潜在风险 (Sharp Edges)
Agent 在基准测试中得分很高,但在生产环境中失败
严重程度:高 (HIGH)
场景:高基准测试分数无法预测实际运行性能
症状:
- 基准测试分数高,但用户满意度低
- 出现测试中未见过的生产环境错误
- 在真实负载下性能下降
失效原因:
- 基准测试具有已知的答案模式。
- 生产环境存在长尾边缘案例。
- 用户输入比测试数据更杂乱。
建议修复方案:
// 弥合基准测试与生产评估之间的差距
class ProductionReadinessEvaluator {

同一测试有时通过,有时失败
严重程度:高 (HIGH)
场景:测试套件不可靠,CI 损坏或被忽略
症状:
- CI 随机失败
- 测试在本地通过,但在 CI 中失败
- 重新运行可修复测试失败
失败原因:
LLM 的输出具有随机性。
测试期望确定性的行为。
缺乏重试机制或统计处理。
推荐修复方案:
// 处理 LLM Agent 评估中的不稳定测试 (Flaky Tests)

Agent 针对指标而非实际任务进行了优化
严重程度:中 (MEDIUM)
场景:Agent 在指标上得分很高,但实际质量较差
症状:
- 指标得分高,但用户反馈差
- 尽管得分良好,但 Agent 行为感觉“不对劲”
- 当指标发生变化时,刷分(Gaming)现象变得明显
失效原因:
指标只是质量的代理指标。
Agent 可能会针对特定指标进行“刷分”。
对评估标准过度拟合。

测试数据被误用于训练或 Prompt
严重程度:CRITICAL (极其严重)
场景:Agent 已经见过测试样例,导致分数虚高
症状:
- 在特定测试用例上获得满分
- 在新版本的测试集上分数骤降
- Agent “知道”它本不该知道的答案
失效原因:
- 测试数据进入了微调数据集。
- 示例出现在系统 Prompt 中。
- RAG 检索到了测试文档。

协作
委派触发条件
- implement|fix|improve -> autonomous-agents (需要修复评估中发现的问题)
- orchestration|coordination -> multi-agent-orchestration (需要评估编排模式)
- communication|message -> agent-communication (需要评估通信机制)
