The marked block that wires managed Intelligence is the region a hosted reader copies verbatim, and nothing checked it. Both gaps were deliberate: the parity manifest lists `src/app/api/copilotkit/**` under `allowedDivergence` for every instance it tracks, and no `docker-compose.test.yml` sets `COPILOTKIT_LICENSE_TOKEN`, so every smoke-tested starter takes the else arm and the `intelligence:` arm has never run in CI. The cost was already visible. The block's code was byte-identical in 21 of 22 starters, but its warning comment had drifted into five variants and the two `ms-agent-framework-*` starters shipped the `demo-user` stub with no warning at all. That drift is how the localhost default of OSS-981 survived in all 22 copies at once. Add `scripts/validate-intelligence-wiring-block.ts`, which greps the opening marker, compares every site against the north-star starter, and fails on the first line that differs. Two normalisations keep it usable: the block is dedented, because `agentcore` nests it deeper, and the else arm's runner name is masked, because `agentcore` runs `AgentCoreRunner` in front of a Bedrock session where an in-process runner has nothing to run. Everything else, comment text included, must match to the byte. Then unify the warning at all 22 sites on the fullest wording, which also says the id must exist in Intelligence or thread operations can fail. The check passes on day one, so it is a ratchet rather than a migration. It is a shape gate, not a content gate: 22 identically wrong copies still pass. What it guarantees is that a fix reaches all of them or none. Not covered: enrolling the `intelligence:` arm in the smoke path. That needs a license token in CI and a reachable endpoint from the compose network, and is tracked separately.
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
