兩項目評估報告
- EvalRun: #38(suite #30
auto-d4ddb6f9-r1-053958294)
- Target: #2 production-canary
- Cases: 13(N=1, attempts=13/13)
- Generated: 2026-05-16T12:25:41+08:00
本報告含兩個獨立評估項目。項目一 評估 bot 進入「知識與產品查詢」fallback
後的撈取 + 回答能力;項目二 評估 bot 跨全 enabled scenarios 的 routing →
tool → answer 三段 funnel 健康度。
項目一: 知識庫精準度
評估範圍 (prerequisite: 進對 scenario)
- 進對 scenario 的 attempts: 10 / 13 (76.9%)
- 只對這些 attempts 算 retrieval + answer
- 沒進對 scenario 的 attempts → 排除(routing 失敗不該污染 KB 訊號)

待修方向(worst-3)
- 知識與產品查詢 × retrieval_relevance = 0.0% — bot 進對 scenario 但沒呼叫 search tool — 流程 / prompt 問題(不是 KB content gap)
