Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install ag-ui-protocol-backend

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent helps you write a backend that implements AbstractAgent.run() and streams AG-UI events over SSE, then tune state sync, tool calls and human approvals. You get a protocol-compliant backend base and pointers for debugging event flows.
