Sub-Agents and Slash Commands

~60 min

Goal — Round out your picture of the harness with two smaller tools.

By the end — A clear one-line grasp of how skills, sub-agents, workflows, and slash commands differ.

1Defining your own sub-agent

Beyond the ones Claude spawns automatically, you can define a sub-agent with a specific role and instructions, for a job you repeat.

Paste into Claude Code
Briefly explain how I would define my own sub-agent and when it is worth doing.

2Keep it in proportion

Note

Most of the time, the session and its automatic helpers are all you need. Defining your own is for narrow, repeated roles — not everyday work.

3Understand slash commands

A slash command is a shortcut you type as /name to run a saved instruction — a quick way to trigger something you do often.

Paste into Claude Code
Briefly explain slash commands and give an example of a useful one.

4See how the pieces relate

Skills teach moves; sub-agents do delegated work; workflows run many at once; slash commands are quick triggers. Together they are your orchestration toolkit.

Paste into Claude Code
Summarize how skills, sub-agents, workflows, and slash commands differ, in one line each.

Recap — You rounded out the harness — defining your own sub-agents and using slash commands — and can now place skills, sub-agents, workflows, and slash commands in one picture.
