Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-runtime-inspection

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 connects to the running app through the agent-react-devtools CLI, inspects components, their props, state and hooks, then records a re-render profile. You get a diagnosis of a slow component or one that re-renders for no clear reason.
