Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install custom-third-party-api-emulator

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 implements the provider behavior your integration uses, runs the emulator alongside the built-in services, then configures seed data and packages it. The skill requires Node 24 or later.
