AgentKit

Install @inngest/agent-kit and inngest with your package manager; for a new project, create a directory and initialize it first.

In index.ts, define an agent with createAgent, including its name, description, system prompt, and model. Set ANTHROPIC_API_KEY as an environment variable.

Create a server with createServer({ agents: [agent] }) and call server.listen(3000, ...).

Run the file with the command below, then start the Inngest dev server pointing to http://localhost:3000/api/inngest using the command below.

npx tsx ./index.ts

npx inngest-cli@latest dev -u http://localhost:3000/api/inngest

Open the dev server’s functions page, invoke the agent function with an input prompt, and inspect the run output.

Add a save_answer tool to each agent that writes its answer into the shared network state under a distinct key.

Create a network with createNetwork, include both agents, define the shared state type, and configure a router that calls the security agent first, the database administrator next, and then ends the network.

Register both agents and the network with createServer.

With the Inngest dev server running, invoke the network function from its functions page using the documented JSON input format, then inspect the finalization step’s JSON payload.
