Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00485 | $0.00485 |
| Opus 5.5 | $0.00194 | $0.00194 |
| Sonnet 5.5 | $0.00097 | $0.00097 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
ikinci-beyin 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
İkinci Beyin · Otomatik Bağlam Yükleme Kuralı (Cursor)
Bu klasörde her işten önce şu iki dosyayı MUTLAKA oku:
beyin/00-indeks.md: beyinde ne var, hangi dosyada ne yazıyor. Haritan bu.beyin/01-cekirdek.md: kim, ne yapıyoruz, şu an ne öncelik. Her işte lazım.
Sonra göreve göre gerekeni yükle (hepsini değil):
| İş türü | Ek olarak oku |
|---|---|
| İçerik / mail / teklif yazma | beyin/02-ses.md, beyin/05-kararlar.md |
| Bir proje üzerinde çalışma | beyin/03-projeler.md |
| Müşteri / kişiyle ilgili iş | beyin/04-kisiler.md |
| Bir aracı / kaynağı kullanma | beyin/06-kaynaklar.md |
| Karar verme / "geçen sefer ne demiştik" | beyin/05-kararlar.md |
Üretim kuralları
- Önce hangi dosyaları okuduğunu tek satırla söyle (örn. "cekirdek + projeler + kararlar okundu").
01-cekirdek.md"ne DEĞİLİZ" satırlarına ters düşme.05-kararlar.md"şu an DOKUNMA" listesine girme.- Metin üretiyorsan
02-ses.mdtonuna uy, yasak kelimeleri kullanma. - Beyinde olmayan şeyi uydurma; "beyinde bu yok, eklememi ister misin" de.
Yeni bilgi çıkarsa geri yaz
Yeni karar 05-kararlar.md en üstüne tarih atarak; yeni proje 03-projeler.md; yeni kişi 04-kisiler.md; yeni kaynak 06-kaynaklar.md; yeni dosya eklediysen 00-indeks.md haritasına satır ekle. Haftada bir HAFTALIK-DONGU.md ritüelini çalıştır.
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.

ikinci-beyin is a cursor rule published in the GitHub repository muhammedsevimli/sistemler (6 stars, last pushed 2d ago), licensed MIT.
