Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install nginx-module-performance

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 optimises an nginx C module against 43 rules: zero-copy buffers and I/O, connection handling, atomic locks, timeout and retry strategy and response caching. It notes the gain and the risk of each change. You get a faster module that copes better with failures.
