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

add-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 5d ago.

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

Implement authentication system with comprehensive user management.

Create authentication infrastructure:

  • Auth provider component with context for user state
  • Registration page with form validation and error handling
  • Login page with email/password authentication
  • Logout functionality with proper cleanup
  • Session management using JWT or session tokens
  • Protected route wrapper component
  • Middleware for authentication checking (middleware.ts)
  • User profile page with edit functionality
  • Password reset flow (request reset, verify token, set new password)
  • TypeScript types for User, Session, AuthState
  • API routes for auth operations (/api/auth/*)
  • Secure token storage (httpOnly cookies preferred)

Include proper security practices, CSRF protection, rate limiting, and accessibility. Support remember me and session persistence.

Changes

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.
