Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install behavior-preserving-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 assesses the risk of the change, measures the starting state, finds the main bottleneck, applies a safe optimization, then compares before and after. It documents a rollback plan. You get a measured improvement and tests that still pass.
