Building Agents with Claude

Anthropic · 47:23

Key Insight

Effective agents need structured tool access — not just bigger context windows.

Summary

This talk breaks down the core architecture for building AI agents: tool use, memory management, and multi-step orchestration. Start simple, add autonomy incrementally, and always keep humans in the loop for high-stakes decisions.

Key Takeaways
Tool use separates chatbots from agents
Structure memory explicitly
Start simple, add autonomy over time

A library that thinks for itself

Every video you add makes every other video more valuable. Ideas connect, themes emerge, and your library grows into something greater than its parts.
