Same extraction as langgraph-python across the nine starters whose runtime
route builds a generic HttpAgent (adk, agno, claude-sdk-python,
claude-sdk-typescript, crewai-flows, ms-agent-framework-dotnet,
ms-agent-framework-python, pydantic-ai, strands-python). Each starter's
route now imports createDefaultAgent() from a new src/agent.ts instead of
constructing HttpAgent inline; the URL fallback/normalisation logic is
preserved verbatim per starter (identical bodies for four, agno's "/agui"
suffix, claude-sdk-*'s trailing-slash strip, crewai-flows' bare strip,
strands-python's second STRANDS_AGENT_URL fallback).
Each starter also gets channel-host.mts (copied verbatim from
langgraph-python) and its own tsconfig.channel.json, needed because the
starters' shared allowJs:true tsconfig makes tsx's resolver prefer a stray
index.ts the published fast-json-patch package ships without its source,
which otherwise crashes the channel script before it runs. package.json
gains the channel/typecheck:channel scripts and three deps: dotenv,
@copilotkit/channels (pinned to the same 1785633429 canary build as the
other @copilotkit/* packages), and tsx as a devDependency. This canary pin
is a temporary workaround pending a stable release with identifyUser
support, and must move before this path ships to users.
ms-agent-framework-dotnet's postinstall (a .NET SDK probe) fails on
machines without the SDK installed; dependency resolution itself succeeds
and is unaffected. crewai-flows, pydantic-ai, and strands-python each carry
a small number of pre-existing, unrelated tsc --noEmit errors (JSX/recharts
typing clashes and a missing exported type) not touched by this change.
CodeRabbit flagged that the form onSubmit added to headless-chat could submit
empty/whitespace messages. The handler now returns early on blank input and the
submit button is disabled when the message is empty. Applied to the claude-sdk
starters (where the form lives); headless-chat.tsx is already declared
allowedDivergence for these instances, so parity stays green.

Resolve the real issues surfaced by CodeRabbit on the new claude-sdk-python /
claude-sdk-typescript starters (frontend files are shared, so most fixes apply
to both):
- Fix two type errors that `ignoreBuildErrors` was masking: `JSX.IntrinsicElements`
-> `React.JSX.IntrinsicElements` (@types/react 19) and the Recharts `<Bar shape>`
callback type; then drop the blanket `typescript.ignoreBuildErrors` from
next.config.ts so source type-checks. The Dockerfile's build-time patch still
re-adds it for the `next@latest` Docker build, so deploy behavior is unchanged.
- Fix Tailwind v4 CSS-variable syntax: `bg-[--x]` -> `bg-[var(--x)]`, and
`border-3` -> `border-[3px]` (border-3 is not a utility -> invisible spinner).
- Harden the agent tools: omit the empty ANTHROPIC_API_KEY, wrap the Anthropic
call in try/catch (TS + Python), normalize the AGENT_URL trailing slash, and
make the Flight schema's id/airlineLogo/statusIcon required to match the
"must have" tool description.
- Minor a11y: mode-toggle `aria-pressed`/`type`/`role`, headless-chat `<form>`
+ `aria-label` (Enter-to-submit).

Two clonable starter templates showing CopilotKit driving a Claude Agent SDK
agent over AG-UI, mirroring the langgraph-python showcase (todos canvas, charts,
flight cards, dynamic dashboards, HITL, theme, threads drawer).
Each agent is a thin, idiomatic layer on the official ag-ui-claude-sdk /
@ag-ui/claude-agent-sdk adapters: three backend tools (query_data, search_flights,
generate_a2ui) live in per-tool modules and are wired into ClaudeAgentAdapter,
while the shared todo board is driven by the adapter's built-in ag_ui_update_state
tool. The default model is claude-sonnet-5 and local dev uses a real
ANTHROPIC_API_KEY (matching the official AG-UI dojo). Both instances are
registered in the _parity manifest so their frontends stay synced with the
langgraph-python north-star.
