Anthropic's official "Code with Claude" workshop materials — nine hands-on courses on skills, MCP, evals and Claude Managed Agents.
Nine complete workshops Anthropic ran publicly: sweep an eval suite across models and inference parameters (rightmodel), decompose a 400-line-prompt agent into skills plus callable agents (agent-decomposition), reproduce Anthropic's own three-phase product workflow (how-we-claude-code), ship a first Claude Managed Agent through seven small API calls (ship-your-first-managed-agent), compete on agent configs (agent-battle), layer in memory primitives and a dreaming service (agents-that-remember), iterate a PPTX-generating agent through six measured variants (eval-driven-agent-development), coordinate a multi-agent M&A research team (production-ready-agent), and build an SEC-filings research desk with sub-agents and scorecards (research-desk).
The fastest official path from "I use Claude Code" to "I architect multi-agent systems": pick the workshop matching your gap and work it hands-on. Also prime material for teams running internal Claude training.
Nothing to install — clone the repo and open each workshop folder's README: git clone https://github.com/anthropics/cwc-workshops cd cwc-workshops/rightmodel # or any of the nine
Explicitly labeled "Not maintained and not accepting contributions" — treat it as archived courseware, not a living product (links and Managed Agents APIs will drift). Apache-2.0. Assumes existing comfort with Claude Code, skills and MCP.
