前言:為什麼評估比建設更重要
在 AI Agent 系統的生產部署中,建設易於實現,但「知道它是否真正有效」則難得多。許多團隊在部署後發現:
- 延遲飆升: P99 延遲從 200ms 增加到 2s
- 成本失控: 每次請求成本增加 3 倍
- 錯誤率上升: 無法預測的失敗率從 0.5% 上升到 5%
- 回報不明: 無法證明 Agent 帶來了可衡量的業務價值
本文提供一個可操作、可測量的評估框架,幫助你在生產中追蹤、診斷和優化 Agent 系統。
評估架構三層模型
第 1 層:輸入品質(Input Quality)
定義: 輸入訊號是否足夠、足夠清晰、足夠完整?
可測量指標:
- Input Completeness Rate(輸入完整性率):完整輸入占比
Input Completeness = (完整輸入數) / (總輸入數) × 100%- 門檻:< 80% → 停止部署
- Input Clarity Score(輸入清晰度):LLM 評分(1-10)
- 門檻:< 6 → 需要輸入預處理
- Context Relevance(上下文相關性):檢索相關性分數
實作範例:
def evaluate_input_quality(input_data):
completeness = calculate_completeness(input_data)
clarity_score = llm.evaluate(input_data, prompt="Rate clarity 1-10")
relevance = search_context.get_relevance(input_data)
return {
'completeness_rate': completeness,
'clarity_score': clarity_score,
'relevance_score': relevance,
'pass_threshold': completeness >= 0.80 and clarity_score >= 6.0
}
Trade-off:
- 提高輸入完整性 → 增加預處理成本
- 提高清晰度 → 增加模型輸入 token 數量
第 2 層:處理品質(Processing Quality)
定義: Agent 在執行過程中的表現是否穩定、可預測、可追蹤?
可測量指標:
- Tool Calling Success Rate(工具調用成功率):
Success = (成功調用數) / (總調用數) × 100%- 門檻:< 95% → 立即停機
- Reasoning Latency Distribution(推理延遲分佈):
- P50, P90, P95, P99, P99.9
- Tool Selection Accuracy(工具選擇準確度):
- 正確工具選擇占比
- State Transitions(狀態轉換):
- 狀態轉換成功率、狀態異常數量
實作範例:
def evaluate_processing_quality(execution_log):
tool_calls = execution_log['tool_calls']
success_rate = sum(call['success'] for call in tool_calls) / len(tool_calls)
latency_samples = [call['duration'] for call in execution_log['tool_calls']]
p99_latency = np.percentile(latency_samples, 99)
state_transitions = execution_log['state_transitions']
transition_success = sum(t['success'] for t in state_transitions) / len(state_transitions)
return {
'tool_success_rate': success_rate,
'p99_latency_ms': p99_latency,
'transition_success_rate': transition_success
}
Trade-off:
- 增加工具選擇驗證 → 增加推理成本
- 擴展狀態追蹤 → 增加監控開銷
第 3 層:輸出品質(Output Quality)
定義: Agent 輸出是否滿足業務需求、可驗證、可接受?
可測量指標:
- Output Correctness Rate(輸出正確率):人工/自動驗證
- User Satisfaction Score(使用者滿意度):直接反饋
- Task Completion Rate(任務完成率):成功完成任務占比
- Error Recovery Rate(錯誤恢復率):自動恢復占比
實作範例:
def evaluate_output_quality(output_data, ground_truth):
correctness = calculate_correctness(output_data, ground_truth)
# 使用 LLM 進行主觀評分
satisfaction = llm.evaluate(output_data, prompt="Rate satisfaction 1-10")
# 檢查是否達成業務目標
completion = check_business_goal(output_data)
return {
'correctness_rate': correctness,
'satisfaction_score': satisfaction,
'completion_rate': completion
}
Trade-off:
- 提高正確率 → 增加驗證成本
- 增加人工審核 → 降低自動化程度
關鍵品質指標匯總表
| 指標類別 | 指標名稱 | 門檻值 | 收集頻率 | 報警閾值 |
|---|---|---|---|---|
| 輸入品質 | Completeness Rate | ≥ 80% | 每日 | < 85% |
| Clarity Score | ≥ 6 | 每小時 | < 6 | |
| 處理品質 | Tool Success Rate | ≥ 95% | 每分鐘 | < 93% |
| P99 Latency | ≤ 1s | 每分鐘 | > 2s | |
