Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install browser-extension-developmentWith 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 loginThe agent structures an extension: V3 manifest, content scripts, messages between parts, storage, injected interface and permissions. It also reminds you of the Chrome Web Store publishing constraints.
