Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install mongodb-query-performance-index

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 reviews a slow query or the slowest queries on the cluster, then first suggests an index or a rewritten aggregation pipeline. You get a diagnosis and precise index or pipeline recommendations.
