Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install shiny-r-performance-fixes

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 spots bad patterns in the code, measures what slows the app down, then applies the cheapest fixes first: remove unneeded work, reuse results, then speed up the remaining computation. You get a faster app with its logic intact.
