Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install cluster-memory-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 finds where arrangements sit in memory, picks the right lever (index strategy, GROUP SIZE hints, slimmer views, subquery decorrelation), then checks each change with a measurement. It also prepares the final right-sizing of the replica.
