Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langgraph-streaming-setup

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 chooses the stream mode that fits your interface, configures an SSE or WebSocket endpoint without proxy buffering, then filters events before they reach the browser. You get a streaming endpoint and a checklist before production.
