Agent Frameworks

A 12-minute orientation to the Agent Frameworks skill path — why it exists, what you'll be able to do, how the chapters relate, and where to begin.

Navigate the API-to-agent stack across OpenAI and Anthropic — understand the layers before you build.

Master both the Responses API and Chat Completions — understand when to use each and how to migrate.

Master the Messages API, tool use, extended thinking, and prompt caching — build with Claude from first principles.

Build multi-agent systems with guardrails, handoffs, and tracing — OpenAI's framework for autonomous AI.

Build autonomous agents with Anthropic's framework — the same engine that powers Claude Code, as a library you control.

Ship multi-agent systems that integrate with real tools, scale in containers, and verify their own work.

Ship agents you can verify — mock tools, trace decisions, build golden datasets, and gate deploys on eval results.

Read, debug, and ship across LangGraph, CrewAI, and AutoGen — the three frameworks you'll meet in customer code.
