Overview ¶
Package agentfactory builds ADK-compatible agents from runtime config.
A Factory holds provider definitions plus MCP server lookup and exposes Factory.Build for runtime agent construction. It also exposes Factory.BuildSessionState for canonical session-state initialization that stays stable across provider backends.

Types ¶
type BuildRequest ¶
type BuildRequest struct {
// AgentID selects a provider entry from the factory registry.
AgentID string `json:"agent_id" validate:"required,min=1"`
// Name overrides the runtime agent display name.
Name string `json:"name,omitempty"`
// Description overrides the runtime agent description.
Description string `json:"description,omitempty"`
// Instruction overrides the provider-specific invocation instruction.
Instruction string `json:"instruction,omitempty"`
// GlobalInstruction is prepended ahead of Instruction for each invocation.
GlobalInstruction string `json:"global_instruction,omitempty"`
// WorkingDirectory is the session working directory for the built agent.
WorkingDirectory string `json:"working_directory" validate:"required,min=1"`
// MCPServerIDs overrides provider-level MCP server references for this build.
MCPServerIDs []string `json:"mcp_server_ids,omitempty"`
// SessionID requests a specific remote session identifier when supported.
SessionID string `json:"session_id,omitempty"`
}
BuildRequest defines the parameters for building a new agent instance.
func (BuildRequest) Validate ¶
func (r BuildRequest) Validate() error
Validate validates the build request.
type Factory ¶
type Factory struct {
// contains filtered or unexported fields
}
Factory is a registry of agent configurations.
func New ¶
func New(agents map[string]agentconfig.Config, mcp mcpregistry.Reader, opts ...Option) *Factory
New creates a new Factory from agent configurations and an MCP registry.
func (*Factory) BuildSessionState ¶
BuildSessionState builds canonical ADK session state for runtime sessions.
The returned state is backend-agnostic and currently always includes the canonical per-session working directory at key sessionstate.CWDKey.
Example ¶
workspaceDir, err := os.MkdirTemp("", "runtime-agentfactory-example-*")
if err != nil {
fmt.Println(err)
return
}
defer func() { _ = os.RemoveAll(workspaceDir) }()
factory := New(map[string]agentconfig.Config{
"openai": {
Type: agentconfig.AgentTypeOpenAI,
OpenAI: &agentconfig.LocalAPIConfig{
APIKey: "test-key",
Model: "gpt-5",
},
},
}, mcpregistry.New(nil))
state, err := factory.BuildSessionState("openai", workspaceDir)
if err != nil {
fmt.Println(err)
return
}
cwd, _ := state[sessionstate.CWDKey].(string)
fmt.Println(filepath.IsAbs(cwd))
Output: true
func (*Factory) GetAgentConfig ¶
func (f *Factory) GetAgentConfig(agentID string) (agentconfig.Config, error)
GetAgentConfig returns the schema configuration for agentID.
func (*Factory) ValidateAgent ¶
ValidateAgent checks if an agent with agentID can be built.
type Option ¶
type Option func(*Factory)
Option configures factory behavior.
func WithPermissionHandler ¶
func WithPermissionHandler(handler acpagent.PermissionHandler) Option
WithPermissionHandler configures a default ACP permission callback for all built agents.
func WithStderrWriter ¶
WithStderrWriter configures where ACP subprocess stderr is written.
