Struct ReActAgentBuilder 

pub struct ReActAgentBuilder { /* private fields */ }

Builder for assembling a ReActAgent from the same components used by ReActAgent::new, plus optional runtime configuration.

The builder is only an assembly helper: provider calls still go through the agent loop, immediate tools still run through the tool registry, and governed side effects still belong to the outer harness/kernel path. Skill assembly is handled by the molo-skills layer so ReActAgent does not own skill policy.

Examples

use molo::{Agent, FakeProvider, FakeReply, ReActAgent};

let mut agent = ReActAgent::builder(FakeProvider::new([
    FakeReply::Text("Hello".into()),
]))
.with_system_prompt("You are a helpful assistant")
.build();

assert_eq!(agent.run("Are you there").await?, "Hello");

Implementations

impl ReActAgentBuilder

pub fn new(provider: impl Provider + 'static) -> ReActAgentBuilder

Starts a builder with a provider and default optional components.

pub fn with_provider( self, provider: impl Provider + 'static, ) -> ReActAgentBuilder

Replaces the provider.

pub fn with_tools(self, tools: ToolRegistry) -> ReActAgentBuilder

Replaces the tool registry.

pub fn with_tool(self, tool: impl Tool + 'static) -> ReActAgentBuilder

Registers one tool into the builder’s registry.

pub fn with_system_prompt( self, system_prompt: impl Into<String>, ) -> ReActAgentBuilder

Sets the system prompt. Empty means no system message is assembled.

pub fn with_memory(self, memory: impl Memory + 'static) -> ReActAgentBuilder

Replaces the default Memory.

pub fn with_config(self, config: AgentConfig) -> ReActAgentBuilder

Replaces the agent config.

pub fn with_structured_output(self, schema: Value) -> ReActAgentBuilder

Enables structured output for Agent::run.

pub fn with_state(self, state: SharedState) -> ReActAgentBuilder

Attaches shared state for tool calls.

pub fn with_event_channel( self, channel: impl EventChannel + 'static, ) -> ReActAgentBuilder

Attaches an observation channel.

pub fn with_tool_round_executor( self, executor: impl ToolRoundExecutor + 'static, ) -> ReActAgentBuilder

Replaces the tool-round executor.

pub fn build(self) -> ReActAgent

Builds the agent.
