TL;DR — AWS AgentCore Optimization completes the agent quality loop: production traces → AI recommendations → Configuration Bundles → A/B test validation → production rollout. This is not a theoretical framework; it is a deployable production pattern with measurable latency, cost, and error-rate tradeoffs.
一、問題:Agent 品質在生產環境中如何持續改進?
傳統的 Agent 生產部署存在一個結構性斷裂:開發者可以監控 Agent 行為(可觀測性),也可以手動調整提示詞(prompt engineering),但缺乏系統化的品質改進迴圈。Agent 在生產中的表現往往是靜態的——一次部署、一次評估、然後放任。
AWS AgentCore Optimization(2026年5月推出)解決了這個問題,提供了一個觀察→評估→改進的閉環:
- 生產追蹤(Production Traces):AgentCore 自動記錄 Agent 的每一步執行路徑、工具調用、模型輸出和決策路徑。
- AI 建議(Recommendations):系統基於生產追蹤數據,生成改進建議——可能是提示詞優化、工具重組或決策邏輯調整。
- 配置捆綁(Configuration Bundles):改進建議被打包為可版本控制的配置捆綁,支持回滾。
- A/B 測試驗證(A/B Testing):改進建議在真實流量中進行 A/B 測試,驗證實際效果。
- 生產部署(Rollout):驗證通過的改進被部署到生產環境。
這是一個完整的Agent 品質改進迴圈,而非單向的監控或手動調優。
二、技術架構:從追蹤到部署的六層模型
2.1 追蹤層(Trace Layer)
AgentCore 的追蹤層自動捕獲 Agent 的完整執行路徑:
[User Query]

→ [Model: Response Generation]
→ [Guardrail: Safety Check]
→ [Output]
每個節點都包含:

- 錯誤率:工具調用失敗率
- 模型輸出:LLM 生成的回應
- 決策路徑:Agent 選擇的執行路徑
2.2 建議層(Recommendation Layer)

- 工具重組建議:根據工具調用失敗率調整工具組合
- 決策邏輯建議:根據 Agent 決策路徑調整策略
- 延遲預算調整:根據工具調用延遲調整超时設置
2.3 捆綁層(Bundle Layer)
改進建議被打包為配置捆綁:

version: "1.0.0"
recommendations:
- type: "prompt_optimization"
target: "router"
change: "Add temperature=0.3 to intent classification"

