What it does
Auth is an agent skill from aiskillstore/marketplace. Authentication and access control skill for Next.js 15 + Supabase applications. Use when implementing user authentication, protecting routes, managing user sessions, enforcing role-based access control (admin/member), or working with multi-tenant family-based data isolation. Covers login/logout, registration with email verification, OAuth (GitHub), route protection for Server Components and Server Actions, admin-only features, and multi-tenant data access patterns.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/file-tree.md`, `references/flows.md` and `references/patterns.md`).
It sits in Backend & APIs, covering Authorization and RBAC, Multi-tenancy and Authentication. It works with Supabase, Next.js and GitHub. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Implementing user authentication
- Protecting routes
- Managing user sessions
- Enforcing role-based access control (admin/member)
Example prompts
- “/auth”
Requirements
- A credential in NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Import requireAuthRedirect from @/lib/auth/server-auth
- Call await requireAuthRedirect() at the start of the component
- User will be redirected to /login if not authenticated
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Auth loads about 1.6k tokens when it runs, and up to ~6.8k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 536 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 536 words (~1,647 tokens).
“This skill provides workflows for implementing authentication and access control in this Next.js 15 + Supabase application using server-side auth with httpOnly cookies, hybrid route protection, and multi-tenant family-based data isolation.”

Can I use Auth in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill auth -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/auth, .gemini/skills/auth, .github/skills/auth and .opencode/skills/auth in your project.
