Blog: capture and replay LangChain and LangGraph conversations - #935

Conversation
The third post on Apache SkyWalking AI Sessionizer. It builds a small LangGraph triage agent on Amazon Bedrock - a supervisor, an analyst sub-agent, a summarising tool and a tool that writes a report - points its tracing client at Sessionizer 0.5.0 with four environment variables, and replays the conversation locally and in SkyWalking. Every screenshot is from one real run of the post's own code: the analyst's child stream, the request a model call was sent rebuilt byte for byte, the report the agent wrote as a recorded file change, and the conversation in Horizon under the LangChain runtime.

The third AI Sessionizer post, for the 0.5.0 release: capturing and replaying conversations from an agent you build with LangChain or LangGraph, where the first two covered Claude Code.
It builds a small LangGraph triage agent on Amazon Bedrock (a supervisor, an analyst sub-agent, a summarising tool, and a tool that writes a report), points its tracing client at Sessionizer with four environment variables, and replays what happened: the sub-agent's own stream, what each model call was sent, what each tool changed on disk, and the same conversation in SkyWalking.
Every screenshot is from one real run of the code printed in the post, on Sessionizer 0.5.0. The two diagrams are SVG.
The install commands assume 0.5.0 is published, so this should merge once the release is announced.