| State Transition Success | ≥ 98% | 每小時 | < 95% | |
| 輸出品質 | Correctness Rate | ≥ 90% | 每日 | < 80% |
| Satisfaction Score | ≥ 7 | 每小時 | < 6 | |
| Completion Rate | ≥ 95% | 每小時 | < 90% |
可測量指標實作模式
模式 1:延遲分佈追蹤
場景: 長時間執行的 Agent 任務需要確保 P95/P99 延遲不飆升。
實作:
from prometheus_client import Counter, Histogram
tool_latency = Histogram(
'agent_tool_latency_seconds',
'Agent tool call latency',
['tool_name', 'status']
)
tool_calls = Counter(
'agent_tool_calls_total',
'Total tool calls',
['tool_name', 'status']
)
# 記錄每次調用
with tool_latency.labels(tool_name='get_weather', status='success').time():
result = get_weather(location)
tool_calls.labels(tool_name='get_weather', status='success').inc()
# 查詢 P95
p95_latency = tool_latency.labels(tool_name='get_weather').percentile(95)
Trade-off:
- 精細化分組 → 更精確的診斷,但增加指標開銷
- 降低收集頻率 → 降低監控開銷,但可能延誤問題發現
模式 2:成本追蹤與 ROI 測量
場景: 每次請求的 API 成本需要與業務價值對比。
實作:
def calculate_cost_per_task(task_id):
# API 成本
api_cost = get_api_costs(task_id)
# 人力成本節省
labor_saving = estimate_labor_saving(task_id)
# ROI 計算
roi = (labor_saving - api_cost) / api_cost
return {
'api_cost_usd': api_cost,
'labor_saving_usd': labor_saving,
'roi': roi,
'break_even_tasks': api_cost / labor_saving_per_task
}
門檻:
- ROI < 1.0 → 立即停用
- ROI < 1.5 → 重新評估
- ROI ≥ 2.0 → 擴展部署
Trade-off:
- 增加詳細成本追蹤 → 更精確的 ROI,但增加開銷
- 使用粗略估算 → 降低開銷,但 ROI 測量不準確
模式 3:錯誤分類與根因分析
場景: 確保錯誤不重複發生,並追蹤錯誤類型趨勢。
實作:
class ErrorClassifier:
def classify(self, error):
# 使用 LLM 分類錯誤
classification = llm.classify(error, prompt="Classify error type: input, tool, reasoning, output")
# 追蹤錯誤模式
self.track_error_pattern(classification, error)
return classification
error_stats = {
'input_errors': 12,
'tool_errors': 45,
'reasoning_errors': 8,
'output_errors': 3
}
Trade-off:
- 增加錯誤分類粒度 → 更精確的根因分析,但增加推理成本
- 合併錯誤類別 → 降低成本,但降低診斷能力
實際部署邊界與限制
邊界 1:輸入預處理的門檻
問題: 輸入不完整或不清晰時,應拒絕處理還是嘗試補充?
決策邊界:
- 補充策略:適用於「必要資訊不足」但「可安全補充」的場景
- 門檻:補充成功率 ≥ 95%
- 拒絕策略:適用於「必要資訊缺失」且「無法安全補充」的場景
- 門檻:補充成功率 < 80%
實作:
def should_supplement_input(input_data):
required_fields = get_required_fields(input_data)
missing = required_fields - input_data.keys()
if not missing:
return False
# 評估補充可能性
supplementability = evaluate_supplementability(missing, input_data)
return supplementability >= 0.95
邊界 2:工具調用失敗的恢復策略
問題: 工具調用失敗時,應重試、回退還是終止?
決策邊界:
- 重試策略:適用於「暫時性失敗」且「可安全重試」
- 門檻:重試成功率 ≥ 90%
- 回退策略:適用於「可替代工具」
- 門檻:替代成功率 ≥ 95%
- 終止策略:適用於「永久性失敗」或「風險過高」
- 門檻:無替代方案或風險不可接受
實作:
def handle_tool_failure(tool_call):
error_type = classify_error(tool_call['error'])
if error_type == 'temporary':
retries = 3
success = try_retries(tool_call, retries)
return success if success else fallback()
elif error_type == 'recoverable':
fallback_tool = find_alternative(tool_call['tool'])
return execute_tool(fallback_tool)
else: # permanent or high-risk
terminate_task()
notify_user()
邊界 3:監控開銷與業務價值的平衡
問題: 多精細的監控會增加多少成本?
