Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react18-batching-fixes

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 spots setState calls inside async methods, timers or promises, then follows the decision tree before any use of flushSync. You get a targeted fix and tests that no longer rely on intermediate states.
