About
Anthropic's official recipe collection — ~80 notebooks, fully MIT. The 2026 layer is the value: the Agent SDK tutorial series (00–06), the Managed Agents series (Outcomes self-grading, multiagent coordination, vault credentials), context engineering, programmatic tool calling, and the Fable 5 fallback-and-billing guide. A skills/ subfolder teaches running skills over the Messages API. registry.yaml is a machine-readable catalog of every recipe — title, path, date, categories — consumable as a feed. Every notebook is a wrap candidate.
