Install with the CLI

In a terminal, from the folder you want:

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

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 sets out the AI threat model, puts guardrails in place (NeMo Guardrails), filters outputs and scrubs personal data, then secures the endpoints and model weights. You get a list of controls and configurations to adapt.
