Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install structured-data-transformation

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 jq, yq and query tools to filter, transform and aggregate your JSON, YAML, TOML, CSV or Parquet files, then convert the result from one format to another. You get commands and results, with no database server needed.
