Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install bigquery-custom-functions

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 picks the lightest function type (SQL, JavaScript, managed Python or a remote function on Cloud Run), sets up permissions and connections, writes the function from a template, then validates and cleans it up if needed. It also explains how to install PyPI libraries and call an external API.
