Helper Methods

The following helper methods are declared via @method and must be implemented by every runtime. The schema declares the logical protocol contract; each runtime maps async-capable methods to idiomatic sync/async shapes for that language.

Name	Signature	Runtime shape	Description
execute	execute(agent: Prompty, messages: Message[]) -> unknown	async-capable	Call an LLM provider with messages and return the raw response
executeStream	executeStream(agent: Prompty, messages: Message[]) -> unknown	async-capable (optional default)	Call an LLM provider and return a streaming response. Returns a language-specific async iterable/stream of raw chunks. Not all providers support streaming; the default implementation should signal lack of support.
formatToolMessages	formatToolMessages(rawResponse: unknown, toolCalls: ToolCall[], toolResults: string[], textContent: string?) -> Message[]	sync	Format tool call results into messages for the next iteration
