@langchain/langgraph-api@1.2.1 (pulled transitively by langgraph-cli) imports
STREAM_EVENTS_V3_MODES from @langchain/langgraph/web, which only exists in
1.3.0. The starter's overrides + agent dep were pinning langgraph to 1.2.9,
causing the agent container to crash on startup with a SyntaxError. Bump
the override and the direct pin to 1.3.0, and pin @langchain/langgraph-cli
in the npx invocations so future cross-package drift in the LangChain
ecosystem cannot silently re-break this starter.

Align langgraph-js with examples/integrations/langgraph-python via the
parity tooling. Remove legacy app/ layout, adopt src/ layout, rewrite
the TS agent to expose the tracked tool surface (manage_todos,
get_todos, query_data, generate_a2ui, search_flights) and todos state,
and write the canonical PROMPT.md. Keeps LangGraphAgent + stategraph
runtime (allowed divergence per the manifest); brings deps,
Dockerfile.app, entrypoint, showcase metadata, and shared UI into
lockstep. Parity verifier: 88 ok / 0 error.
- chmod +x all new .sh scripts so they work on Linux/macOS
- Use --ignore-scripts in langgraph-js Dockerfiles to avoid postinstall
failure (agent/ dir not yet copied during npm install stage)
- Install agent deps in production Dockerfile after COPY agent/
- Fix hardcoded pnpm commands in agent-spec README
Flatten langgraph-python, langgraph-js, and mcp-apps starters so
npm install && npm run dev works out of the box. Replace Turborepo
with concurrently, move apps/* to root, update Dockerfiles, READMEs,
and entrypoints. Also remove stray pnpm-lock.yaml from a2a-a2ui and
ms-agent-framework-dotnet starters.
