Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install web-security-implementation

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 reviews your application's entry points, applies validation and sanitization, secures authentication (password hashing, rate limiting) and protects against CSRF. You get concrete fixes and a checklist.
