Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install threejs-performance-tuning

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 starts by measuring render statistics, then cuts draw calls through merging, instancing or LOD and removes wasteful work from the frame loop. It also flags common mistakes such as repeated shader compile stalls.
