Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install frontend-backend-auth-flow

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 walks through login, token storage and sending, refresh and 401 error handling, then flags mismatches between the two sides. You get a list of inconsistencies to fix. This is not a security audit.