計算:
def calculate_monitoring_overhead():
# 每次請求的監控開銷
monitoring_cost_per_request = (
sampling_rate * sampling_cost +
metric_aggregation_cost * aggregation_interval +
alerting_cost * alert_threshold
)
# 對比業務價值
value_per_request = calculate_business_value()
overhead_ratio = monitoring_cost_per_request / value_per_request
return overhead_ratio
門檻:
- Overhead Ratio < 10% → 可接受
- Overhead Ratio ≥ 20% → 重新評估監控粒度
評估設計原則
原則 1:可操作性優先
原則: 所有評估指標必須在生產環境中可操作,不能僅限於離線分析。
實作:
# ❌ 錯誤:離線分析
def offline_evaluation():
return analyze_historical_logs()
# ✅ 正確:實時可操作
def live_evaluation():
if latency_p99 > 2000:
pause_deployment()
notify_team()
原則 2:門檻值明確化
原則: 每個指標必須有明確的門檻值,超過門檻立即採取行動。
實作:
# 定義門檻
THRESHOLDS = {
'tool_success_rate': 0.95,
'p99_latency_ms': 2000,
'correctness_rate': 0.90
}
# 實時檢查
def check_thresholds(metrics):
for metric, threshold in THRESHOLDS.items():
if metrics[metric] < threshold:
action = get_action_for_threshold(metric, threshold)
action.execute()
原則 3:分層報告與行動
原則: 不同層級的監控團隊看到不同粒度的報告。
報告層級:
- L1:運維層 - 即時指標,門檻報警
- L2:技術層 - 細粒度診斷,根因分析
- L3:業務層 - ROI 指標,業務價值
實作:
def generate_reports(metrics):
l1_report = {
'alert_status': 'active' if any(metrics < THRESHOLDS) else 'normal',
'critical_metrics': [m for m in metrics if metrics[m] < THRESHOLDS[m]]
}
l2_report = {
'root_cause': diagnose(metrics),
'recommendations': get_recommendations(metrics)
}
l3_report = {
'roi': calculate_roi(metrics),
'business_value': calculate_business_value(metrics)
}
return l1_report, l2_report, l3_report

Preface: Why evaluation is more important than construction
In production deployments of AI Agent systems, building is easy to implement, but knowing whether it actually works is much harder. Many teams find after deployment:
- Latency Surge: P99 latency increased from 200ms to 2s
- Cost Out of Control: Cost per request increased by 3x
- Error rate increased: Unpredictable failure rate increased from 0.5% to 5%
- Unknown Return: Unable to prove that Agent delivers measurable business value
This article provides an actionable, measurable evaluation framework to help you track, diagnose, and optimize Agent systems in production.
Evaluation architecture three-layer model
Layer 1: Input Quality
Definition: Is the input signal sufficient, clear enough, and complete enough?
Measurable indicators:
- Input Completeness Rate: proportion of complete input
Input Completeness = (完整輸入數) / (總輸入數) × 100%- Threshold: < 80% → Stop deployment
- Input Clarity Score: LLM score (1-10)
- Threshold: < 6 → input preprocessing required
- Context Relevance: Retrieve the relevance score
Implementation example:
def evaluate_input_quality(input_data):
completeness = calculate_completeness(input_data)
clarity_score = llm.evaluate(input_data, prompt="Rate clarity 1-10")
relevance = search_context.get_relevance(input_data)
return {
'completeness_rate': completeness,
'clarity_score': clarity_score,
'relevance_score': relevance,
'pass_threshold': completeness >= 0.80 and clarity_score >= 6.0
}
Trade-off:
- Improve input integrity → increase preprocessing costs
- Improve clarity → increase the number of model input tokens
Layer 2: Processing Quality
Definition: Is the Agent’s performance stable, predictable, and traceable during execution?
Measurable indicators:
- Tool Calling Success Rate:
Success = (成功調用數) / (總調用數) × 100%- Threshold: < 95% → Immediate shutdown
- Reasoning Latency Distribution:
- P50, P90, P95, P99, P99.9
- Tool Selection Accuracy:
- Proportion of correct tool selection
- State Transitions:
- State transition success rate, number of state exceptions
Implementation example:
def evaluate_processing_quality(execution_log):
tool_calls = execution_log['tool_calls']
success_rate = sum(call['success'] for call in tool_calls) / len(tool_calls)
latency_samples = [call['duration'] for call in execution_log['tool_calls']]
p99_latency = np.percentile(latency_samples, 99)
state_transitions = execution_log['state_transitions']
transition_success = sum(t['success'] for t in state_transitions) / len(state_transitions)
return {
'tool_success_rate': success_rate,
'p99_latency_ms': p99_latency,
'transition_success_rate': transition_success
}
Trade-off:
- Add tool selection verification → Increase inference cost
- Extended status tracking → increased monitoring overhead
Layer 3: Output Quality
Definition: Does Agent output meet business requirements, is verifiable, and is acceptable?
