Claude Skills: The NEW Way to Build AI Agents (Live Tutorial)
The Startup Ideas Podcast
What Are Sub-agents and When to Use Them
Amir describes sub-agents in Claude Code that split complex workflows into specialized, isolated conversational agents.
In this episode, Amir takes us through how to use Claude Skills to build digital employees. We cover practical demos including an A/B testing idea agent, marketing insight analyzer, and a live build of a tweet-to-newsletter converter. You'll learn what Claude Skills actually are, why they represent the biggest leap since sub-agents, and how to build them yourself—even if you've never written a custom AI workflow before.

Key Points
Claude Skills are automated workflows that apply globally or per-project, pulling context only when relevant to specific tasks
Skills solve the "context rot" problem where too much context degrades LLM performance and increases hallucination
You can create custom Skills using markdown files with instructions, reference documents, and executable scripts
The tweet-to-newsletter converter built live demonstrates Skills' ability to match tone and style with minimal training
Poor AI fluency and prompting—not the tools themselves—explain why enterprise AI adoption is declining
