Struct SimpleAgent 

pub struct SimpleAgent { /* private fields */ }

Canonical Agent implementation for the String → String case.

Wraps the boilerplate every example repeats: append the user message to short-term memory, delegate to crate::runtime::run_steps with the supplied system prompt.

Custom-typed agents (non-String input or output, alternative turn shapes) still implement Agent by hand; SimpleAgent is shortcut, not replacement.

use klieo_core::{Agent, SimpleAgent};
let agent = SimpleAgent::new("hello", "Be brief.", vec![]);
assert_eq!(agent.name(), "hello");
assert_eq!(agent.system_prompt(), "Be brief.");
assert!(agent.tools().is_empty());

Implementations

impl SimpleAgent

pub fn new( name: impl Into<String>, system_prompt: impl Into<String>, catalogue: Vec<ToolDef>, ) -> Self

Build a SimpleAgent with the supplied name, system prompt, and tool catalogue. Uses crate::runtime::RunOptions::default — override via SimpleAgent::with_run_options.

pub fn with_run_options(self, options: RunOptions) -> Self

Override the crate::runtime::RunOptions passed to crate::runtime::run_steps.

pub fn with_review_policy(self, policy: Arc<dyn ReviewPolicy>) -> Self

Install a review policy (the ADR-045 HITL suspend gate) on this agent’s run options. Composes with SimpleAgent::with_run_options: every other option field keeps its configured value; only the review policy is replaced.

Trait Implementations

impl Agent for SimpleAgent

type Input = String

Input payload type.

type Output = String

Output payload type.

type Error = Error

Domain-specific error type. Wrap crate::Error if you don’t need a custom one.

fn name(&self) -> &str

Stable agent name (used in spans + episodic events).

fn system_prompt(&self) -> &str

System prompt prepended to the conversation.

fn tools(&self) -> &[ToolDef]

Tool catalogue this agent advertises to the LLM.

fn run<'life0, 'async_trait>( &'life0 self, ctx: AgentContext, input: String, ) -> Pin<Box<dyn Future<Output = Result<String, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Run one turn. Runtime supplies ctx; agent owns the per-call shape.
