Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install automated-performance-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 records performance traces from the command line, analyzes them with the xcprof tool and attributes costs to your app's code. For each measurement family it states whether it could be measured, so it never claims results it did not obtain. You get a report of what to fix.
