Learn the agent loop that everything else builds on.https://datatweets.com/courses/ai-agents/agent-foundations/lesson-2-agents-vs-workflows/Fri, 19 Dec 2025 09:00:00 +0200https://datatweets.com/courses/ai-agents/agent-foundations/lesson-2-agents-vs-workflows/Workflows run a fixed path you coded; agents let the model decide each step at runtime. Learn the trade-offs and a four-part checklist — complexity, value, viability, and cost of error — for choosing an agent only when the task truly needs one.https://datatweets.com/courses/ai-agents/agent-foundations/lesson-3-the-anatomy-of-an-agent/Fri, 19 Dec 2025 09:00:00 +0200https://datatweets.com/courses/ai-agents/agent-foundations/lesson-3-the-anatomy-of-an-agent/Every agent is built from the same parts: a model, instructions, tools, the loop that runs them, memory, and stopping conditions. Learn what each does and how they compose into an agent, mapped onto the Atlas trip-planning agent you’ll build.https://datatweets.com/courses/ai-agents/agent-foundations/lesson-4-your-first-claude-call/Fri, 19 Dec 2025 09:00:00 +0200https://datatweets.com/courses/ai-agents/agent-foundations/lesson-4-your-first-claude-call/Get from zero to a working Claude API call: install the anthropic SDK, store your API key as an environment variable, send a message with the model, system prompt, and messages, and read the text, stop reason, and token usage from the response.https://datatweets.com/courses/ai-agents/agent-foundations/lesson-5-guided-project-design-the-atlas-agent/Fri, 19 Dec 2025 09:00:00 +0200https://datatweets.com/courses/ai-agents/agent-foundations/lesson-5-guided-project-design-the-atlas-agent/Apply everything from Module 1 to design Atlas, a trip-planning agent: define its goal and system prompt, justify it as an agent, sketch its tools, map its anatomy, and trace the decide-act-observe loop for a sample request.
