用 AI Bot 打造顧問團隊（三）：評估、維運與優化計畫

前言 你已經建好了 AI 顧問 Agent 團隊（第一篇、第二篇），現在問題來了： 「這系統真的有在正常工作嗎？品質夠好嗎？出了問題怎麼辦？」 AI Agent 系統不像傳統軟體，你不能只看 HTTP 200。你需要評估輸出品質、追蹤推理過程、並且在 LLM 開始說廢話之前就發現它。 本篇從 DevOps/SRE 的角度，完整說明如何讓 AI 顧問團隊穩定、可觀測、持續進化。 一、系統效能評估：怎麼知道 Agent 表現好不好？ 1.1 評估的四個維度 品質（Quality） → 輸出內容是否正確、有用、符合顧問標準 速度（Latency） → 每個 Agent 節點的回應時間 成本（Cost） → 每次顧問對話的 Token 花費 可靠性（Reliability）→ 成功完成整個流程的比率 1.2 建立評估資料集（Golden Dataset） 這是最重要的第一步。準備 20-50 個有代表性的客戶案例： 1# evaluation/golden_dataset.py 2GOLDEN_CASES = [ 3 { 4 "id": "case-001", 5 "input": "我們是一家 50 人的電商公司，客服每天要處理 500 封郵件，想用 AI 減輕負擔。", 6 "expected_intake": { 7 "industry": "電商", 8 "size": "50人", 9 "pain_points": ["客服郵件量大"], 10 "ai_type": "自動化" 11 }, 12 "expected_strategy_keywords": ["聊天機器人", "郵件分類", "自動回覆"], 13 "quality_rubric": { 14 "relevance": "策略必須針對客服場景", 15 "feasibility": "建議的方案在 100 萬預算內可行", 16 "actionability": "至少有 3 個具體的下一步行動" 17 } 18 }, 19 # .

用 AI Bot 打造顧問團隊（一）：策略與技術路線選擇

前言 想像你是一家小型 AI 顧問公司的創辦人。客戶問你：「我們公司要怎麼導入 AI？」 你不可能 24 小時隨時接電話，但 AI Bot 可以。 這個系列文章將帶你從零開始，用純 Bot 建立一支能夠： 接受客戶需求、提問、釐清問題 產出顧問報告草稿 自動分派任務給不同專業角色 追蹤執行狀況並彙整成果 的 AI 顧問團隊。 本篇（第一篇）專注在策略層面：應該選哪條技術路線？各自的優缺點和適用場景是什麼？ 商業背景：我們要解決什麼問題？ 根據 ai_consultant 這個商業計劃的核心理念，AI 顧問的工作可以拆成幾個主要環節： 客戶需求輸入 → 問題釐清與診斷 → 方案設計 → 報告產出 → 執行追蹤 傳統顧問公司靠人來完成每個環節。我們的目標是： 用一組協作的 AI Agent 取代或增強每個環節，讓少數人力就能服務更多客戶。 這不是「一個超級 AI 什麼都做」，而是多個專責 Agent 分工合作的概念。 三條技術路線 路線 A：Claude Code + Skills / AGENTS.md 核心概念： 利用 Claude Code CLI 的原生 multi-agent 機制，透過 AGENTS.md（或 CLAUDE.md）定義每個 Agent 的角色、工具權限與行為邊界，搭配 Skills（可重複呼叫的 slash command 腳本）讓 Agent 之間能互相協作。
