Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langgraph-react-agent-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 writes tools with typed schemas, creates the agent with create_react_agent, sets the recursion limit and proposes a token budget. You get an agent that stops properly and does not swallow its errors, with a migration path from AgentExecutor if needed.
