⚠️ Breaking Changes

  • langgraph: classify any namespaced event as child content (#844)

Upgrading to 0.0.59 (@threadplane/langgraph)

filterSubagentMessages is removed. Delete it from provideAgent(...) — it is now a compile-time error. The behavior it opted into is the default, and broader.

Child-graph output no longer reaches messages(). Any namespaced stream event — a tool-dispatched subagent (tools:<id>) or a compiled child added with add_node (research:<uuid>) — belongs to that child's stream and never merges into the parent transcript or values(). If your UI relied on child tokens appearing inline, render them from subagents() instead.

subagents() may contain more entries. Plain subgraph nodes now register there, keyed by their namespace segment and named by node. Tool-dispatched children are unchanged: keyed by tool-call id, named by subagent_type.

transcriptNodeNames is unaffected and keeps its original job — filtering top-level side-effect nodes such as routers and title generators. It was never the right lever for child graphs; that distinction is now structural.
