ToolKind

@Serializable

sealed interface ToolKind(source)

The protocol-independent meaning of a tool call. Backends map their protocol onto it (an on-device tool declares it, AG-UI SUBAGENT_* runs and the Pydantic AI Harness tool conventions are translated in core), so UI elements only ever look at this.
