推理器 Trait

负责 Agent 的推理/思考过程

§示例

use mofa_kernel::agent::components::reasoner::{Reasoner, ReasoningResult};
use mofa_foundation::agent::components::reasoner::DirectReasoner;

// 使用 foundation 层提供的具体实现
let reasoner = DirectReasoner;
// 或者实现自定义 Reasoner
struct MyReasoner;

#[async_trait]
impl Reasoner for MyReasoner {
    async fn reason(&self, input: &AgentInput, ctx: &CoreAgentContext) -> AgentResult<ReasoningResult> {
        Ok(ReasoningResult {
            thoughts: vec![],
            decision: Decision::Respond { content: input.to_text() },
            confidence: 1.0,
        })
    }

    fn strategy(&self) -> ReasoningStrategy {
        ReasoningStrategy::Direct
    }
}
