Guides are short, task-oriented recipes — each one walks through a single “How do I…” end to end. For complete API and concept reference, see the Docs.
Guides are primarily made for AI Agents, they are written for clarity over conciseness and include more case-specific details than docs for humans do. They are oriented towards helping agents follow paths we know work, and knowing how to avoid/handle sharp edges.
For humans, we recommend chatting with an agent about them rather than reading them top to bottom.
