Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install power-query-m-transformations

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 writes the query steps, checks folding to the source and proposes suitable error handling. You get readable, efficient M code.
