Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sql-cost-performance-audit

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 analyzes SQL for anti-patterns that drive warehouse bills (BigQuery, Snowflake, Redshift, Postgres): SELECT *, full scans, non-sargable predicates, Cartesian joins. It gives a health score out of 100 and a prioritized plan, with for each finding the reason, the fix and the estimated saving.
