Apache SkyWalking AI Sessionizer — LangChain plugin

Records what each of a LangChain or LangGraph agent's tool calls changed on disk, so a conversation shows the work as well as the words.

It is the smaller half of a pair: asz-changes does the scanning and the diffing, and this says when a tool call begins and ends, which LangChain has no way to say on its own. The application imports nothing.

pip install apache-skywalking-asz-langchain
asz-langchain enable

export ASZ_CHANGES=true
export ASZ_WATCH=/path/to/the/workspace
export ASZ_CHANGES_DATA=/var/lib/asz/changes

Full setup, what it costs and what it cannot see

To collect the conversation itself, which needs no plugin at all, see LangChain and LangGraph.
