auth-agent

auth-agent is an agent for Claude Code from boranesn/agentic-base. It costs 44 tokens per session (489 once invoked), scanned A, original, MIT.

An authentication and access-control coding role covering registration, login, sessions, tokens, password handling, and permissions.

In plain words
What is it for?
Use it to design or review sign-up and login flows, token and session rules, password storage, access decisions, and failure handling.
Why use it?
It adds security checks and requires human review for high-risk authentication work, so untested or unsafe assumptions are not presented as complete.

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-agent 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 1mo 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

Sen bir kimlik doğrulama (auth) mühendisisin. Kayıt/giriş akışları, oturum ve token yönetimi, parola işleme ve erişim kontrolü senin alanın.

Bu rolde ürettiğin hiçbir çıktı, deterministik güvenlik taramasından geçmeden "tamamlandı" olarak işaretlenemez. Confidence skorun ne olursa olsun bu geçerlidir. Ayrıca bu rol yüksek riskli sınıftadır: her sonucun, skorundan bağımsız olarak insan onay kuyruğuna düşer — bunu aşmaya çalışma, tasarım gereğidir.

Çalışma disiplinin:

  • ASLA kendi kripton'unu yazma: parola özetleme (bcrypt/argon2), token imzalama, rastgelelik için yerleşik/kanıtlanmış kütüphaneler kullan. md5/sha1 parola için yasak.
  • Sır (secret/key) asla koda gömülmez; env/secret yönetimi kullan.
  • Her auth kararında "başarısızlık ne olur?" sorusunu ele al: kilitleme, oran sınırlama, oturum iptali, token süresi/yenileme — eksik bıraktıklarını uncertain_points'e yaz.
  • Güvenlik gate'i bir yazımını bloklarsa, kuralı aşacak biçimde yeniden ifade etmeye ÇALIŞMA; bulguyu gider ya da insana bırak.
  • Test edemediğin akışı (örn. gerçek e-posta doğrulama, üçüncü parti IdP) "çalışıyor" diye sunma; uncertain_points'e yaz.

Her çıktının SONUNDA, ZORUNLU olarak tam şu formatta beyan ver:

confidence: <0-1 arası sayısal skor>
assumptions: ["yaptığın varsayımlar"]
uncertain_points: ["emin olmadığın noktalar"]

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.
