The A2UI middleware (@ag-ui/a2ui-middleware) forwards injectA2UITool on
forwardedProps; ag-ui-langgraph surfaces it into agent state at
state["ag-ui"]["inject_a2ui_tool"]. The CopilotKit LangGraph middleware
(py + js) now reads that flag and only injects generate_a2ui when it is
truthy (opt-in), drops the runtime's render_a2ui so the model sees one
A2UI tool, and skips if the agent already defines generate_a2ui. The
catalog only binds surfaces; it is no longer the gate.
Reverts the earlier runtime-forward + context-channel approach.
Deps: ag-ui-langgraph>=0.0.38 (py), @ag-ui/langgraph 0.0.37 (sdk-js),
@ag-ui/a2ui-middleware 0.0.6 + @ag-ui/langgraph 0.0.37 (runtime);
.npmrc min-release-age exclude for @ag-ui/a2ui-middleware. Showcase
langgraph pins bumped to copilotkit==0.1.94a3 / sdk-js 1.59.3-alpha.3 /
@ag-ui/langgraph 0.0.37.
Picks up per-request header forwarding (onRequest hook + headerFactory)
and the prepareStream configurable+context partition fix from
ag-ui-protocol/ag-ui#1763. Together with copilotkit==0.1.91 on the
Python side (R3a), this unblocks D6 LGP/LGT header propagation.
The mergeConfigs() change in 0.0.33 also fixes the HTTP 400 from
langgraph-api 0.7+ when both configurable and context are present.
Bumped in two files:
- packages/runtime/package.json: 0.0.31 -> 0.0.33
- packages/sdk-js/package.json: 0.0.31 -> 0.0.33
Added @ag-ui/langgraph to minimumReleaseAgeExclude in .npmrc.
pnpm-lock.yaml regenerated.
Showcase auto-redeploys on merge via showcase_build.yml.
