Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install spa-hidden-api-discovery

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 finds the backend API of a single-page app from its HTML shell and public JavaScript bundles, then tests the routes found for broken access control. Tests start only after the authorized scope is confirmed.