Measurable indicators:
- Output Correctness Rate: manual/automatic verification
- User Satisfaction Score: direct feedback
- Task Completion Rate: The proportion of successfully completed tasks
- Error Recovery Rate: automatic recovery ratio
Implementation example:
def evaluate_output_quality(output_data, ground_truth):
correctness = calculate_correctness(output_data, ground_truth)
# 使用 LLM 進行主觀評分
satisfaction = llm.evaluate(output_data, prompt="Rate satisfaction 1-10")
# 檢查是否達成業務目標
completion = check_business_goal(output_data)
return {
'correctness_rate': correctness,
'satisfaction_score': satisfaction,
'completion_rate': completion
}
Trade-off:
- Improve accuracy → increase verification cost
- Increase manual review → reduce automation
Summary table of key quality indicators
| Indicator category | Indicator name | Threshold value | Collection frequency | Alarm threshold value |
|---|---|---|---|---|
| Input Quality | Completeness Rate | ≥ 80% | Daily | < 85% |
| Clarity Score | ≥ 6 | Hourly | < 6 | |
| Processing Quality | Tool Success Rate | ≥ 95% | Per Minute | < 93% |
| P99 Latency | ≤ 1s | per minute | > 2s | |
| State Transition Success | ≥ 98% | Hourly | < 95% | |
| Output Quality | Correctness Rate | ≥ 90% | Daily | < 80% |
| Satisfaction Score | ≥ 7 | Hourly | < 6 | |
| Completion Rate | ≥ 95% | Hourly | < 90% |
Measurable indicator implementation mode
Mode 1: Latency distribution tracking
Scenario: Long-running Agent tasks need to ensure that P95/P99 latency does not spike.
Implementation:
from prometheus_client import Counter, Histogram
tool_latency = Histogram(
'agent_tool_latency_seconds',
'Agent tool call latency',
['tool_name', 'status']
)
tool_calls = Counter(
'agent_tool_calls_total',
'Total tool calls',
['tool_name', 'status']
)
# 記錄每次調用
with tool_latency.labels(tool_name='get_weather', status='success').time():
result = get_weather(location)
tool_calls.labels(tool_name='get_weather', status='success').inc()
# 查詢 P95
p95_latency = tool_latency.labels(tool_name='get_weather').percentile(95)
Trade-off:
- Refined grouping → more accurate diagnosis, but increases indicator overhead
- Reduce collection frequency → reduce monitoring overhead, but may delay problem detection
Mode 2: Cost Tracking and ROI Measurement
Scenario: API cost per request needs to be compared to business value.
Implementation:
def calculate_cost_per_task(task_id):
# API 成本
api_cost = get_api_costs(task_id)
# 人力成本節省
labor_saving = estimate_labor_saving(task_id)
# ROI 計算
roi = (labor_saving - api_cost) / api_cost
return {
'api_cost_usd': api_cost,
'labor_saving_usd': labor_saving,
'roi': roi,
'break_even_tasks': api_cost / labor_saving_per_task
}
Threshold:
- ROI < 1.0 → Deactivate now
- ROI < 1.5 → Re-evaluate
- ROI ≥ 2.0 → Expand deployment
Trade-off:
- Added detailed cost tracking → more accurate ROI, but increased overhead
- Use rough estimates → reduce overhead, but inaccurate ROI measurements
Mode 3: Error Classification and Root Cause Analysis
Scenario: Ensure errors are not repeated and track trends in error types.
Implementation:
class ErrorClassifier:
def classify(self, error):
# 使用 LLM 分類錯誤
classification = llm.classify(error, prompt="Classify error type: input, tool, reasoning, output")
# 追蹤錯誤模式
self.track_error_pattern(classification, error)
return classification
error_stats = {
'input_errors': 12,
'tool_errors': 45,
'reasoning_errors': 8,
'output_errors': 3
}
Trade-off:
- Increase error classification granularity → more accurate root cause analysis, but increases inference cost
- Consolidate error categories → Reduce cost, but reduce diagnostic capabilities
Actual deployment boundaries and limitations
Boundary 1: Threshold for input preprocessing
Question: When the input is incomplete or unclear, should we reject it or try to supplement it?
