auth

auth is a cursor rule for Cursor from mckaywrigley/o1-pro-template-system. It costs 8 tokens per session (70 once invoked), scanned A, original, MIT.

A set of rules for adding authentication with Clerk, a service that manages user sign-in and identity. It specifies how server components and server actions should access the current user's authentication data.

In plain words
What is it for?
Use it when protecting server-rendered pages, checking the signed-in user, or writing server actions that depend on authentication.
Why use it?
It prevents authentication checks from being wired into the wrong place or used incorrectly. This helps server-side features identify users consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Auth Rules

Follow these rules when working on auth.

It uses Clerk for authentication.

General Rules

  • Import the auth helper with import { auth } from "@clerk/nextjs/server" in server components
  • await the auth helper in server action

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
