//! Build the `CompletionRequest` used to ask the router model for a plan.

use crate::provider::{CompletionRequest, ContentPart, Message, Role};

use super::prompt::{ROUTER_SYSTEM, build_user_prompt};

/// Construct the provider request carrying the router prompt.
///
/// `temperature = 1.0` keeps the request compatible with the Z.AI GLM
/// family (see project AGENTS notes on GLM-5.1 temperature).
///
/// # Examples
///
/// ```rust
/// use codetether_agent::search::request::build_router_request;
/// let req = build_router_request("glm-5.1", "find fn main", 1);
/// assert_eq!(req.messages.len(), 2);
/// ```
