Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install ef-core-query-optimization

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 traces the data access code without running it, confirms bottlenecks from SQL when it is available, then cuts round-trips, duplicated rows and full scans. It favors fixes that reduce queries over micro-optimizations.
