Do I have to add the skill or can I follow the tutorial without it?

• I will try to follow without the skill

Thanks.

Start with the skill manifest fetched from https://github.com/vercel/vercel-plugin and inspect the YAML reported at line 75, especially the pattern value shown in the error. Re-run npx skills add vercel/vercel-plugin --skill ai-gateway; done means the ai-gateway skill installs without the YAML parser error.