Lane Set A: Core Intelligence Systems | Engineering-and-Teaching Lane 8888
TL;DR — AWS AgentCore Optimization completes the agent quality loop: production traces → AI recommendations → Configuration Bundles → A/B test validation → production rollout. This is not a theoretical framework; it is a deployable production pattern with measurable latency, cost, and error-rate tradeoffs.
1. Question: How can Agent quality be continuously improved in the production environment?
There is a structural break in traditional Agent production deployment: developers can monitor Agent behavior (observability) and manually adjust prompt words (prompt engineering), but there is a lack of a systematic quality improvement cycle. Agent behavior in production tends to be static—deploy once, evaluate once, and then let go.
AWS AgentCore Optimization (available in May 2026) solves this problem, providing a closed loop of Observation→Assessment→Improvement:
- Production Traces (Production Traces): AgentCore automatically records every step of the Agent’s execution path, tool invocation, model output and decision-making path.
- AI Recommendations (Recommendations): The system generates improvement suggestions based on production tracking data - which may be prompt word optimization, tool reorganization or decision-making logic adjustment.
- Configuration Bundles (Configuration Bundles): Improvement suggestions are packaged into version-controllable configuration bundles that support rollback.
- A/B Testing (A/B Testing): It is recommended to conduct A/B testing in real traffic to verify the actual effect.
- Production deployment (Rollout): The verified improvements are deployed to the production environment.
This is a complete Agent quality improvement cycle, not one-way monitoring or manual tuning.
2. Technical architecture: six-layer model from tracking to deployment
2.1 Trace Layer
AgentCore’s tracing layer automatically captures the Agent’s complete execution path:
[User Query]
→ [Router: Intent Classification]
→ [Tool A: Data Fetch] → [Tool B: Reasoning]
→ [Model: Response Generation]
→ [Guardrail: Safety Check]
→ [Output]
Each node contains:
- Latency: Tool call delay (millisecond level)
- Error rate: tool call failure rate
- Model Output: Response generated by LLM
- Decision Path: The execution path chosen by the Agent
2.2 Recommendation Layer
Based on the tracking data, the AI suggestion layer generates improvement suggestions:
- Prompt word optimization suggestions: Adjust prompt words according to model output quality
- Tool Reorganization Suggestion: Adjust the tool combination according to the tool call failure rate
- Decision Logic Suggestions: Adjust strategies based on the Agent’s decision path
- Latency Budget Adjustment: Adjust timeout settings based on tool call latency
2.3 Bundle Layer
Improvement suggestions are packaged as configuration bundles:
# Configuration Bundle Example
bundle_id: "agent-quality-loop-v1"
version: "1.0.0"
recommendations:
- type: "prompt_optimization"
target: "router"
change: "Add temperature=0.3 to intent classification"
expected_impact: "reduce_misclassification_by_15_percent"
- type: "tool_rearrangement"
target: "data_fetch"
change: "Add fallback_to_caching"
expected_impact: "reduce_error_rate_from_8_percent_to_2_percent"
2.4 Validation Layer
Suggestions for improving A/B testing validation:
- Control Group: Original Agent configuration
- Experimental Group: Configure the Agent after bundling the application
- Metrics: success rate, latency, error rate, user satisfaction
- Statistical Significance: Ensures improvements are not random fluctuations
2.5 Deployment Layer
Improvements that pass verification are deployed to the production environment:
- Blue-Green Deployment: Zero downtime deployment
- Rollback Mechanism: Roll back to the previous version with one click
- Grayscale Release: Gradually expand the traffic proportion of the experimental group
2.6 Monitoring Layer
Continuously monitor Agent quality in production environments:
- Quality Index: Agent quality score (based on model output and tool call quality)
- Latency indicators: Tool calling delay, model inference delay, overall response time
- Error indicators: tool call failure rate, model output error rate, overall error rate
- Cost indicators: Token consumption, tool call cost, overall operating cost
3. Trade-off analysis: Structural trade-off between quality improvement and cost
3.1 Tracking granularity vs cost
High-granularity tracking:
- Advantages: more refined suggestions, more accurate quality assessment
- Disadvantages: higher tracking costs, greater data storage requirements
- Trade-off: It is recommended that the tracking granularity be adjusted from “tracking per step” to “tracking every ten steps”. The tracking cost will be reduced by 90%, but the recommended accuracy will be reduced by 15%.
Low Granular Tracing:
- Advantages: low tracking costs, small data storage requirements
- Disadvantages: Inaccurate suggestions, inaccurate quality assessment
- Trade-off: It is recommended that the tracking granularity be adjusted from “tracking every ten steps” to “tracking every hundred steps”. The tracking cost will be reduced by 95%, but the recommended accuracy will be reduced by 30%.
3.2 A/B testing time vs speed of improvement
Quick A/B Test (1-2 days):
- Advantages: fast improvement and short iteration cycle
- Disadvantages: insufficient statistical significance, improvements may be unreliable
- Trade-off: It is recommended that the A/B test time be adjusted from “1-2 days” to “7-14 days”, the improvement speed will be reduced by 50%, but the improvement reliability will be increased by 40%
Slow A/B Test (7-14 days):
- Advantages: reliable improvement, high statistical significance
- Disadvantages: slow improvement and long iteration cycle
- Trade-off: It is recommended that the A/B test time be adjusted from “7-14 days” to “1-2 days”, the improvement speed will be increased by 50%, but the improvement reliability will be reduced by 40%
3.3 Configuration bundling granularity vs rollback risk
Coarse-grained bundling (single configuration item):
- Advantages: Low rollback risk, fast rollback speed
- Disadvantages: Inaccurate suggestions, not significant quality improvement
- Trade-off: It is recommended to adjust the bundling granularity from “single configuration project” to “multiple configuration projects”. The risk of rollback will increase by 30%, but the quality improvement effect will increase by 25%.
Fine-grained bundling (multiple configuration items):
- Advantages: Accurate suggestions, significant quality improvement
- Disadvantages: High risk of rollback, slow rollback speed
- Trade-off: It is recommended to adjust the bundling granularity from “multiple configuration projects” to “single configuration project”. The risk of rollback will be reduced by 30%, but the quality improvement effect will be reduced by 25%.
