Prompt

Write a type-safe Payload CMS `Access` control function named `adminOnly` that checks if the requesting user has the 'admin' role.

What was checked, without and with the skill

Payload Application Development

This repository (Asymmetric-al/core)

Canonical vendored source: payloadcms/skills (skills/payload/). Maintainer refresh: docs/ai/skills/payloadcms-payload/references/upstream.md.

Precedence: OpenSpec and docs/ai/rules/backend.md control durable behavior and security. Supabase schema, RLS, and Auth follow docs/ai/skills/supabase/SKILL.md and supabase/AGENTS.md. Prefer the repo's installed Payload version and vendor/payload-upstream/ when upstream examples differ from local APIs.

Workflow

Read This repository and apply the precedence rules before using generic upstream examples.
Open the local Payload entry points, starting with apps/admin/payload.config.ts and the relevant files under apps/admin/src/cms/** or apps/admin/src/cms-ui/**.
Use the matching topic reference under reference/ for the specific Payload pattern: collections, fields, hooks, access, queries, adapters, endpoints, or plugins.
Prefer repo conventions over generic examples for auth, storage, migrations, import maps, and generated types.
Run focused verification for changed Payload behavior.

Payload is a Next.js native CMS with TypeScript-first architecture, providing admin panel, database management, REST/GraphQL APIs, authentication, and file storage.
