在用戶之前發現並修好 AI Agent 的問題
查看一次執行中的每則訊息、工具呼叫與決策,包含輸入、輸出與耗時,精確鎖定問題環節。
把反覆出現的故障歸併成 issue,附上嚴重程度、受影響用戶、最後出現時間與信心分數,取代零散告警。
由 Agent 負責調查並提供後續自動化,涵蓋 Slack、網頁端與 MCP,讓除錯發生在團隊本來就在用的地方。
在 pull request 上針對改動執行情境,並與真實流量比對,合併前攔截回歸。

Sim is the open-source AI workspace for building, deploying and governing AI agents. Create agents visually, in Chat or in code, ground them in a synced knowledge base, connect 270+ integrations, and control access, spend and deployment from one place — on Sim Cloud or self-hosted.
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
