Know how they work
Explain separate context windows, how inputs are passed in, and how summaries come back to the main agent.

Overview
One long session fills its own context. Subagents keep the main thread clear.
Introduction to subagents is a 45-minute Academy course on handing work to helper agents, each with its own context window. You build subagents for jobs like code review and documentation, limit their tools, and learn when delegation pays off. Anthropic’s course page says it has no completion badge, so finishing it earns no credential; it has four lessons and no quiz.

Create custom subagents
Ask Claude to write subagents for jobs such as code review and documentation, and adjust them.
Make them reliable
Use structured output formats, obstacle reporting and limited tool access so subagents behave predictably.
Judge when to use them
Spot where subagents help most, and avoid the common anti-patterns that waste them.
Course outline
From one context window
From one context window
to helpers with their own.
We design this course ourselves. Anthropic issues the credential, and LUNARTECH is independent of Anthropic.
A subagent is a helper with its own context window. You learn how work is handed in, why only a summary returns, and what that does to the main conversation.
- The problem of a crowded context window
- A subagent’s separate context
- How inputs are passed in
- How a summary comes back
- Subagents compared with the main agent
You build A diagram that traces a task into a subagent and its summary back out.
You ask Claude to write a subagent for a real job, such as code review or documentation, then read what it produced and adjust it to fit.
- Where subagent definitions live
- Asking Claude to draft a subagent
- A code review subagent
- A documentation subagent
- Reading and editing the definition
You build A code review subagent and a documentation subagent, each tried on real code.
A main agent can only use what comes back. You define structured output formats and make subagents report obstacles, so results are consistent and problems are not hidden.
- Why free-form summaries fail
- Defining a structured output format
- Reporting obstacles instead of guessing
- Handling a partial result
- Testing the report format
You build A subagent whose reports follow a fixed format and flag every obstacle.
A subagent should only be able to do its job. You restrict its tools, give it a narrow purpose, and see how limited access makes behavior predictable.
- Why limited tools help
- Choosing a tool list per subagent
- Read-only and write-capable subagents
- Narrow purpose and clear descriptions
- Checking what a subagent actually used
You build A set of subagents with minimal tool lists, each matched to its job.
Delegation has a cost. You learn where subagents help most, how to spot the common anti-patterns that waste them, and how to decide whether a task deserves one.
- Tasks where subagents pay off
- Parallel work and noisy tasks
- Common anti-patterns
- When a plain prompt is better
- Reviewing a session for wasted delegation
You build A review of one real session, marking where subagents helped and where they did not.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
