The smoke build path (docker/Dockerfile.agent) runs `uv sync` against
agent/pyproject.toml + agent/uv.lock, but those still pinned
ag-ui-langgraph==0.0.34 (and the lock still pinned copilotkit==0.1.87).
copilotkit 0.1.93 requires ag-ui-langgraph[fastapi]>=0.0.35, so uv sync
failed with "No solution found" and the langgraph-fastapi smoke job went
red. The prior fix only bumped the production Dockerfile's
`uv pip install`, which the smoke path does not use.
Bump pyproject to ag-ui-langgraph[fastapi]==0.0.37 and regenerate uv.lock
(copilotkit 0.1.87->0.1.93, ag-ui-langgraph 0.0.34->0.0.37). Verified by
building docker/Dockerfile.agent locally: uv sync now resolves and the
agent boots ("Uvicorn running on 0.0.0.0:8123" / "Application startup
complete") serving HTTP 200 on /health.
Also reconcile parity: strands-python's entrypoint.sh legitimately diverges
from the langgraph-python north-star (it boots the strands agent via
`uv run python main.py` and serves Next via `next start`, not serve.py +
standalone server.js). Add entrypoint.sh to strands-python's
allowedDivergence, mirroring how langgraph-js already declares its own
custom entrypoint. parity:check now reports 0 errors.
CopilotKit <> LangGraph Starter
This is a starter template for building AI agents using LangGraph and CopilotKit. It provides a modern Next.js application with an integrated LangGraph agent to be built on top of.
Prerequisites
- Node.js 18+
- Python 3.8+
- Poetry 2+
- Any of the following package managers:
- OpenAI API Key (for the LangGraph agent)
Getting Started
- Install dependencies using your preferred package manager:
# Using npm (default)
npm install
# Using pnpm
pnpm install
# Using yarn
yarn install
# Using bun
bun install
- Install Python dependencies for the LangGraph agent:
# Using npm (default)
npm run install:agent
# Using pnpm
pnpm install:agent
# Using yarn
yarn install:agent
# Using bun
bun run install:agent
- Set up your OpenAI API key:
echo 'OPENAI_API_KEY=your-openai-api-key-here' > agent/.env
- Start the development server:
# Using npm (default)
npm run dev
# Using pnpm
pnpm dev
# Using yarn
yarn dev
# Using bun
bun run dev
This will start both the UI and agent servers concurrently.
Available Scripts
The following scripts can also be run using your preferred package manager:
dev- Starts both UI and agent servers in development modedev:debug- Starts development servers with debug logging enableddev:ui- Starts only the Next.js UI serverdev:agent- Starts only the LangGraph agent serverbuild- Builds the Next.js application for productionstart- Starts the production serverinstall:agent- Installs Python dependencies for the agent
Documentation
The main UI component is in src/app/page.tsx. You can:
- Modify the theme colors and styling
- Add new frontend actions
- Customize the CopilotKit sidebar appearance

Troubleshooting
Agent Connection Issues
If you see "I'm having trouble connecting to my tools", make sure:
- The LangGraph agent is running on port 8000
- Your OpenAI API key is set correctly
- Both servers started successfully
Python Dependencies
If you encounter Python import errors:
cd agent
poetry lock && poetry install