Decision Boundary:
- Supplementary Strategy: Applicable to scenarios where “necessary information is insufficient” but “can be safely supplemented”
- Threshold: Supplementary success rate ≥ 95%
- Rejection Policy: Applicable to scenarios where “necessary information is missing” and “cannot be safely supplemented”
- Threshold: Supplementary success rate < 80%
Implementation:
def should_supplement_input(input_data):
required_fields = get_required_fields(input_data)
missing = required_fields - input_data.keys()
if not missing:
return False
# 評估補充可能性
supplementability = evaluate_supplementability(missing, input_data)
return supplementability >= 0.95
Boundary 2: Recovery strategy for tool invocation failure
Question: When a tool call fails, should it be retried, rolled back, or terminated?
Decision Boundary:
- Retry Strategy: Applicable to “temporary failure” and “safe to retry”
- Threshold: Retry success rate ≥ 90%
- Fallback Strategy: Applicable to “replaceable tools”
- Threshold: replacement success rate ≥ 95%
- Termination Strategy: Applicable to “permanent failure” or “too high risk”
- Threshold: No alternatives or unacceptable risk
Implementation:
def handle_tool_failure(tool_call):
error_type = classify_error(tool_call['error'])
if error_type == 'temporary':
retries = 3
success = try_retries(tool_call, retries)
return success if success else fallback()
elif error_type == 'recoverable':
fallback_tool = find_alternative(tool_call['tool'])
return execute_tool(fallback_tool)
else: # permanent or high-risk
terminate_task()
notify_user()
Boundary 3: Balance between monitoring overhead and business value
Question: How much more detailed monitoring will increase the cost?
Calculation:
def calculate_monitoring_overhead():
# 每次請求的監控開銷
monitoring_cost_per_request = (
sampling_rate * sampling_cost +
metric_aggregation_cost * aggregation_interval +
alerting_cost * alert_threshold
)
# 對比業務價值
value_per_request = calculate_business_value()
overhead_ratio = monitoring_cost_per_request / value_per_request
return overhead_ratio
Threshold:
- Overhead Ratio < 10% → Acceptable
- Overhead Ratio ≥ 20% → Re-evaluate monitoring granularity
Evaluate design principles
Principle 1: Operability first
Principle: All evaluation metrics must be operational in a production environment and cannot be limited to offline analysis.
Implementation:
# ❌ 錯誤:離線分析
def offline_evaluation():
return analyze_historical_logs()
# ✅ 正確:實時可操作
def live_evaluation():
if latency_p99 > 2000:
pause_deployment()
notify_team()
Principle 2: Make the threshold clear
Principle: Each indicator must have a clear threshold and take immediate action if it exceeds the threshold.
Implementation:
# 定義門檻
THRESHOLDS = {
'tool_success_rate': 0.95,
'p99_latency_ms': 2000,
'correctness_rate': 0.90
}
# 實時檢查
def check_thresholds(metrics):
for metric, threshold in THRESHOLDS.items():
if metrics[metric] < threshold:
action = get_action_for_threshold(metric, threshold)
action.execute()
Principle 3: Layered reporting and action
Principle: Monitoring teams at different levels see reports with different granularities.
Reporting Level:
- L1: Operation and maintenance layer - real-time indicators, threshold alarms
- L2: Technical layer - fine-grained diagnosis, root cause analysis
- L3: Business Layer - ROI indicator, business value
Implementation:
def generate_reports(metrics):
l1_report = {
'alert_status': 'active' if any(metrics < THRESHOLDS) else 'normal',
'critical_metrics': [m for m in metrics if metrics[m] < THRESHOLDS[m]]
}
l2_report = {
'root_cause': diagnose(metrics),
'recommendations': get_recommendations(metrics)
}
l3_report = {
'roi': calculate_roi(metrics),
'business_value': calculate_business_value(metrics)
}
return l1_report, l2_report, l3_report
Link measurement indicators to business value
Case: Customer Service Automation Agent
Scenario: AI Agent handles customer inquiries
Business indicators:
- Average response time: from 5 minutes to 30 seconds
- Customer Satisfaction: down from 3.2 to 4.1
- Labor costs: Reduce customer service manpower by 70%
- Throughput: increased from 50 to 300 per hour
Measurable indicators:
- Cost per request: $0.15
- Labor cost savings per request: $5.00
- ROI: 3.3x
Threshold:
- ROI < 1.0 → not worth deploying
- ROI ≥ 2.0 → scalable deployment
- ROI ≥ 3.0 → highest priority
