Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install api-contract-drift-detector

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 checks C# controllers and DTOs against the calls made by React, Angular, Vue or HTTP clients, and flags removed keys, added required parameters or changed status codes. It also flags fields the clients send that the backend no longer reads.
