I build AI-powered tools that help people work smarter. You might know my other projects:
The session analyser for AI-assisted development. Upload a Claude Code transcript and get scored across 8 fluency dimensions — with actionable recommendations.
A VSCode extension that monitors your Claude Code sessions in real-time — live health scores, anti-pattern alerts, and per-model cost tracking, right inside your editor.
Building these tools, I kept noticing the same pattern: the developers who get the most leverage from Claude Code aren't the ones with the cleverest prompts — they're the ones who know when to delegate work into a subagent and when to keep it in the main thread.
Introduction to Subagents is a focused micro-course on one of the most underused features in Claude Code: subagents — specialized assistants that run in their own isolated context windows, do focused work, and return just a summary to your main thread.
In four short lessons you'll learn what subagents are, how to create one with the /agents command, four design patterns that make them effective, and a decision framework for when to use them versus keeping work in your main conversation.
The whole course takes about 30 minutes and is completely free.
Most developers I talk to either don't know subagents exist, or they've tried them once and given up because the results felt unpredictable. The truth is that subagents are powerful, but they have a learning curve — you need to understand context isolation, structured output formats, and which tasks actually benefit from delegation.
I built this course to flatten that learning curve. Every lesson is grounded in real Claude Code workflows: a code-quality reviewer subagent runs as the worked example throughout, and the final lesson distils the use-for / avoid-for tradeoffs into a single decision rule you can apply on the fly.
If you use Claude Code regularly, this is a 30-minute investment that should pay back the first time you delegate a research task and keep your main context clean.
