Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install langsmith-custom-app-development

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 uses the langsmith apps CLI to scaffold, push and replicate an app, checks its logic without a browser, then sanitizes it before sharing outside your organization. These apps belong to the Enterprise plan. You get an app ready to publish in your workspace.
