An Anthropic senior engineer just released a one-hour course on constructing agentic systems using Claude from the ground up. This workshop is described as replacing ten paid courses on agentic engineering. The operational mechanics of Claude Code start at 00:37, while instruction on creating CLAUDE.md and Plan files for agents begins at 02:29. Guidance on defining /skills for Claude agents is presented at 25:38, followed by design patterns for teams of Claude agents discussed at 45:39. The Agents SDK, including subagents, loops, and graphs, gets explained at 52:10. A link to an article about building self-learning agentic systems with loops and graphs is provided below the post. #ClaudeCode
