Agent Skills: raycast-extensions

Build, maintain, and review Raycast extensions (the @raycast/api / TypeScript apps published to github.com/raycast/extensions). Use whenever the user mentions a Raycast extension, command, or tool; the @raycast/api or @raycast/utils packages; List/Detail/Form/ActionPanel/MenuBarExtra UI; useCachedPromise/useFetch/useForm hooks; getPreferenceValues; the ray CLI (ray develop/build/lint/evals); an AI extension or AI tools; preparing/publishing an extension to the Raycast Store; or reviewing an existing extension against store guidelines. Also use for "scaffold a Raycast command", "my Raycast extension errors", "fix the manifest", "add a preference", "add an OAuth login", or porting a CLI/app idea to Raycast — even if they don't say "@raycast/api" explicitly.
