Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install oauth-redirect-local-dev

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 fixes redirect errors such as redirect_uri_mismatch or a rejected domain by choosing a valid domain with --tld. It then lists the fields to fill in for each provider's console. You get a sign-in flow that works locally.
