Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install react-effect-best-practices

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 reviews your effects, derived state and data fetching, and flags those that can be removed. For each case you get the recommended alternative, based on the official React documentation.
