Baseline: showcase/integrations/langgraph-python/.
This package ports the frontend-composition demos satisfied by the shared
Claude backend in src/agents/agent.py, plus dedicated ogui / headless
surfaces. The demos below are deliberately out of scope for this pass and
left for a follow-up.
byoc-json-render — dedicated /byoc-json-render agent endpoint emits
a JSON spec; frontend renders via <JSONUIProvider> + <Renderer />
against a Zod catalog (MetricCard, BarChart, PieChart). Includes the
<JSONUIProvider> fix from PR #4271 and the defineRegistry
children-forwarding fix for MetricCard.byoc-hashbrown — dedicated /byoc-hashbrown agent endpoint emits
the hashbrown JSON envelope {ui: [{metric: {props: {...}}}, ...]}
(NOT XML — the #4271 fix). Frontend parses via useJsonParser +
useUiKit with MetricCard / PieChart / BarChart / DealCard / Markdown.multimodal — dedicated /multimodal agent endpoint with
convert_part_for_claude that translates AG-UI image / document
parts into Claude's native Messages API shape. PDFs flatten to text
via pypdf. No legacy-binary shim required — that shim is
specific to the @ag-ui/[email protected] converter and is not needed
when HttpAgent forwards modern parts to the Claude Agent SDK backend.voice — dedicated /api/copilotkit-voice runtime with a
GuardedOpenAITranscriptionService that reports a typed 401 when
OPENAI_API_KEY is missing (vs a silent 503). Transcription service
is written onto the V2 runtime instance directly to work around the
V1 wrapper silently dropping the service. Backend reuses the shared
Claude agent.agent-config — dedicated /agent-config agent endpoint that reads
tone / expertise / responseLength off
forwarded_props.config.configurable.properties and builds the
system prompt per turn. Frontend route subclasses HttpAgent to
repack provider properties into the nested configurable shape so
the wire format matches the langgraph-python reference exactly.auth — dedicated /api/copilotkit-auth route uses
createCopilotRuntimeHandler from @copilotkit/runtime/v2 directly
so the onRequest hook actually fires (V1 adapter drops hooks).
Bearer-token gate returns 401 on mismatch. Includes the #4271
defaults fix: useDemoAuth defaults to signed-in, plus
ChatErrorBoundary so the page never white-screens on auth
transitions.cli-start — manifest-only entry with the framework-slug init command.prebuilt-sidebar — default <CopilotSidebar /> against the shared agent.prebuilt-popup — default <CopilotPopup /> against the shared agent.chat-slots — custom welcomeScreen, input.disclaimer, messageView.assistantMessage slots.chat-customization-css — scoped CSS variable and class overrides.headless-simple — useAgent + useComponent minimal custom chat surface.frontend-tools — useFrontendTool with sync handler (change_background).frontend-tools-async — useFrontendTool with async handler (query_notes).hitl-in-app — async useFrontendTool HITL; fixed inset-0 overlay
(not createPortal) to avoid pulling in @types/react-dom.readonly-state-agent-context — useAgentContext read-only context.tool-rendering-default-catchall — zero-renderer built-in default.tool-rendering-custom-catchall — useDefaultRenderTool wildcard.open-gen-ui — minimal open-ended generative UI (dedicated
/api/copilotkit-ogui route with openGenerativeUI flag).open-gen-ui-advanced — OGUI with frontend sandbox functions
(evaluateExpression, notifyHost).headless-complete — full custom chat surface built on useAgent,
with per-tool renderers, frontend component, and wildcard catch-all.
Points to the shared /api/copilotkit route (the reference points at
/api/copilotkit-mcp-apps; this package doesn't port mcp-apps — the
Excalidraw-MCP suggestion will surface as a catch-all tool card).gen-ui-interrupt — relies on langgraph's interrupt() primitive that
pauses the graph and resumes on a client-side response. Claude Agent SDK
does not expose an equivalent graph-interrupt API.interrupt-headless — same reason; this is a headless surface for
resolving a langgraph interrupt.agentic-chat-reasoning, reasoning-default-render,
tool-rendering-reasoning-chain — require streaming Claude extended-
thinking (reasoning) blocks as distinct AG-UI message parts. The current
src/agents/agent.py AG-UI bridge does not translate Anthropic
thinking content blocks; adding it correctly requires new event types
and a thinking-aware message buffer. Follow-up.These are feasible on this package but each pulls in substantial multi-file frontend infrastructure (catalogs, renderers, MCP client glue, theme pipelines) that did not fit this pass. Left for dedicated follow-up commits.
declarative-gen-ui — A2UI BYOC catalog (Card/StatusBadge/Metric/
InfoRow/PrimaryButton) wired via a2ui.catalog on the provider.a2ui-fixed-schema — fixed-schema A2UI with two JSON schemas
(flights + booked) and a per-demo catalog.mcp-apps — MCP server-driven UI via activity renderers. Claude Agent
SDK supports MCP clients, but the langgraph-python reference relies on
CopilotKit runtime wiring through a dedicated
/api/copilotkit-mcp-apps/route.ts plus agent-side MCP client glue.beautiful-chat — 28+ supporting files (layout, canvas, generative UI
charts, hooks, theme CSS, showcase config, A2UI catalog). Porting
requires significant surface-area review that did not fit this pass.agent.py (unlocks
agentic-chat-reasoning, reasoning-default-render,
tool-rendering-reasoning-chain).declarative-gen-ui, a2ui-fixed-schema).mcp-apps).
