Create Custom Slash Commands

Custom slash commands (skills) let you create reusable prompts. Create a .claude/skills/ directory and add markdown files:

mkdir -p .claude/skills

Create a commit skill at .claude/skills/commit.md:

---
name: commit
description: Create a conventional commit
---

Review all staged changes with `git diff --cached`.
Write a conventional commit message following this format:

- feat: for new features
- fix: for bug fixes
- refactor: for code refactoring
- test: for adding tests

Keep the first line under 72 characters.
Add a body if the change needs explanation.

Now you can use it:

/commit

Claude will read the skill file and follow those instructions. You can create skills for anything — code review, PR creation, deployment checks, etc.

Skills can also reference other tools and have complex multi-step workflows.
