Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install nodejs-security-assessment

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

This skill is for authorized security assessments of Node.js and Express applications. Before any test, the agent asks for the target, written authorization and scope. It then works through phases: fingerprinting, prototype pollution detection and parameter injection, using non-destructive tests.
