}

type Executor

type Executor struct {
	// contains filtered or unexported fields
}

Executor represents an agent executor that executes a chain of actions based on inputs and a defined agent model.

func NewConversationalReactDescription

func NewConversationalReactDescription(llm schema.Model, tools []schema.Tool) (*Executor, error)

func NewExecutor

func NewExecutor(agent schema.Agent, tools []schema.Tool) (*Executor, error)

NewExecutor creates a new instance of the Executor with the given agent and a list of available tools.

func NewOpenAIFunctions

func NewOpenAIFunctions(model schema.ChatModel, tools []schema.Tool) (*Executor, error)

NewOpenAIFunctions creates a new instance of the OpenAIFunctions agent with the given model and tools. It returns an error if the model is not an OpenAI chatModel or fails to convert tools to function definitions.

func NewReactDescription

func NewReactDescription(llm schema.Model, tools []schema.Tool) (*Executor, error)

func (Executor) Call

func (e Executor) Call(ctx context.Context, inputs schema.ChainValues, optFns ...func(o *schema.CallOptions)) (schema.ChainValues, error)

Call executes the AgentExecutor chain with the given context and inputs. It returns the outputs of the chain or an error, if any.

func (Executor) Callbacks

func (e Executor) Callbacks() []schema.Callback

Callbacks returns the callbacks associated with the chain.

func (Executor) InputKeys

func (e Executor) InputKeys() []string

InputKeys returns the expected input keys.

func (Executor) Memory

func (e Executor) Memory() schema.Memory

Memory returns the memory associated with the chain.

func (Executor) OutputKeys

func (e Executor) OutputKeys() []string

OutputKeys returns the output keys the chain will return.

func (Executor) Type

func (e Executor) Type() string

Type returns the type of the chain.

func (Executor) Verbose

func (e Executor) Verbose() bool

Verbose returns the verbosity setting of the chain.

type ExecutorOptions

type ExecutorOptions struct {
	*schema.CallbackOptions
	MaxIterations int
	Memory        schema.Memory
}

ExecutorOptions holds configuration options for the Executor.

type OpenAIFunctions

type OpenAIFunctions struct {
	// contains filtered or unexported fields
}

OpenAIFunctions is an agent that uses OpenAI chatModels and schema.Tools to perform actions.

func (*OpenAIFunctions) InputKeys

func (a *OpenAIFunctions) InputKeys() []string

InputKeys returns the expected input keys for the agent.

func (*OpenAIFunctions) OutputKeys

func (a *OpenAIFunctions) OutputKeys() []string

OutputKeys returns the output keys that the agent will return.

func (*OpenAIFunctions) Plan

func (a *OpenAIFunctions) Plan(ctx context.Context, intermediateSteps []schema.AgentStep, inputs schema.ChainValues) ([]*schema.AgentAction, *schema.AgentFinish, error)

Plan executes the agent with the given context, intermediate steps, and inputs. It returns the agent actions, agent finish, or an error, if any.

type OpenAIFunctionsOptions

type OpenAIFunctionsOptions struct {
	// OutputKey is the key to store the output of the agent in the ChainValues.
	OutputKey string
}

OpenAIFunctionsOptions represents the configuration options for the OpenAIFunctions agent.

	Prefix       string
	Instructions string
	Suffix       string
	OutputKey    string
}
