Replace `RUN curl -LsSf https://astral.sh/uv/install.sh | sh` across all starter Dockerfiles with `COPY --from=ghcr.io/astral-sh/uv:latest /uv /uvx /usr/local/bin/`. The curl|sh form has a pipe-swallow latent bug: when astral.sh returns a 5xx, curl fails but `sh` gets no stdin and exits 0, so the layer "succeeds" with no uv binary. A later `RUN uv sync` then crashes with `uv: not found` (exit 127). This already bit the agno starter today (run 24809910399) when astral.sh had a transient outage; upstream recovered on its own so this is latent-bug cleanup, not a hotfix. Using the official uv image is uv's own recommended pattern: it's cache-friendly, network-free at build time, and sidesteps the pipe failure mode entirely. Scope: all 20 Dockerfiles under examples/integrations/*/Dockerfile, examples/integrations/*/docker/Dockerfile.agent, and examples/showcases/scene-creator/agent/Dockerfile. Verified locally: `docker build -f docker/Dockerfile.agent ./agent` for agno succeeds against the new pattern.
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
