Per-turn request shape: ChatRequest plus ToolChoice, ToolDefinition, and ToolTag.

Structs

ChatRequest

Per-turn request the engine assembles and the adapter lowers to the provider’s wire format.

ToolDefinition

Tool description sent to the provider so the model can decide when and how to call it.

Enums

ToolChoice

Constraint placed on the model’s tool selection for a single request. Variant naming follows Anthropic’s wire vocabulary; the Chat Completions adapter translates Any → "required" and None_ → "none".

ToolTag
