Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install columnar-analytics-duckdb-clickhouse

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 explains why column storage speeds up aggregates, compares DuckDB and ClickHouse, then advises on file formats, partitioning and sort keys. You get a justified engine choice and ways to speed up your queries.
