Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install template-injection-testing

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 starts with non-destructive detection probes, identifies the template engine, and moves to more active payloads only after the scope is confirmed. It reviews template fields such as email or documentation editors. You get findings to validate with the owner.
