type InitSystemPrompt ¶

type InitSystemPrompt struct {
	*adk.BaseChatModelAgentMiddleware
	// contains filtered or unexported fields
}

InitSystemPrompt swaps the system prompt to initSystemPrompt on the very first model call (when state has exactly [system, user]). After the call, it restores the normal prompt. Subsequent calls in the same ReAct loop or later rounds are no-ops. After Clear() resets state, the init prompt fires again automatically.

func NewInitSystemPrompt(initPrompt, normal string, renderer PromptRenderer) *InitSystemPrompt

func (m *InitSystemPrompt) AfterModelRewriteState(ctx context.Context, state *adk.ChatModelAgentState, mc *adk.ModelContext) (context.Context, *adk.ChatModelAgentState, error)

func (m *InitSystemPrompt) BeforeModelRewriteState(ctx context.Context, state *adk.ChatModelAgentState, mc *adk.ModelContext) (context.Context, *adk.ChatModelAgentState, error)
