Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install modern-web-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 searches its guides for the use case, retrieves the matching recommendations and checks that the code follows them. It also notes browser support limits and the fallbacks to use.
