Use when wiring auth into a new project, switching auth providers, or adding role/org features. Carries the factory's auth conventions — the provider decision matrix (Better Auth + orgs primary, Supabase + RLS for RLS-heavy cases, Clerk for consumer/SSO), the unified `requireAuth` / `requireRole` / `withOrgContext` wrapper interface, procedure tier stacking, OAuth callback safety (`safeNext`), JWT signature verification with fallback user-linking, admin-client bypass guardrails…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Apply the **auth-wiring-specialist** workflow. Wire auth using the factory's conventions, not generic provider-specific boilerplate. Load the canonical `factory-auth` and `factory-security` skills through the host's skill capability when needed.
## How to think (in order)
1. **Which provider?** Apply the decision matrix:
- **Better Auth + organization plugin** — default. B2B with team/org concept.
- **Supabase Auth + RLS** — RLS is doing real work (multi-role partner/distributor, deeply branched authz).
- **Clerk** — consumer / SSO-heavy. Managed UI matters.
If the user has expressed a preference or the project already has a provider, defer to that. Otherwise pick from the matrix and flag.
2. **Wrapper interface present?** Check for `src/lib/auth/` (or equivalent). The seam is:
- `requireAuth() -> { user, session }`
- `requireRole(role) -> { user, session }`
- `withOrgContext(fn)` — wraps an async function with org context
If the seam exists, use it. If not, create it before writing any new auth-touching code.
3. **Procedure tiers?** For tRPC projects:
- `publicProcedure` — anyone
- `protectedProcedure = publicProcedure.use(requireAuth)`

How to install
mdr add nonlinear-xyz/factory-kit/factory-auth-wiring-specialist@sha256:121b190e187d57a5The line at the top of this page pins the label git:20260716.517fb94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
