Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sinatra-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 reviews a Sinatra application: it enables Rack::Protection and CSRF protection, prevents SQL injection with parameterized queries and XSS in templates. It also supports security reviews.
