AccumulatorTransform now forwards a { ui } object chunk to the stream consumer
and keeps it out of the accumulated text answer, so widgets reach callers via
AgentSquad.routeRequest — not only when driving the agent directly. A stream
with no widget chunk is byte-identical to before; object chunks (e.g. thinking)
already flowed through this transform. Docs updated.
Closes #598

Summary
Makes
AgentSquad.routeRequestforward aGroundedAgent{ ui }widget chunk to the caller instead of dropping it. Previously the orchestrator'sAccumulatorTransformforwarded only text, so widgets worked only when consuming the agent directly — a usability gap and a divergence from Python (whose orchestrator forwards the chunk unchanged).Stacked on #597 (base
feat/typescript-mcp-tool-ui) to keep the TS stack linear and update both docs notes without conflict. Merge order: #591 → #593 → #597 → this.Changes
AccumulatorTransform._transform: a{ ui }object chunk is pushed downstream and returns early — never added to the text accumulator, so the saved assistant text stays clean.User experience
Streaming via
orchestrator.routeRequest, the caller now receives the{ ui }widget chunk interleaved with text-string chunks (check each chunk's type) — matching how Python delivers it.Checklist
