
description: Add consistent error handling to a TypeScript function
---

Read the target function. Identify all places where errors could occur (async calls, type assertions, external data). Add try/catch blocks with specific error types. Use the project's existing error handling patterns from src/utils/errors.ts.
Save this as ~/.claude/skills/add-error-handling.md. It’s immediately available: 
> Run the add-error-handling skill on src/api/payments.ts

​
MCP-based skills

Skills can also be loaded from MCP servers via mcpSkillBuilders.ts. This lets teams share skills through a central MCP server.
Good candidates for skills: anything you ask Claude to do more than twice. Consistent code review checklists, project-specific refactoring patterns, and deployment workflows are all good fits.
