Adds authentication to a Lunora app with the auth registry item (better-auth via @lunora/auth, users and sessions in D1).

  • Works in 5 steps: Add the item → Database and env vars → Wire the Worker → …
  • The user asks to add auth
  • SKILL.md covers Step 1: Add the item, Step 2: Database and env vars, Step 3: Wire the Worker and Step 4: Providers and add-ons…, plus 3 more sections
  • Calls wrangler, pnpm and openssl; needs BETTER_AUTH_SECRET and RESEND_API_KEY

What it does

Lunora Setup Auth is an agent skill from anolilab/lunora. Adds authentication to a Lunora app with the auth registry item (better-auth via @lunora/auth, users and sessions in D1). Covers email/password sign-up and sign-in, Clerk or Auth0 OAuth, magic link, email OTP, copy-in auth screens (lunora add auth-ui), wiring /api/auth/ and resolveIdentity into the Worker, and gating functions on ctx.auth.userId. Use when the user asks to "add auth", "add login/sign-in/sign-up", "protect this query", or "add Clerk/Auth0/magic link/OTP", runs lunora add auth or lunora registry add…

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Authentication. It works with Better Auth and Auth0. The repository describes itself as: Type-safe, real-time backend framework on your own Cloudflare account — Workers, Durable Objects, D1, R2, Queues. Convex-style DX, Vite-first.

When your agent uses it

  • The user asks to add auth
  • Add login/sign-in/sign-up
  • Protect this query
  • Add Clerk/Auth0/magic link/OTP

Example prompts

  • “add auth”
  • “add login/sign-in/sign-up”
  • “protect this query”
  • “/lunora-setup-auth”

Requirements

  • A credential in BETTER_AUTH_SECRET
  • A credential in RESEND_API_KEY

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Add the item
  2. Database and env vars
  3. Wire the Worker
  4. Providers and add-ons (optional)
  5. Use the session

What it can do on your machine

Read from SKILL.md and the folder at commit ad2d4c8. 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

    Shell commands in SKILL.md call:

    • wrangler
    • pnpm
    • openssl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • better-auth.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • BETTER_AUTH_SECRET
    • RESEND_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lunora Setup Auth loads about 2.8k tokens when it runs. Until then it costs about 159 tokens; SKILL.md has 891 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~159
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 891 words (~2,816 tokens).

“The auth registry item is built on @lunora/auth, a thin wrapper over better-auth. Users and sessions are stored in D1. Lunora's SessionDO is a separate TTL'd token store that @lunora/auth never calls, so don't wire it for auth. If you…”
