cognitive-modes

cognitive-modes is a skill for Claude Code, Codex from vibeeval/vibecosystem. It costs 73 tokens per session (1,995 once invoked), scanned A, original, MIT.

A set of thinking modes matched to different coding tasks, such as deep analysis for architecture, creative thinking for product ideas, and systematic debugging for errors.

In plain words
What is it for?
Use it to guide decisions about architecture, technology choices, feature design, naming, quick fixes, and bug investigation.
Why use it?
Using the same approach for every task can lead to too much detail, too little investigation, or the wrong kind of solution. This helps choose an approach that fits the job.

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

cognitive-modes 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.

Her gorev ayni dusunme sekli gerektirmez. Mimari karar icin derin analiz, hotfix icin hizli aksiyon, bug icin sistematik izleme gerekir. Yanlis mod = yanlis sonuc.

5 Dusunme Modu

1. ANALYTICAL (Derin Analiz)

NE ZAMAN: Mimari karar, teknoloji secimi, trade-off analizi
NASIL:    Birden fazla perspektif, artilari/eksileri, uzun vadeli etki
HIZI:     Yavas ama kapsamli
TOKEN:    Yuksek (derinlemesine dusunme)

Davranis:

  • Uzun vadeli sonuclari dusun (6 ay, 1 yil)
  • "Neden" sorusunu en az 3 kez sor (5 Whys)
  • Karar oncesi risk analizi yap
  • Alternatif yaklasimlari listele

Ornek gorevler:

  • "Monolith mi microservice mi?"
  • "Hangi database kullanmaliyiz?"
  • "Auth sistemi nasil tasarlanmali?"
  • "Bu refactoring yapilmali mi?"

Prompt pattern:

Bu karari ANALYTICAL modda degerlendir:
1. En az 3 secenek belirle
2. Her secenegin 3+ artisi ve 3+ eksisini listele
3. Uzun vadeli etkileri degerlendir
4. Risk analizi yap
5. Net oneri ver (nedenle birlikte)

2. CREATIVE (Yaratici Cozum)

NE ZAMAN: Yeni feature tasarimi, UX/UI, problem cozme, naming
NASIL:    Sinir koymadan dusun, sonra daralt
HIZI:     Orta
TOKEN:    Orta

Davranis:

  • Ilk 5 fikri YARGILAMA, sadece uret
  • Farkli alanlardan analoji kullan
  • "Ya su olsa?" sorusu sor
  • Kisitlamalari gec, sonra geri getir
  • En iyi 2-3 fikri secip detaylandir

Ornek gorevler:

  • "Bu feature'i nasil tasarlayalim?"
  • "Kullanici deneyimini nasil iyilestirelim?"
  • "Bu API'nin ismi ne olmali?"
  • "Onboarding akisi nasil olmali?"

Prompt pattern:

Bu gorevi CREATIVE modda ele al:

2. Her birini tek cumlede acikla
3. En ilginc 2-3'unu sec
4. Secilenleri detaylandir
5. Final oneri ver

3. SYSTEMATIC (Adim Adim)

NE ZAMAN: Implementation, migration, setup, deployment
NASIL:    Sira onemli, her adim dogrulanmali
HIZI:     Orta-yavas
TOKEN:    Orta

Davranis:

  • Gorevi numarali adimlara bol
  • Her adimi tamamla, SONRA sonrakine gec
  • Her adim sonrasi dogrulama yap

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.
