Creating Skills & Commands

This skill teaches how to create effective Claude Code skills following the official specification from code.claude.com/docs/en/skills.

Commands and Skills Are Now The Same Thing

Custom slash commands have been merged into skills. A file at .claude/commands/review.md and a skill at .claude/skills/review/SKILL.md both create /review and work the same way. Existing .claude/commands/ files keep working. Skills add optional features: a directory for supporting files, frontmatter to control invocation, and automatic context loading.

If a skill and a command share the same name, the skill takes precedence.

When To Create What

Use a command file (commands/name.md) when:

• Simple, single-file workflow
• No supporting files needed
• Task-oriented action (deploy, commit, triage)
