Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install llm-app-security-hardening-2

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 against the OWASP Top 10 for LLMs, then adds input validation, injection detection, moderation, system prompt protection and tenant isolation. You get a hardened input pipeline and a list of controls to test.
