Struct SubAgentConfig

pub struct SubAgentConfig {
    pub name: String,
    pub description: String,
    pub instructions: String,
    pub model: Option<Arc<dyn LanguageModel>>,
    pub tools: Option<Vec<Arc<dyn Tool>>>,
    pub builtin_tools: Option<HashSet<String>>,
    pub enable_prompt_caching: bool,
}

Configuration for creating and registering a subagent using a simple, Python-like shape.

Configuration for a sub-agent - a full AI agent with its own LLM, tools, and memory.

A sub-agent is just like the main agent: it has its own system instructions, tools, LLM, and can maintain its own conversation history. The main agent delegates tasks to sub-agents via the task tool.

Required Fields:

• name: Unique identifier for this sub-agent
• description: What this sub-agent specializes in (shown to main agent)
• instructions: System prompt for this sub-agent

Optional Fields:

• model: LLM to use (defaults to parent agent’s model if not specified)
• tools: Tools available to this sub-agent (defaults to empty)
• builtin_tools: Built-in tools to enable (filesystem, todos, etc.)
• enable_prompt_caching: Whether to cache prompts for efficiency

Fields

name: String

description: String

instructions: String

model: Option<Arc<dyn LanguageModel>>

tools: Option<Vec<Arc<dyn Tool>>>

builtin_tools: Option<HashSet<String>>

enable_prompt_caching: bool

Implementations

impl SubAgentConfig

pub fn new( name: impl Into<String>, description: impl Into<String>, instructions: impl Into<String>, ) -> SubAgentConfig

Create a new sub-agent configuration with required fields only

pub fn with_model(self, model: Arc<dyn LanguageModel>) -> SubAgentConfig

Set the LLM model for this sub-agent

pub fn with_tools(self, tools: Vec<Arc<dyn Tool>>) -> SubAgentConfig

Set the tools for this sub-agent

pub fn with_builtin_tools(self, tools: HashSet<String>) -> SubAgentConfig

Enable specific built-in tools (filesystem, todos, etc.)

pub fn with_prompt_caching(self, enabled: bool) -> SubAgentConfig

Enable prompt caching for this sub-agent

Trait Implementations

impl IntoIterator for SubAgentConfig

type Item = SubAgentConfig

The type of the elements being iterated over.

type IntoIter = Once<SubAgentConfig>

Which kind of iterator are we turning this into?

fn into_iter(self) -> <SubAgentConfig as IntoIterator>::IntoIter

Creates an iterator from a value.
