Good. I have all the information I need. Our project already has custom-built observability (metrics collector, stats snapshots, cost tracking, drift detector), but hasn’t explored the broader ecosystem of dedicated AI agent observability platforms. This is a high-value comparison topic.
Now let me compose the report.

AI Agent 可觀測性工具生態——Langfuse、LangSmith、AgentOps 與我們的自建方案比較
直接可改善專案的可觀測性和成本管控能力,且有潛力寫成部落格文章(「自建 vs 外掛——AI Agent 可觀測性的抉擇」)。

Now I have enough data to compile the report. Let me also check for overlap with existing articles.
There’s an existing article ai-agent-as-a-service-business-models-2026-02-24.md covering AI Agent subscription business models broadly, but not specifically about trading signal services with concrete win rate data and pricing tiers. The angle is distinct.
Now I have all the material I need. Let me summarize what I’ve found:
Existing coverage (4 articles touching memory):
03-02: Two articles on engineering tiers (ephemeral/session/persistent) and default-to-forgetting
02-23: Memory/tools/planning architecture intro
03-03: FTS5 + hybrid search (sqlite-vec)
Unique angle from explorer’s report: The cognitive science three-memory taxonomy (episodic/semantic/procedural) as a diagnostic lens for our system. This reveals a specific gap: we have strong semantic + procedural memory, but almost zero episodic memory.
