Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install browser-cpu-profiling

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 the built-in browser profiler during the slow action, captures call stacks and timings, then suggests optimizations. You get the most expensive functions and ideas to lighten them.
